我希望我的按钮能够持续动画,直到用户触摸它为止,这里是代码
func animate() {
UIView.animateWithDuration(1, animations: { () -> Void in
self.animation.transform = CGAffineTransformMakeScale(0.8,0.8)
})
UIView.animateWithDuration(0.5, animations: { () -> Void in
self.animation.transform = CGAffineTransformMakeScale(1,1)
})
}
使用NSTimer
timer = NSTimer.scheduledTimerWithTimeInterval(0.5, target: self, selector: Selector("animate"), userInfo: nil, repeats: true)
动画效果很好,但我无法找到使其可点击的方法。

您需要使用较长形式的animateWithDuration,它采用options参数并指定UIViewAnimationOptionAllowUserInteraction选项。像这样:
UIView.animateWithDuration(1,
delay: 0,
options: .AllowUserInteraction,
animations:
{ () -> Void in
self.animation.transform = CGAffineTransformMakeScale(0.8,0.8)
}
completion: nil
);
(我的斯威夫特有点生疏,但无论如何这都是想法。)
