Objective C:
yourLabelName.alpha = 1.0f;// yourLabelName
[UIView animateWithDuration:0.8 delay:0.0 options:
UIViewAnimationOptionCurveEaseInOut |
UIViewAnimationOptionRepeat |
UIViewAnimationOptionAutoreverse |
UIViewAnimationOptionAllowUserInteraction
animations:^{
yourLabelName.alpha = 0.0f;// yourLabelName
} completion:^(BOOL finished){
// Do nothing}];
Swift:
extension UILabel {
//MARK: StartBlink
func startBlink() {
UIView.animate(withDuration: 0.8,//Time duration
delay:0.0,
options:[.allowUserInteraction, .curveEaseInOut, .autoreverse, .repeat],
animations: { self.alpha = 0 },
completion: nil)
}
//MARK: StopBlink
func stopBlink() {
layer.removeAllAnimations()
alpha = 1
}
}
You can change the values to get different effects.
For example:- Changing animateWithDuration will set the blinking speed, repeat will give you continuous blinking effects.
Further you can use it on anything that inherits from UIView
example a UIButton
, UILabel
, custom view, etc.
Working 👍👍
