利用UIKit的UIView做动画的时候，当控件在运动的时候是不允许交互的。
解决方案：options 添加 UIViewAnimationOptionAllowUserInteraction
[UIView animateWithDuration:self.startDuration delay:0 options:UIViewAnimationOptionAllowUserInteraction animations:^{
self.frame = CGRectMake(self.pauseXRatio * screenSize.width, self.pauseYRatio * screenSize.height, self.giftWidth, self.giftHeight);
} completion:^(BOOL finished) {
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(self.pauseDuration * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
[UIView animateWithDuration:self.endDuration delay:0 options:UIViewAnimationOptionAllowUserInteraction animations:^{
self.frame = CGRectMake(self.endXRatio * screenSize.width, self.endYRatio * screenSize.height, self.giftWidth, self.giftHeight);
} completion:^(BOOL finished) {
NSLog(@"动画结束了");
}];
});
}];
但问题是：结果是只有在动画在中间停止的附近时，点击才会响应手势
终极解决方案：重写自定义 View 的 hitTest 方法
// 在自定义方法中重写下面这个方法
- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event
{
CGPoint locationPoint = [self.layer convertPoint:point toLayer:self.layer.presentationLayer];
CALayer *layer = self.layer.presentationLayer;
if(CGRectContainsPoint(layer.bounds, locationPoint)){
return self;
}
if (!self.layer.presentationLayer) {
return [super hitTest:point withEvent:event];
}
return nil;
}
