问题描述

在动画播放期间让按钮可以使用

在应用中的CAKeyframeAnimation，代码如下：

-(IBAction)start:(id)sender {    UIBezierPath *path = [UIBezierPath bezierPath];    [path moveToPoint:CGPointMake(600 150)];    [path addLineToPoint:CGPointMake(600 300)];    [path addLineToPoint:CGPointMake(450 300)];    [path addLineToPoint:CGPointMake(450 150)];    [path addLineToPoint:CGPointMake(600 150)];    CAKeyframeAnimation *move = [CAKeyframeAnimation animationWithKeyPath:@""position""];    move.path = path.CGPath;    move.duration = 6.0f;    move.repeatCount = 100;    [testButton.layer addAnimation:move forKey:@""move""];

怎么让动画进行的时候按钮也能用？试了好几种方法也没实现。

谢谢指教

解决方案

你要按钮在动画期间可以按，就需要自己的动画

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{    UITouch *t = [touches anyObject];    CGPoint location = [t locationInView:self.view];    for (UIButton *button in self.buttonsOutletCollection)    {        if ([button.layer.presentationLayer hitTest:location])        {            // This button was hit whilst moving - do something with it here            break;        }    }}
