ios-在動畫播放期間讓按鈕可以使用

在動畫播放期間讓按鈕可以使用

在應用中的CAKeyframeAnimation，代碼如下：

-(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"];

怎麼讓動畫進行的時候按鈕也能用？試了好幾種方法也沒實現。

謝謝指教

最佳回答：

你要按鈕在動畫期間可以按，就需要自己的動畫

- (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;
        }
    }
}
