UIButton с типомUIButtonTypeCustom вместоUILabel, Это похоже на ярлык и кликабельно.

Вы также можете рассмотреть сторонние реализации, такие как TTLabelThree20 а такжеНеобычные UILabels.

который будет работать что-то похожее, что вы хотите -

UILabel *myLabel = [[UILabel alloc] initWithFrame:];//Define label here as per needs
myLabel.userInteractionEnabled = YES;
UITapGestureRecognizer *gr = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(myAction:)];
[myLabel addGestureRecognizer:gr];
gr.numberOfTapsRequired = 1;
gr.cancelsTouchesInView = NO;
[self.view addSubview:myLabel];

Теперь для действий -

- (void) myAction: (UITapGestureRecognizer *) gr {
    // Define actions here
}

это будет полезно для you.try один раз и сообщите нам, если это будет полезно для вас.
