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

User · Answer

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

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

No need to add any third party library  Just use below code    class SubmitReviewVC   UIViewController  UITextViewDelegate     IBOutlet var txtMessage   UITextView  var lblPlaceHolder   UILabel   override func viewDidLoad         super viewDidLoad        txtMessage delegate   self     lblPlaceHolder   UILabel       lblPlaceHolder text    quot Enter message    quot      lblPlaceHolder font   UIFont systemFont ofSize  txtMessage font  pointSize      lblPlaceHolder sizeToFit       txtMessage addSubview lblPlaceHolder      lblPlaceHolder frame origin   CGPoint x  5  y   txtMessage font  pointSize     2      lblPlaceHolder textColor   UIColor lightGray     lblPlaceHolder isHidden    txtMessage text isEmpty    func textViewDidChange   textView  UITextView        lblPlaceHolder isHidden    textView text isEmpty

I believe this is a very clean solution  It adds a dummy text view underneath the actual text view and shows or hides it depending on the text in the actual text view   import Foundation import UIKit  class TextViewWithPlaceholder  UITextView        private var placeholderTextView  UITextView   UITextView        var placeholder  String            didSet               placeholderTextView text   placeholder                      override var text  String            didSet               placeholderTextView isHidden   text isEmpty    false                      override init frame  CGRect  textContainer  NSTextContainer             super init frame  frame  textContainer  textContainer          commonInit              required init  coder aDecoder  NSCoder            super init coder  aDecoder          commonInit              private func commonInit             applyCommonTextViewAttributes to  self          configureMainTextView           addPlaceholderTextView           NotificationCenter default addObserver self                                                 selector   selector textDidChange                                                  name  UITextView textDidChangeNotification                                                 object  nil             func addPlaceholderTextView             applyCommonTextViewAttributes to  placeholderTextView          configurePlaceholderTextView           insertSubview placeholderTextView  at  0             private func applyCommonTextViewAttributes to textView  UITextView            textView translatesAutoresizingMaskIntoConstraints   false         textView textContainer lineFragmentPadding   0         textView textContainerInset   UIEdgeInsets top  10                                                     left  10                                                     bottom  10                                                     right  10             private func configureMainTextView                Do any configuration of the actual text view here            private func configurePlaceholderTextView             placeholderTextView text   placeholder         placeholderTextView font   font         placeholderTextView textColor   UIColor lightGray         placeholderTextView frame   bounds         placeholderTextView autoresizingMask     flexibleWidth   flexibleHeight             override func layoutSubviews             super layoutSubviews           placeholderTextView frame   bounds             objc func textDidChange             placeholderTextView isHidden    text isEmpty

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

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

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

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

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

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

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

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

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

I don t know why people over complicate this issue so much     It s fairly straight forward and simple  Here s a subclass of UITextView that provides the requested functionality    -  void customInit       self contentMode   UIViewContentModeRedraw        NSNotificationCenter defaultCenter  addObserver self selector  selector textChanged   name UITextViewTextDidChangeNotification object nil          -  void textChanged  NSNotification   notification               if  notification object    self                if self textStorage length    0     self textStorage length                     self setNeedsDisplay                                        pragma mark - Setters      -  void setPlaceholderText  NSString   placeholderText withFont  UIFont   font               self placeholderText   placeholderText          self placeholderTextFont   font                -  void drawRect  CGRect rect                super drawRect rect             UIColor lightGrayColor  setFill            if  self textStorage length    0                return                     CGRect inset   CGRectInset rect  8  8    Default rect insets for textView         NSDictionary  attributes      NSFontAttributeName  self placeholderTextFont  NSForegroundColorAttributeName   UIColor grayColor             self placeholderText drawInRect inset withAttributes attributes
