In IOS 6 you could change the font, textColor, and textAlignment for particular word through attributedText you could find the documentation for this here

http://developer.apple.com/library/ios/#documentation/uikit/reference/UITextView_Class/Reference/UITextView.html

Same question is answered in stackoverflow the link of the question is as follows

I think you are looking for this thing, hope it will work for you.

For a string like firstsecondthid, you can do like this. With first written in RED, second in GREEN and third in BLUE.

Example code:

NSMutableAttributedString * string = [[NSMutableAttributedString alloc] initWithString:@"firstsecondthird"];  
[string addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0,5)];  
[string addAttribute:NSForegroundColorAttributeName value:[UIColor greenColor] range:NSMakeRange(5,6)];  
[string addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor] range:NSMakeRange(11,5)];

  • I used this code. But i am getting the error message, 'use of undeclared identifier NSForegroundColorAttributeName'. What will i do? – AKS Jun 24 '13 at 08:49
  • Replace this [string addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0,5)]; with [string addAttribute:(NSString*)kCTForegroundColorAttributeName value:(id)[[UIColor redColor] CGColor] range:NSMakeRange(0,5)]; – Shahab Qureshi Jun 24 '13 at 08:58
  • How can we set this NSMutableAttributedString to a label. I am very sorry if my question is wrong. I am a beginner in IOS. I used the code myLabel.text = (NSString*)string; But i am getting crash. – AKS Jun 24 '13 at 09:15
  • Very simple Just do this self.attributedLabel.attributedText = string; – Shahab Qureshi Jun 24 '13 at 09:17

As the previous answers have mentioned, you need to use an NSAttributedString to store formatted text.

However, native support in iOS for attributed strings in UILabels was only introduced in iOS 6.

If you want to support iOS 5 and below, there are many libraries around for displaying an attributed string. I would recommend using TTTAttributedLabel.
