Add placeholder text inside UITextView in Swift

Question

How can I add a placeholder in a UITextView  similar to the one you can set for UITextField  in Swift

Here is my way of solving this problem  Swift 4    The idea was to make the simplest possible solution which allows to use placeholders of different colors  resizes to placeholders size  will not overwrite a delegate meanwhile keeping all UITextView functions work as expected   import UIKit  class PlaceholderTextView  UITextView       var placeholderColor  UIColor    lightGray     var defaultTextColor  UIColor    black      private var isShowingPlaceholder   false           didSet               if isShowingPlaceholder                   text   placeholder                 textColor   placeholderColor               else                   textColor   defaultTextColor                                    var placeholder  String            didSet               isShowingPlaceholder    hasText                       objc private func textViewDidBeginEditing notification  Notification            textColor   defaultTextColor         if isShowingPlaceholder   text   nil               objc private func textViewDidEndEditing notification  Notification            isShowingPlaceholder    hasText               MARK  - Construction -     override init frame  CGRect  textContainer  NSTextContainer             super init frame  frame  textContainer  textContainer          setup              required init  coder aDecoder  NSCoder            super init coder  aDecoder          setup              private func setup             NotificationCenter default addObserver self  selector   selector textViewDidBeginEditing notification     name  UITextView textDidBeginEditingNotification  object  nil          NotificationCenter default addObserver self  selector   selector textViewDidEndEditing notification     name  UITextView textDidEndEditingNotification  object  nil                MARK  - Destruction -     deinit   NotificationCenter default removeObserver self

TEXT VIEW DELEGATE METHODS Use these two delegate methods and also write UITextViewDelegate in your class func textViewDidBeginEditing   textView  UITextView        if  commentsTextView text     quot Type Your Comments quot                 commentsTextView text   nil         commentsTextView textColor   UIColor darkGray          func textViewDidEndEditing   textView  UITextView        if commentsTextView text isEmpty               commentsTextView text    quot Type Your Comments quot          commentsTextView textColor   UIColor darkGray           textView resignFirstResponder

Swift   Add your text view programmatically or via Interface Builder  if the last  create the outlet    IBOutlet weak var yourTextView  UITextView    Please add the delegate  UITextViewDelegate    class ViewController  UIViewController  UITextViewDelegate     In the viewDidLoad method  do add the following   override func viewDidLoad             super viewDidLoad              Do any additional setup after loading the view  typically from a nib       yourTextView delegate   self     yourTextView text    Placeholder text goes right here         yourTextView textColor   UIColor lightGray   Now let me introduce the magic part  add this function   func textViewDidBeginEditing   textView  UITextView         if yourTextView textColor    UIColor lightGray           yourTextView text              yourTextView textColor   UIColor black           Do note that this will execute whenever editing starts  there we will check conditions to tell the state  using the color property  Setting text to nil i do not recommend  Right after that  we set the text color to desired  in this case  black   Now add this function too   func textViewDidEndEditing   textView  UITextView         if yourTextView text                  yourTextView text    Placeholder text              yourTextView textColor   UIColor lightGray           Let me insist  do not compare to nil  i have already tried that and it would not work  We then set the values back to placeholder style  and set the color back to placeholder color because it is a condition to check in textViewDidBeginEditing

Another solution could be to use keyboardWillHide and keyboardWillShow notifications  as I did    First you need to handle listening  and unlistening to the notifications in the  viewWillAppear and viewWillAppear methods respectively  to handle memory leaks    override func viewWillAppear   animated  Bool        super viewWillAppear animated      setupKeyboardNotificationListeners enable  true     override func viewWillDisappear   animated  Bool        super viewWillDisappear animated      setupKeyboardNotificationListeners enable  false      Then the method to handle listening unlistening to the notifications    private func setupKeyboardNotificationListeners enable  Bool            if enable               NotificationCenter default addObserver self  selector   selector self keyboardWillShow   name  NSNotification Name UIKeyboardWillShow  object  nil              NotificationCenter default addObserver self  selector   selector self keyboardWillHide   name  NSNotification Name UIKeyboardWillHide  object  nil            else               NotificationCenter default removeObserver self                    Then in the both methods for keyboardWillHide and keyboardWillShow you handle the placeholder and color changes of the text     objc func keyboardWillShow notification  NSNotification        if self textView text    self placeholder           self textView text              self textView textColor    black           objc func keyboardWillHide notification  NSNotification        if self textView text isEmpty           self textView text   self placeholder         self textView textColor    lightGrey           I found this solution to be the best one so far since the text will be removed as soon as the keyboard appears instead of when the user starts typing  which can cause confusion

I know this is a an old question but wanted to share what I thought was a useful way of extending UITextView to have placeholderText and placeholderColor fields   Basically you cast the UITextView into a UITextField and then set the attributedPlaceholder field  PlaceholderText and placeholderColor are IBInspectable fields  so their values can be set in IB and behaves exactly as the UITextField placeholder functionality   UITextView Extend h   import  lt UIKit UIKit h gt    interface UITextView  Extend    property  nonatomic  IBInspectable NSString  placeholderText   property  nonatomic  IBInspectable UIColor  placeholderColor    end   UITextView Extend m   import  UITextView Extend h   import  objc runtime h    implementation UITextView  Extend   -  void setPlaceholderText  NSString   placeholderText       objc setAssociatedObject self   selector placeholderText   placeholderText  OBJC ASSOCIATION RETAIN NONATOMIC        self updatePlaceholderText      -  NSString  placeholderText       return objc getAssociatedObject self   selector placeholderText       -  void setPlaceholderColor  UIColor   placeholderColor       objc setAssociatedObject self   selector placeholderColor   placeholderColor  OBJC ASSOCIATION RETAIN NONATOMIC        self updatePlaceholderText      -  UIColor  placeholderColor       return objc getAssociatedObject self   selector placeholderColor       -  void updatePlaceholderText       NSString  text   self placeholderText      UIColor  color   self placeholderColor      if text  amp  amp  color                UITextField  textField    UITextField  self          textField attributedPlaceholder     NSAttributedString alloc  initWithString text attributes   NSForegroundColorAttributeName color              end

Based on some of the great suggestions here already  I was able to put together the following lightweight  Interface-Builder-compatible subclass of UITextView  which   Includes configurable placeholder text  styled just like that of UITextField  Doesn t require any additional subviews or constraints  Doesn t require any delegation or other behaviour from the ViewController  Doesn t require any notifications  Keeps that placeholder text fully separated from any outside classes looking at the field s text property   Any improvement suggestions are welcome  especially if there s any way to pull iOS s placeholder color programatically  rather than hard-coding it  Swift v5  import UIKit  IBDesignable class TextViewWithPlaceholder  UITextView            override var text  String       Ensures that the placeholder text is never returned as the field s text         get               if showingPlaceholder                   return  quot  quot     When showing the placeholder  there s no real text to return               else   return super text                     set   super text   newValue              IBInspectable var placeholderText  String    quot  quot       IBInspectable var placeholderTextColor  UIColor   UIColor red  0 78  green  0 78  blue  0 80  alpha  1 0     Standard iOS placeholder color   C7C7CD   See https   stackoverflow com questions 31057746 whats-the-default-color-for-placeholder-text-in-uitextfield     private var showingPlaceholder  Bool   true    Keeps track of whether the field is currently showing a placeholder          override func didMoveToWindow             super didMoveToWindow           if text isEmpty               showPlaceholderText      Load up the placeholder text when first appearing  but not if coming back to a view where text was already entered                          override func becomeFirstResponder   - gt  Bool              If the current text is the placeholder  remove it         if showingPlaceholder               text   nil             textColor   nil    Put the text back to the default  unmodified color             showingPlaceholder   false                   return super becomeFirstResponder                  override func resignFirstResponder   - gt  Bool              If there s no text  put the placeholder back         if text isEmpty               showPlaceholderText                     return super resignFirstResponder                  private func showPlaceholderText             showingPlaceholder   true         textColor   placeholderTextColor         text   placeholderText

Swift 5 2  Standalone class  Use this if you want a class which you can use anywhere as it is self contained  import UIKit class PlaceHolderTextView UITextView  UITextViewDelegate  var placeholderText    placeholderText   override func willMove toSuperview newSuperview  UIView         textColor    lightText     delegate   self    func textViewDidBeginEditing   textView  UITextView        if textView text    placeholderText          placeholderText   textView text         textView text              textView textColor    darkText          func textViewDidEndEditing   textView  UITextView        if textView text                textView text   placeholderText         textColor    lightText                 The key here is the willMove toSuperView   function as it allows you to setup the view before being added to another view s hierarchy  similar to viewDidLoad viewWillAppear in ViewControllers

I did this by using two different text views    One in the background that is used as a placeholder  One in the foreground  with a transparent background  that the user actually types in    The idea is that once the user starts typing stuff in the foreground view  the placeholder in the background disappears  and reappears if the user deletes everything   So it behaves exactly like a placeholder for the single line text field   Here s the code I used for it  Note that descriptionField is the field the user types in and descriptionPlaceholder is the one in the background   func textViewDidChange descriptionField  UITextView        if descriptionField text isEmpty    false           descriptionPlaceholder text            else           descriptionPlaceholder text   descriptionPlaceholderText

no there is not any placeholder available for textview  you have to put label above it when user enter in textview then hide it or set by default value when user enters remove all values

Swift 3 1  This extension worked well for me  https   github com devxoul UITextView-Placeholder  Here is a code snippet   Install it via pod   pod  UITextView Placeholder      gt  1 2    Import it to your class  import UITextView Placeholder   And add placeholder property to your already created UITextView  textView placeholder    Put some detail    Thats it    Here how it looks  Third box is a UITextView

There is no such property in ios to add placeholder directly in TextView rather you can add a label and show hide on the change in textView  SWIFT 2 0 and make sure to implement the textviewdelegate  func textViewDidChange TextView  UITextView      if  txtShortDescription text                     self lblShortDescription hidden   false           else               self lblShortDescription hidden   true

I am surprised that no one mentioned NSTextStorageDelegate  UITextViewDelegate s methods will only be triggered by user interaction  but not programmatically  E g  when you set a text view s text property programmatically  you ll have to set the placeholder s visibility yourself  because the delegate methods will not be called   However  with NSTextStorageDelegate s textStorage   didProcessEditing range changeInLength   method  you ll be notified of any change to the text  even if it s done programmatically  Just assign it like this   textView textStorage delegate   self    In UITextView  this delegate property is nil by default  so it won t affect any default behaviour    Combine it with the UILabel technique  clearlight demonstrates  one can easily wrap the whole UITextView s placeholder implementation into an extension   extension UITextView        private class PlaceholderLabel  UILabel          private var placeholderLabel  PlaceholderLabel           if let label   subviews compactMap     0 as  PlaceholderLabel    first               return label           else               let label   PlaceholderLabel frame   zero              label font   font             addSubview label              return label                       IBInspectable     var placeholder  String           get               return subviews compactMap     0 as  PlaceholderLabel    first  text                         set               let placeholderLabel   self placeholderLabel             placeholderLabel text   newValue             placeholderLabel numberOfLines   0             let width   frame width - textContainer lineFragmentPadding   2             let size   placeholderLabel sizeThatFits CGSize width  width  height   greatestFiniteMagnitude               placeholderLabel frame size height   size height             placeholderLabel frame size width   width             placeholderLabel frame origin   CGPoint x  textContainer lineFragmentPadding  y  textContainerInset top               textStorage delegate   self                     extension UITextView  NSTextStorageDelegate        public func textStorage   textStorage  NSTextStorage  didProcessEditing editedMask  NSTextStorageEditActions  range editedRange  NSRange  changeInLength delta  Int            if editedMask contains  editedCharacters                placeholderLabel isHidden    text isEmpty                      Note that the use of a private  nested  class called PlaceholderLabel  It has no implementation at all  but it provides us a way to identify the placeholder label  which is far more  swifty  than using the tag property    With this approach  you can still assign the delegate of the UITextView to someone else   You don t even have to change your text views  classes  Just add the extension s  and you will be able to assign a placeholder string to every UITextView in your project  even in the Interface Builder   I left out the implementation of a placeholderColor property for clarity reasons  but it can be implemented for just a few more lines with a similar computed variable to placeholder

Our solution avoids mucking with the UITextView text and textColor properties  which is handy if you re maintaining a character counter   It s simple   1  Create a dummy UITextView in Storyboard with the same properties as the master UITextView  Assign placeholder text to the dummy text   2  Align the top  left  and right edges of the two UITextViews   3  Place the dummy behind the master   4  Override the textViewDidChange textView   delegate function of the master  and show the dummy if the master has 0 characters  Otherwise  show the master   This assumes both UITextViews have transparent backgrounds  If they do not  place the dummy on top when there are 0 characters  and push it underneath when there are   0 characters  You will also have to swap responders to make sure the cursor follows the right UITextView

Updated for Swift 4  UITextView doesn t inherently have a placeholder property so you d have to create and manipulate one programmatically using UITextViewDelegate methods  I recommend using either solution  1 or  2 below depending on the desired behavior   Note  For either solution  add UITextViewDelegate to the class and set textView delegate   self to use the text view   s delegate methods     Solution  1 - If you want the placeholder to disappear as soon as the user selects the text view   First set the UITextView to contain the placeholder text and set it to a light gray color to mimic the look of a UITextField s placeholder text  Either do so in the viewDidLoad or upon the text view s creation   textView text    Placeholder  textView textColor   UIColor lightGray   Then when the user begins to edit the text view  if the text view contains a placeholder  i e  if its text color is light gray  clear the placeholder text and set the text color to black in order to accommodate the user s entry   func textViewDidBeginEditing   textView  UITextView        if textView textColor    UIColor lightGray           textView text   nil         textView textColor   UIColor black           Then when the user finishes editing the text view and it s resigned as the first responder  if the text view is empty  reset its placeholder by re-adding the placeholder text and setting its color to light gray   func textViewDidEndEditing   textView  UITextView        if textView text isEmpty           textView text    Placeholder          textView textColor   UIColor lightGray             Solution  2 - If you want the placeholder to show whenever the text view is empty  even if the text view   s selected   First set the placeholder in the viewDidLoad   textView text    Placeholder  textView textColor   UIColor lightGray  textView becomeFirstResponder    textView selectedTextRange   textView textRange from  textView beginningOfDocument  to  textView beginningOfDocument     Note  Since the OP wanted to have the text view selected as soon as the view loads  I incorporated text view selection into the above code  If this is not your desired behavior and you do not want the text view selected upon view load  remove the last two lines from the above code chunk    Then utilize the shouldChangeTextInRange UITextViewDelegate method  like so   func textView   textView  UITextView  shouldChangeTextIn range  NSRange  replacementText text  String  - gt  Bool           Combine the textView text and the replacement text to        create the updated text string     let currentText String   textView text     let updatedText    currentText as NSString  replacingCharacters in  range  with  text          If updated text view will be empty  add the placeholder        and set the cursor to the beginning of the text view     if updatedText isEmpty            textView text    Placeholder          textView textColor   UIColor lightGray          textView selectedTextRange   textView textRange from  textView beginningOfDocument  to  textView beginningOfDocument                Else if the text view s placeholder is showing and the        length of the replacement string is greater than 0  set         the text color to black then set its text to the        replacement string      else if textView textColor    UIColor lightGray  amp  amp   text isEmpty           textView textColor   UIColor black         textView text   text               For every other case  the text should change with the usual        behavior        else           return true                  otherwise return false since the updates have already        been made     return false     And also implement textViewDidChangeSelection to prevent the user from changing the position of the cursor while the placeholder s visible   Note  textViewDidChangeSelection is called before the view loads so only check the text view s color if the window is visible    func textViewDidChangeSelection   textView  UITextView        if self view window    nil           if textView textColor    UIColor lightGray               textView selectedTextRange   textView textRange from  textView beginningOfDocument  to  textView beginningOfDocument

A simple and quick solution that works for me is     IBDesignable class PlaceHolderTextView  UITextView         IBInspectable var placeholder  String                 didSet               updatePlaceHolder                         IBInspectable var placeholderColor  UIColor   UIColor gray           didSet               updatePlaceHolder                        private var originalTextColor   UIColor darkText     private var originalText  String           private func updatePlaceHolder              if self text          self text    placeholder                 self text   placeholder             self textColor   placeholderColor             if let color   self textColor                    self originalTextColor   color                           self originalText                else               self textColor   self originalTextColor             self originalText   self text                       override func becomeFirstResponder   - gt  Bool           let result   super becomeFirstResponder           self text   self originalText         self textColor   self originalTextColor         return result           override func resignFirstResponder   - gt  Bool           let result   super resignFirstResponder           updatePlaceHolder            return result

This is what I did  Leaning towards code clarity and simplicity  I needed to add a textView that will get some additional notes on my app  This additional notes can be created or amended after being saved  See below  HTH     class NotesTextView  UITextView        var placeholder    quot  quot            didSet               showPlaceholder                               if the text is the placeholder  then assign a color fitting for a        placeholder text  else  assign it your color of choice      override var text  String            didSet               textColor   text    placeholder    tertiaryLabel    systemBlue                               override init frame  CGRect  textContainer  NSTextContainer             super init frame  frame  textContainer  textContainer                   delegate   self           config your font and translateAutoResizingMaskIntoConstraints here                required init  coder  NSCoder            fatalError  quot init coder   has not been implemented quot                  private func showPlaceholder             text   placeholder                private func hidePlaceholder             text    quot  quot           extension NotesTextView  UITextViewDelegate       func textViewDidBeginEditing   textView  UITextView            if text    placeholder               hidePlaceholder                            func textViewDidEndEditing   textView  UITextView            if text isEmpty               showPlaceholder

Contrary to just about every answer on this post  UITextView does have a placeholder property  For reasons beyond my comprehension  it is only exposed in IB  as such    lt userDefinedRuntimeAttributes gt     lt userDefinedRuntimeAttribute type  string  keyPath  placeholder  value  My Placeholder   gt   lt  userDefinedRuntimeAttributes gt    So if you are using storyboards and a static placeholder will suffice  just set the property on the inspector    You can also set this property in code like this   textView setValue  My Placeholder   forKeyPath   placeholder     Its cloudy as to weather this is accessed via private API  as the property is exposed   I haven t tried submitting with this method  But I will be submitting this way shortly and will update this answer accordingly   UPDATE   I have shipped this code in multiple releases with no issues from Apple   UPDATE  This will only work in Xcode pre 11 2
