问题描述
如何在 UIView 动画块中将 UIViewAnimationOptions 设置为 .Repeat:
How do I set the UIViewAnimationOptions to .Repeat in an UIView animation block:
UIView.animateWithDuration(0.2, delay:0.2 , options: UIViewAnimationOptions, animations: (() -> Void), completion: (Bool) -> Void)?)
推荐答案
Swift 3
和之前的差不多:
Swift 3
Pretty much the same as before:
UIView.animate(withDuration: 0.2, delay: 0.2, options: UIViewAnimationOptions.repeat, animations: {}, completion: nil)
除了您可以省略完整类型:
except that you can leave out the full type:
UIView.animate(withDuration: 0.2, delay: 0.2, options: .repeat, animations: {}, completion: nil)
你仍然可以组合选项:
UIView.animate(withDuration: 0.2, delay: 0.2, options: [.repeat, .curveEaseInOut], animations: {}, completion: nil)
斯威夫特 2
UIView.animateWithDuration(0.2, delay: 0.2, options: UIViewAnimationOptions.Repeat, animations: {}, completion: nil)
UIView.animateWithDuration(0.2, delay: 0.2, options: .Repeat, animations: {}, completion: nil)
UIView.animateWithDuration(0.2, delay: 0.2, options: [.Repeat, .CurveEaseInOut], animations: {}, completion: nil)
