Question

正如这个问题的标题所说，我需要创建一个视图，当需要点击或按住它时需要采取行动。这意味着我必须添加UITapGestureRecognizer和UILongPressGestureRecognizer。我已经尝试过了。它以某种方式将我重定向到我需要去的屏幕，但它影响了它的后退按钮。受其意义影响，它会返回默认文本“Item”，并且无法执行指定的操作。

Answer 1

是的，您可以在一个视图中添加这两个手势。请参阅以下代码

UITapGestureRecognizer *singleTapRecognizer = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(didTap:)];
    singleTapRecognizer.numberOfTapsRequired = 1;
    singleTapRecognizer.delegate = self;
    [self.view addGestureRecognizer:singleTapRecognizer];
UILongPressGestureRecognizer *longPressRecognizer = [[UILongPressGestureRecognizer alloc]initWithTarget:self action:@selector(didLongPress:)];
    [longPressRecognizer setDelegate:self];
    longPressRecognizer.allowableMovement = 1.0f;
    longPressRecognizer.minimumPressDuration = 2.0;
    [self.view addGestureRecognizer:longPressRecognizer];

Answer 2

正如我在评论中提到的，你可以这样做，这里有一些代码可以帮助你。

UITapGestureRecognizer * recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];
        recognizer.delegate = self;
        [view addGestureRecognizer:recognizer];

UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc]
                                             initWithTarget:self 
                                             action:@selector(handleLongPress:)];
        longPress.minimumPressDuration = 2.0;
        [view addGestureRecognizer:longPress];
