Is there anyway to change the character spacing (track) on UILabel text using Interface Builder? If not, is there a way to do it programmatically on an existing UILabel that
try this!!
create CustomLabel class
@interface CustomLabel : UILabel
@property (assign, nonatomic) CGFloat myLineSpacing;
@end
@implementation CustomLabel
- (void)setMyLineSpacing:(CGFloat)myLineSpacing {
_myLineSpacing = myLineSpacing;
self.text = self.text;
}
- (void)setText:(NSString *)text {
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
paragraphStyle.lineSpacing = _myLineSpacing;
paragraphStyle.alignment = self.textAlignment;
NSDictionary *attributes = @{NSParagraphStyleAttributeName: paragraphStyle};
NSAttributedString *attributedText = [[NSAttributedString alloc] initWithString:text
attributes:attributes];
self.attributedText = attributedText;
}
and set runtime attribute

Note this is actually line spacing (also called leading .. in the very old days (pre-digital) you'd put lead (the metal) between lines to increase the gap between lines. For spacing between letters, that is called kerning .. here's how to do kerning https://stackoverflow.com/a/21141156/294884
