Multicolor on UILabel in iOS 5

Question

I have a UILabel in which I need to display two different colored strings: Below is my code:

NSMutableAttributedString *text = [[NSMutableAttributedString alloc] initWithAttributedString: lbl_question.attributedText];

[text addAttribute: NSForegroundColorAttributeName value: [UIColor colorWithRed:52.0f/255.0f green:104.0f/255.0f blue:165.0f/255.0f alpha:1.0f] range: NSMakeRange(0,[result integerValue]+1)];

[text addAttribute: NSForegroundColorAttributeName value: [UIColor colorWithRed:75.0f/255.0f green:75.0f/255.0f blue:75.0f/255.0f alpha:2.0f] range: NSMakeRange([result integerValue]+1,[strq length])];
[lbl_question setAttributedText: text];

In iOS 6 it works fine but in ios 5 and earlier versions the two strings just got ovelapped everytime. also i want to get width according to text and font. increase height according to their text.

I am sure there has to be solution...Please help me out with this....

Answer 1

You can do this using NSMutableAttributedString. This will work in ios 6,ios 7 and ios 8 also.

Note that NSMakeRange(startin gpoint counting from zero,number of character);

    NSMutableAttributedString * string = [[NSMutableAttributedString alloc] initWithString:@"RedGreenBlue"];
    [string addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0,3)];
    [string addAttribute:NSForegroundColorAttributeName value:[UIColor greenColor] range:NSMakeRange(3,5)];
    [string addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor] range:NSMakeRange(8,4)];   
    lable.attributedText=string;
