I'd like to change the color of the placeholder text I set in my UITextField
controls, to make it black.
I'd prefer to do this without using normal text as the placeholder and having to override all the methods to imitate the behaviour of a placeholder.
I believe if I override this method:
- (void)drawPlaceholderInRect:(CGRect)rect
then I should be able to do this. But I'm unsure how to access the actual placeholder object from within this method.
This question is related to
ios
uitextfield
I would suggest another solution. Since the placeholder text uses the default font settings of the textfield, just set the initial font color to the placeholder font color you want. Then set the delegate of your UITextField and implement the following methods:
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
//set color for text input
textField.textColor = [UIColor blackColor];
return YES;
}
- (BOOL)textFieldShouldClear:(UITextField *)textField
{
//set color for placeholder text
textField.textColor = [UIColor redColor];
return YES;
}
So, if a user starts typing in the textfield the color of the text changes to black and after the textfield gets cleared again the placeholder text will appear in red color again.

For those using Monotouch (Xamarin.iOS), here's Adam's answer, translated to C#:
public class MyTextBox : UITextField
{
public override void DrawPlaceholder(RectangleF rect)
{
UIColor.FromWhiteAlpha(0.5f, 1f).SetFill();
new NSString(this.Placeholder).DrawString(rect, Font);
}
}
Categories FTW. Could be optimized to check for effective color change.
#import <UIKit/UIKit.h>
@interface UITextField (OPConvenience)
@property (strong, nonatomic) UIColor* placeholderColor;
@end
#import "UITextField+OPConvenience.h"
@implementation UITextField (OPConvenience)
- (void) setPlaceholderColor: (UIColor*) color {
if (color) {
NSMutableAttributedString* attrString = [self.attributedPlaceholder mutableCopy];
[attrString setAttributes: @{NSForegroundColorAttributeName: color} range: NSMakeRange(0, attrString.length)];
self.attributedPlaceholder = attrString;
}
}
- (UIColor*) placeholderColor {
return [self.attributedPlaceholder attribute: NSForegroundColorAttributeName atIndex: 0 effectiveRange: NULL];
}
@end
iOS 6 and later offers attributedPlaceholder
on UITextField
.
iOS 3.2 and later offers setAttributes:range:
on NSMutableAttributedString
.
You can do the following:
NSMutableAttributedString *ms = [[NSMutableAttributedString alloc] initWithString:self.yourInput.placeholder];
UIFont *placeholderFont = self.yourInput.font;
NSRange fullRange = NSMakeRange(0, ms.length);
NSDictionary *newProps = @{NSForegroundColorAttributeName:[UIColor yourColor], NSFontAttributeName:placeholderFont};
[ms setAttributes:newProps range:fullRange];
self.yourInput.attributedPlaceholder = ms;
Iam new to xcode and i found a way around to the same effect.
I placed a uilabel in place of place holder with the desired format and hide it in
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
switch (textField.tag)
{
case 0:
lblUserName.hidden=YES;
break;
case 1:
lblPassword.hidden=YES;
break;
default:
break;
}
}
I agree its a work around and not a real solution but the effect was same got it from this link
NOTE: Still works on iOS 7 :|
For set Attributed Textfield Placeholder with Multiple color ,
Just specify the Text ,
//txtServiceText is your Textfield
_txtServiceText.placeholder=@"Badal/ Shah";
NSMutableAttributedString *mutable = [[NSMutableAttributedString alloc] initWithString:_txtServiceText.placeholder];
[mutable addAttribute: NSForegroundColorAttributeName value:[UIColor whiteColor] range:[_txtServiceText.placeholder rangeOfString:@"Badal/"]]; //Replace it with your first color Text
[mutable addAttribute: NSForegroundColorAttributeName value:[UIColor orangeColor] range:[_txtServiceText.placeholder rangeOfString:@"Shah"]]; // Replace it with your secondcolor string.
_txtServiceText.attributedPlaceholder=mutable;
Output :-
To handle both vertical and horizontal alignment as well as color of placeholder in iOS7. drawInRect and drawAtPoint no longer use current context fillColor.
Obj-C
@interface CustomPlaceHolderTextColorTextField : UITextField
@end
@implementation CustomPlaceHolderTextColorTextField : UITextField
-(void) drawPlaceholderInRect:(CGRect)rect {
if (self.placeholder) {
// color of placeholder text
UIColor *placeHolderTextColor = [UIColor redColor];
CGSize drawSize = [self.placeholder sizeWithAttributes:[NSDictionary dictionaryWithObject:self.font forKey:NSFontAttributeName]];
CGRect drawRect = rect;
// verticially align text
drawRect.origin.y = (rect.size.height - drawSize.height) * 0.5;
// set alignment
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
paragraphStyle.alignment = self.textAlignment;
// dictionary of attributes, font, paragraphstyle, and color
NSDictionary *drawAttributes = @{NSFontAttributeName: self.font,
NSParagraphStyleAttributeName : paragraphStyle,
NSForegroundColorAttributeName : placeHolderTextColor};
// draw
[self.placeholder drawInRect:drawRect withAttributes:drawAttributes];
}
}
@end
I had already faced this issue. In my case below code is correct.
Objective C
[textField setValue:[UIColor whiteColor] forKeyPath:@"_placeholderLabel.textColor"];
For Swift 4.X
tf_mobile.setValue(UIColor.white, forKeyPath: "_placeholderLabel.textColor")
For iOS 13 Swift Code
tf_mobile.attributedPlaceholder = NSAttributedString(string:"PlaceHolder Text", attributes: [NSAttributedString.Key.foregroundColor: UIColor.red])
You can also use below code for iOS 13
let iVar = class_getInstanceVariable(UITextField.self, "_placeholderLabel")!
let placeholderLabel = object_getIvar(tf_mobile, iVar) as! UILabel
placeholderLabel.textColor = .red
Hope, this may help you.
Overriding drawPlaceholderInRect:
would be the correct way, but it does not work due to a bug in the API (or the documentation).
The method never gets called on an UITextField
.
See also drawTextInRect on UITextField not called
You might use digdog's solution. As I am not sure if that gets past Apples review, I chose a different solution: Overlay the text field with my own label which imitates the placeholder behaviour.
This is a bit messy though. The code looks like this (Note I am doing this inside a subclass of TextField):
@implementation PlaceholderChangingTextField
- (void) changePlaceholderColor:(UIColor*)color
{
// Need to place the overlay placeholder exactly above the original placeholder
UILabel *overlayPlaceholderLabel = [[[UILabel alloc] initWithFrame:CGRectMake(self.frame.origin.x + 8, self.frame.origin.y + 4, self.frame.size.width - 16, self.frame.size.height - 8)] autorelease];
overlayPlaceholderLabel.backgroundColor = [UIColor whiteColor];
overlayPlaceholderLabel.opaque = YES;
overlayPlaceholderLabel.text = self.placeholder;
overlayPlaceholderLabel.textColor = color;
overlayPlaceholderLabel.font = self.font;
// Need to add it to the superview, as otherwise we cannot overlay the buildin text label.
[self.superview addSubview:overlayPlaceholderLabel];
self.placeholder = nil;
}
Swift 5 WITH CAVEAT.
let attributes = [ NSAttributedString.Key.foregroundColor: UIColor.someColor ]
let placeHolderString = NSAttributedString(string: "DON'T_DELETE", attributes: attributes)
txtField.attributedPlaceholder = placeHolderString
The caveat being that you MUST enter a non-empty String
where "DON'T_DELETE" is, even if that string is set in code elsewhere. Might save you five minutes of head-sctratching.
in swift 3.X
textField.attributedPlaceholder = NSAttributedString(string: "placeholder text", attributes:[NSForegroundColorAttributeName: UIColor.black])
in swift 5
textField.attributedPlaceholder = NSAttributedString(string: "placeholder text", attributes: [NSAttributedString.Key.foregroundColor : UIColor.black])
For Xamarin.iOS developers, I found it from this document https://developer.xamarin.com/api/type/Foundation.NSAttributedString/
textField.AttributedPlaceholder = new NSAttributedString ("Hello, world",new UIStringAttributes () { ForegroundColor = UIColor.Red });
I needed to keep the placeholder alignment so adam's answer was not enough for me.
To solve this I used a small variation that I hope will help some of you too:
- (void) drawPlaceholderInRect:(CGRect)rect {
//search field placeholder color
UIColor* color = [UIColor whiteColor];
[color setFill];
[self.placeholder drawInRect:rect withFont:self.font lineBreakMode:UILineBreakModeTailTruncation alignment:self.textAlignment];
}
[txt_field setValue:ColorFromHEX(@"#525252") forKeyPath:@"_placeholderLabel.textColor"];
Why don't you just use UIAppearance
method:
[[UILabel appearanceWhenContainedIn:[UITextField class], nil] setTextColor:[UIColor whateverColorYouNeed]];
Maybe you want to try this way, but Apple might warn you about accessing private ivar:
[self.myTextField setValue:[UIColor darkGrayColor]
forKeyPath:@"_placeholderLabel.textColor"];
NOTE
This is not working on iOS 7 anymore, according to Martin Alléus.
Swift version. Probably it would help someone.
class TextField: UITextField {
override var placeholder: String? {
didSet {
let placeholderString = NSAttributedString(string: placeholder!, attributes: [NSForegroundColorAttributeName: UIColor.whiteColor()])
self.attributedPlaceholder = placeholderString
}
}
}
In order to change placeholder color in storyboard, create an extension with next code. (feel free to update this code, if you think, it can be clearer and safer).
extension UITextField {
@IBInspectable var placeholderColor: UIColor {
get {
guard let currentAttributedPlaceholderColor = attributedPlaceholder?.attribute(NSForegroundColorAttributeName, at: 0, effectiveRange: nil) as? UIColor else { return UIColor.clear }
return currentAttributedPlaceholderColor
}
set {
guard let currentAttributedString = attributedPlaceholder else { return }
let attributes = [NSForegroundColorAttributeName : newValue]
attributedPlaceholder = NSAttributedString(string: currentAttributedString.string, attributes: attributes)
}
}
}
extension UITextField {
@IBInspectable var placeholderColor: UIColor {
get {
return attributedPlaceholder?.attribute(.foregroundColor, at: 0, effectiveRange: nil) as? UIColor ?? .clear
}
set {
guard let attributedPlaceholder = attributedPlaceholder else { return }
let attributes: [NSAttributedStringKey: UIColor] = [.foregroundColor: newValue]
self.attributedPlaceholder = NSAttributedString(string: attributedPlaceholder.string, attributes: attributes)
}
}
}
extension UITextField {
@IBInspectable var placeholderColor: UIColor {
get {
return attributedPlaceholder?.attribute(.foregroundColor, at: 0, effectiveRange: nil) as? UIColor ?? .clear
}
set {
guard let attributedPlaceholder = attributedPlaceholder else { return }
let attributes: [NSAttributedString.Key: UIColor] = [.foregroundColor: newValue]
self.attributedPlaceholder = NSAttributedString(string: attributedPlaceholder.string, attributes: attributes)
}
}
}
The best i can do for both iOS7 and less is:
- (CGRect)placeholderRectForBounds:(CGRect)bounds {
return [self textRectForBounds:bounds];
}
- (CGRect)editingRectForBounds:(CGRect)bounds {
return [self textRectForBounds:bounds];
}
- (CGRect)textRectForBounds:(CGRect)bounds {
CGRect rect = CGRectInset(bounds, 0, 6); //TODO: can be improved by comparing font size versus bounds.size.height
return rect;
}
- (void)drawPlaceholderInRect:(CGRect)rect {
UIColor *color =RGBColor(65, 65, 65);
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")) {
[self.placeholder drawInRect:rect withAttributes:@{NSFontAttributeName:self.font, UITextAttributeTextColor:color}];
} else {
[color setFill];
[self.placeholder drawInRect:rect withFont:self.font];
}
}
You can Change the Placeholder textcolor to any color which you want by using the below code.
UIColor *color = [UIColor lightTextColor];
YOURTEXTFIELD.attributedPlaceholder = [[NSAttributedString alloc] initWithString:@"PlaceHolder Text" attributes:@{NSForegroundColorAttributeName: color}];
This works in Swift <3.0:
myTextField.attributedPlaceholder =
NSAttributedString(string: "placeholder text", attributes: [NSForegroundColorAttributeName : UIColor.redColor()])
Tested in iOS 8.2 and iOS 8.3 beta 4.
Swift 3:
myTextfield.attributedPlaceholder =
NSAttributedString(string: "placeholder text", attributes: [NSForegroundColorAttributeName : UIColor.red])
Swift 4:
myTextfield.attributedPlaceholder =
NSAttributedString(string: "placeholder text", attributes: [NSAttributedStringKey.foregroundColor: UIColor.red])
Swift 4.2:
myTextfield.attributedPlaceholder =
NSAttributedString(string: "placeholder text", attributes: [NSAttributedString.Key.foregroundColor: UIColor.red])
This solution for Swift 4.1
textName.attributedPlaceholder = NSAttributedString(string: textName.placeholder!, attributes: [NSAttributedStringKey.foregroundColor : UIColor.red])
The following only with iOS6+ (as indicated in Alexander W's comment):
UIColor *color = [UIColor grayColor];
nameText.attributedPlaceholder =
[[NSAttributedString alloc]
initWithString:@"Full Name"
attributes:@{NSForegroundColorAttributeName:color}];
In Swift:
if let placeholder = yourTextField.placeholder {
yourTextField.attributedPlaceholder = NSAttributedString(string:placeholder,
attributes: [NSForegroundColorAttributeName: UIColor.blackColor()])
}
In Swift 4.0:
if let placeholder = yourTextField.placeholder {
yourTextField.attributedPlaceholder = NSAttributedString(string:placeholder,
attributes: [NSAttributedStringKey.foregroundColor: UIColor.black])
}
Since the introduction of attributed strings in UIViews in iOS 6, it's possible to assign a color to the placeholder text like this:
if ([textField respondsToSelector:@selector(setAttributedPlaceholder:)]) {
UIColor *color = [UIColor blackColor];
textField.attributedPlaceholder = [[NSAttributedString alloc] initWithString:placeholderText attributes:@{NSForegroundColorAttributeName: color}];
} else {
NSLog(@"Cannot set placeholder text's color, because deployment target is earlier than iOS 6.0");
// TODO: Add fall-back code to set placeholder color.
}
With this we can change the color of textfield's placeholder text in iOS
[self.userNameTxt setValue:[UIColor colorWithRed:41.0/255.0 green:91.0/255.0 blue:106.0/255.0 alpha:1.0] forKeyPath:@"_placeholderLabel.textColor"];
Easy and pain-free, could be an easy alternative for some.
_placeholderLabel.textColor
Not suggested for production, Apple may reject your submission.
[textfield setValue:your_color forKeyPath:@"_placeholderLabel.textColor"];
Hope it helps.
Note: Apple may reject (0.01% chances) your app as we are accessing private API. I am using this in all my projects since two years, but Apple didn't ask for this.
In Swift 3
import UIKit
let TEXTFIELD_BLUE = UIColor.blue
let TEXTFIELD_GRAY = UIColor.gray
class DBTextField: UITextField {
/// Tetxfield Placeholder Color
@IBInspectable var palceHolderColor: UIColor = TEXTFIELD_GRAY
func setupTextField () {
self.attributedPlaceholder = NSAttributedString(string:self.placeholder != nil ? self.placeholder! : "",
attributes:[NSForegroundColorAttributeName: palceHolderColor])
}
}
class DBLocalizedTextField : UITextField {
override func awakeFromNib() {
super.awakeFromNib()
self.placeholder = self.placeholder
}
}
Another option that doesn't require subclassing - leave placeholder blank, and put a label on top of edit button. Manage the label just like you would manage the placeholder (clearing once user inputs anything..)
