Question

这就是我想做的事情

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
    if (touch.view != self.myView) {
        NSLog(@"we went with no");
        //don't let anything that's not myView fire the gesture recognizer
        return NO;
    }
    NSLog(@"we went with yes");
    return YES;
}

问题是代码总是选择"we went with no"的路径，无论我在哪里实际挖掘。如何解决我的问题？

如果您在特定视图外点击时发现手势识别器操作正在触发，则应仔细检查是否正确添加了手势识别器。

[self.myView addGestureRecognizer:[[UIGestureRecognizer alloc] initWithTarget:self action:@selector(someAction:)]];

如果您仍然遇到错误的操作火灾，您可以检查触摸位置。

if (CGRectContainsPoint(self.myView.bounds, [gesture locationInView:self.myView]))

检查哪个视图发送gestureRecognizer
