我编写了以下代码以将手势识别器附加到多个图像视图。
[imageview1 setUserInteractionEnabled:YES];
[imageview1 setMultipleTouchEnabled:YES];
[imageview2 setUserInteractionEnabled:YES];
[imageview2 setMultipleTouchEnabled:YES];
[imageview3 setUserInteractionEnabled:YES];
[imageview3 setMultipleTouchEnabled:YES];
[imageview4 setUserInteractionEnabled:YES];
[imageview4 setMultipleTouchEnabled:YES];
[imageview5 setUserInteractionEnabled:YES];
[imageview5 setMultipleTouchEnabled:YES];
[imageview6 setUserInteractionEnabled:YES];
[imageview6 setMultipleTouchEnabled:YES];
UILongPressGestureRecognizer *gestureRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(gestureHandler:)];
gestureRecognizer.delegate = self;
[imageview1 addGestureRecognizer:gestureRecognizer];
[imageview2 addGestureRecognizer:gestureRecognizer];
[imageview3 addGestureRecognizer:gestureRecognizer];
[imageview4 addGestureRecognizer:gestureRecognizer];
[imageview5 addGestureRecognizer:gestureRecognizer];
[imageview6 addGestureRecognizer:gestureRecognizer];
我注意到两个问题！
所有图像视图都没有附加手势识别器！只有一个 imageview6（最后一个附加）具有手势识别器。这是苹果不允许的吗？
我在父视图的子视图中有所有这些图像视图。当我将这些直接添加到父视图（self.view）时，它可以工作，但仍然存在问题#1。当我在子视图（self.view.mysubview）中有这些图像视图时，它们都不能识别手势！
有人可以告诉我如何处理这些问题。
谢谢。
