iphone - 动画块相互干扰

我基本上在运行两个动画，一个接一个，似乎它们在相互干扰或以某种方式干扰UIView。我的代码在5.0 Simulator上运行良好，但在4.3 Simulator中出现问题。

基本上，我在屏幕上有一堆图像。触摸对象时，它会按比例放大：

[UIView animateWithDuration:0.1f
                          delay:0.0f
                        options:UIViewAnimationOptionCurveEaseIn
                     animations:^(void) {
                         //resizing the frame to make it bigger (original size is the new bigger size)
                         self.frame = CGRectMake(point.x - originalSize.width/2, point.y - originalSize.height/2 , originalSize.width, originalSize.height);

                     }
                     completion:^(BOOL complete){
                         //I have a showArrow method that draws an arrow to the superview to show the user where to place their image
                         [self performSelector:@selector(showArrow) withObject:nil afterDelay:1];
                     }];

该块完成后，它将运行showArrow，它仅显示一个反弹箭头：

[UIView animateWithDuration:0.5f
                          delay:0.0f
                        options:UIViewAnimationOptionAutoreverse | UIViewAnimationOptionRepeat
                     animations:^(void) {
                         self.arrow.frame = CGRectMake(arrowOrigin.origin.x, arrowOrigin.origin.y - 200, arrow.frame.size.width, arrow.frame.size.height);
                         self.arrow.alpha = 0.5;
                     }
                     completion:NULL];

因此，正如我所提到的，这在我的iPad和5.0模拟器上完美运行，但是在4.3中，一旦第一个动画运行，它似乎冻结了图像的平移手势或被触摸的能力。有什么想法吗？谢谢

最佳答案

尝试将UIViewAnimationOptionAllowUserInteraction掩码添加到options参数

[UIView animateWithDuration:0.1f
                      delay:0.0f
                    options:UIViewAnimationOptionCurveEaseIn |
                            UIViewAnimationOptionAllowUserInteraction
                 animations:^(void) {
                 // ...

在showArrow中：

[UIView animateWithDuration:0.5f
                      delay:0.0f
                    options:UIViewAnimationOptionAutoreverse |
                            UIViewAnimationOptionRepeat |
                            UIViewAnimationOptionAllowUserInteraction
                 animations:^(void) {
                 // ...
