IOS:手势获得更多浏览量

Question

我有这个代码:

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}

它只在 view3 中识别滑动，为什么？我该如何解决这个问题？我应该为每个 View 做一个新的滑动手势吗？但我有 20 次观看。

如果您有 20 个 View ，它们可能存储在数组或其他东西中？如果是，您尝试过这样的方法吗？

 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];
 }

这样你就可以为每个 View 添加一个新的识别器
