Question

我有这段代码：

UISwipeGestureRecognizer *recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(rightSwipeHandle:)];
[recognizer setNumberOfTouchesRequired:1];
[view1 addGestureRecognizer:recognizer];
[view2 addGestureRecognizer:recognizer];
[view3 addGestureRecognizer:recognizer];
[recognizer release];

- (void)rightSwipeHandle:(UISwipeGestureRecognizer*)gestureRecognizer{ //do something}

它只识别在view3中滑动，为什么？我该如何解决这个问题？我应该为每个视图进行新的swipegesture吗？但我有20个观点。

如果您有20个视图，它们可能存储在数组或其他内容中？如果是的话，你试过这样的事吗？

 for (unsigned i = 0; i < [yourViewsArray count]; i++){
    UIView *view = [yourViewsArray objectAtIndex:i]; 
    UISwipeGestureRecognizer *recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(rightSwipeHandle:)];
    [recognizer setNumberOfTouchesRequired:1];
    [view addGestureRecognizer:recognizer];
    [recognizer release];
 }

使用此功能，您可以为每个视图添加新的识别器
