我有一个文本字段,用户应该输入信息.以及将用户指向文本字段的标签(如提示).
文本标签上有重复的动画.创建者：
override func viewDidLoad() {
super.viewDidLoad()
textInput.addTarget(self,action: #selector(CalculatorViewController.removeAnimation(_:)),forControlEvents: UIControlEvents.TouchDown)
self.hintLabel.alpha = 0.0
UIView.animateWithDuration(1.5,delay: 0,options: .Repeat,animations: ({
self.hintLabel.alpha = 1.0
}),completion: nil
)
func removeAnimation(textField: UITextField) {
view.layer.removeAllAnimations()
self.view.layer.removeAllAnimations()
print("is it working?!")
}
应根据文件工作.
解决方法
//Just remove the animation from the label. It will Work
func remove()
{
self.hintLabel.layer.removeAllAnimations()
self.view.layer.removeAllAnimations()
self.view.layoutIfNeeded()
}
更新：
如果你想要核,你也可以这样做：
func nukeAllAnimations() {
self.view.subviews.forEach({$0.layer.removeAllAnimations()})
self.view.layer.removeAllAnimations()
self.view.layoutIfNeeded()
}
