UITextField set placeholder color as dark in iOS

Question

I have tried to set UITextField \"Placeholder\" color as dark.

NSAttributedString * search = [[NSAttributedString alloc] initWithSt         


        

Answer 1

To make it future-proof and completely customizable (color, font, size, etc.), I would just add a UILabel on top and hide/show it manually according to the UITextField contents.

Just make sure to set the label's userInteractionEnabled to NO.

Answer 2

Try this

 [textField setValue:[UIColor blackColor] forKeyPath:@"_placeholderLabel.textColor"];

Answer 3

As suggested by Apple, subclassing UITextField and overriding - (void)drawPlaceholderInRect:(CGRect)rect is the way to go:

- (void)drawPlaceholderInRect:(CGRect)rect { 
    UIColor *colour = [UIColor lightGrayColor]; 
    if ([self.placeholder respondsToSelector:@selector(drawInRect:withAttributes:)]) 
    { // iOS7 and later 
        NSDictionary *attributes = @{NSForegroundColorAttributeName: colour, NSFontAttributeName: self.font}; 
        CGRect boundingRect = [self.placeholder boundingRectWithSize:rect.size options:0 attributes:attributes context:nil]; 
        [self.placeholder drawAtPoint:CGPointMake(0, (rect.size.height/2)-boundingRect.size.height/2) withAttributes:attributes]; } 
    else { // iOS 6 
        [colour setFill]; 
        [self.placeholder drawInRect:rect withFont:self.font lineBreakMode:NSLineBreakByTruncatingTail alignment:self.textAlignment]; 
    } 
 }

Answer 4

Overriding the drawPlaceholderInRect: method to draw our own placeholder text.

- (void)drawPlaceholderInRect:(CGRect)rect
{
    UIColor *colour = [UIColor darkColor];
    
    if ([self.placeholder respondsToSelector:@selector(drawInRect:withAttributes:)]) {
        // iOS7 and later
        NSDictionary *attributes = @{NSForegroundColorAttributeName: colour, NSFontAttributeName: self.font};
        CGRect boundingRect = [self.placeholder boundingRectWithSize:rect.size options:0 attributes:attributes context:nil];
        [self.placeholder drawAtPoint:CGPointMake(0, (rect.size.height/2)-boundingRect.size.height/2) withAttributes:attributes];
    }
    else {
        // iOS 6
        [colour setFill];
        [self.placeholder drawInRect:rect withFont:self.font lineBreakMode:NSLineBreakByTruncatingTail alignment:self.textAlignment];
    }
}

OR

This case, likely crash if the internal variable changes in the future

Programmatically:

  [self.MyTextField setValue:[UIColor blackColor] forKeyPath:@"_placeholderLabel.textColor"];

In UIStoryBoard:

EDIT: Playing with UITextFiled delegates. its like a tricky:

-(void)viewDidLoad{
  self.mytxtField.text = @"PlaceholderText";
  self.mytxtField.delegate = self;
   self.mytxtField.textColor = [UIColor darkGrayColor];

}

-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField{
           if ([self.mytxtField.text isEqualToString: @"PlaceholderText"]) {
             self.mytxtField.text = @"";
             self.mytxtField.textColor = [UIColor blackColor]; 
        }
    }


-(void)textFieldDidEndEditing:(UITextField *)textField{
      if ([self.mytxtField.text length]<1) {
            self.mytxtField.text =@"PlaceholderText";
            self.mytxtField.textColor = [UIColor darkGrayColor]; 

        }

For iOS8, you can take advantage of @IBDesignable & @IBInspectable.

Here is a UITextField subclass in Swift which lets you set the placeholder color in Interface Builder and see the result instantly:

@IBDesignable class EDTextField: UITextField {
    @IBInspectable var placeholderColor: UIColor = UIColor.whiteColor() {
        didSet {
            if let placeholder = self.placeholder {
                let attributes = [NSForegroundColorAttributeName: placeholderColor]
                attributedPlaceholder = NSAttributedString(string: placeholder, attributes: attributes)
            }
        }
    }
}

Answer 6

Its very simple....

Try this to change placeholder text color..

UIColor *color = [UIColor blackColor];
textField.attributedPlaceholder = [[NSAttributedString alloc] initWithString:placeholderText attributes:@{NSForegroundColorAttributeName: color}];
