我有以下代码想要淡入和淡出 UILabel。但我只想让它重复淡入淡出 5 次。我的问题是如何设置动画只重复 3 次？
func savingIcon(){
Loading.hidden=false
UIView.animateWithDuration(1.0,
delay: 0.0,
options: [ .CurveEaseInOut],
animations: {
self.Loading.alpha=0.0;
self.Loading.alpha=1.0;
self.Loading.alpha=0.0;
self.Loading.alpha=1.0;
self.Loading.alpha=0.0;
},
completion: { finished in
print("Save done")
self.Loading.hidden=true
})
}
最佳答案
如果你想重复你的动画 block 5 次，尝试这样做:
UIView.animateWithDuration(1.0,
delay: 0.5,
options: [ .CurveEaseInOut, .Repeat],
animations: {
UIView.setAnimationRepeatCount(5)
self.Loading.alpha=0.0;
self.Loading.alpha=1.0;
self.Loading.alpha=0.0;
self.Loading.alpha=1.0;
self.Loading.alpha=0.0;
},
completion: { finished in
print("Save done")
self.Loading.hidden=true
})
