Hi all,

if you want to give inter letter spacing to any kind of text of button , label , textfields etc then you can follow this code.

First make attributed string :-

NSMutableAttributedString * title = [[NSMutableAttributedString alloc] initWithString:@"this is sample code to text this example"];
    [title addAttribute:NSForegroundColorAttributeName value:[UIColor lightGrayColor] range:NSMakeRange(0,22)];
    [title addAttribute:NSForegroundColorAttributeName value:[UIColor darkGrayColor] range:NSMakeRange(22,18)];
    [title addAttribute:NSKernAttributeName value:@(2.0) range:NSMakeRange(0,title.length)];

Now, assign attributed string to any object for example :-

//For UILabel

self.label.attributedText = title;

//For UIButton

[self.button setAttributedTitle:title forState:UIControlStateNormal];

//for UITextField

self.textField.attributedText = title;
