In project development, we often encounter situations in which a uilabel uses different colors or different fonts to embody strings, and we can do this easily after iOS 6, and the official API gives us the attributedtext of the Uilabel class, Using strings of different colors and different fonts, we can use the Nsattributedtext and Nsmutableattributedtext classes to implement them.
Real code:
| 1234 |
@interfaceViewController : UIViewController@property (nonatomic, strong) IBOutletUILabel *attrLabel;- (IBAction)next:(id)sender;@end |
Add the following code to the. m file in the Viewdidload method:
| 123456789 |
self.title = @"For iOS 6 & later";NSMutableAttributedString*str = [[NSMutableAttributedStringalloc] initWithString:@"Using NSAttributed String"];[str addAttribute:NSForegroundColorAttributeNamevalue:[UIColor blueColor] range:NSMakeRange(0,5)];[str addAttribute:NSForegroundColorAttributeNamevalue:[UIColor redColor] range:NSMakeRange(6,12)];[str addAttribute:NSForegroundColorAttributeNamevalue:[UIColor greenColor] range:NSMakeRange(19,6)];[str addAttribute:NSFontAttributeNamevalue:[UIFont fontWithName:@"Arial-BoldItalicMT" size:30.0] range:NSMakeRange(0, 5)];[str addAttribute:NSFontAttributeNamevalue:[UIFont fontWithName:@"HelveticaNeue-Bold"size:30.0] range:NSMakeRange(6, 12)];[str addAttribute:NSFontAttributeNamevalue:[UIFont fontWithName:@"Courier-BoldOblique" size:30.0] range:NSMakeRange(19, 6)];attrLabel.attributedText = str; |
IOS displays different fonts and colors in Uilabel (IOS6 and later)
