问题描述
我正在构建一个计算器应用程序,当我点击按钮时会出现一个简短的动画.问题是按钮在动画时没有响应,这让应用感觉迟钝.
I'm building a calculator app, when I tap on the buttons there is a short animation. The problem is the buttons do not respond while they are animating, which makes the app feel laggy.
我找到了一些针对 Objective-C 的解决方案:
I found some solutions for Objective-C using:
UIViewAnimationOptionAllowUserInteraction
但 Swift 3 没有,我的代码如下所示:
but nothing for Swift 3, my code looks like this:
func myButton () {
sender.layer.backgroundColor = firstColor
sender.setTitleColor(UIColor.white, for: UIControlState.normal)
UIView.animate(withDuration: 0.5) {
sender.layer.backgroundColor = secondColor
}
}
推荐答案
调用UIView的不同方法:
Call different method of UIView:
func myButton () {
sender.layer.backgroundColor = firstColor
sender.setTitleColor(UIColor.white, for: UIControlState.normal)
UIView.animate(withDuration: 0.5,
delay: 0.0,
options: .allowUserInteraction,
animations: {
sender.layer.backgroundColor = secondColor },
completion: nil)
}
