Question

我在cellForRowAtIndexPath

中添加了此代码

UISwipeGestureRecognizer *gestureR = [[UISwipeGestureRecognizer alloc]
                                             initWithTarget:self action:@selector(handleSwipeFrom:)];
        [gestureR setDirection:UISwipeGestureRecognizerDirectionRight];//|UISwipeGestureRecognizerDirectionRight)];
        [cell addGestureRecognizer:gestureR];

它工作正常。但我想要UISwipeGestureRecognizerDirectionLeft所以像这样添加

[gestureR setDirection:UISwipeGestureRecognizerDirectionLeft|UISwipeGestureRecognizerDirectionRight)];

当我检查方向和状态时，我总是得到3 = 3

- (void)handleSwipeFrom:(UISwipeGestureRecognizer *)recognizer {    

    NSLog(@"%d = %d",recognizer.direction,recognizer.state);
}

如果我只申请一个手势，它可以正常工作。我试着逐个添加两个手势。但它只会响应一个手势。

如何添加第二个手势。我直接将一个手势添加到TableView另一个手势，但现在使用。

Answer 1

试试这个

UISwipeGestureRecognizer* gestureR;
gestureR = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom)] autorelease];
gestureR.direction = UISwipeGestureRecognizerDirectionLeft;
[view addGestureRecognizer:gestureR];

gestureR = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom)] autorelease];
gestureR.direction = UISwipeGestureRecognizerDirectionRight; // default
[view addGestureRecognizer:gestureR];

如果您想在左右滑动中处理不同的功能，只需更改选择器。

Answer 2

如果使用

，最好不要两次分配

UISwipeGestureRecognizer* recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe:)];
[recognizer setDirection:UISwipeGestureRecognizerDirectionLeft+UISwipeGestureRecognizerDirectionRight];
[cell addGestureRecognizer:recognizer];

并在动作中获取滑动方向：

-(void)handleSwipe:(UISwipeGestureRecognizer *) sender 
{
    if (sender.direction == UISwipeGestureRecognizerDirectionLeft) 
    {
    //do something
    }
    else //if (sender.direction == UISwipeGestureRecognizerDirectionRight) 
    {
  //do something
     }
}

Answer 3

我知道你问这个问题已经过了很久了。但请在您的问题中再次阅读以下行。 [gestureR setDirection:UISwipeGestureRecognizerDirectionRight|UISwipeGestureRecognizerDirectionRight)];

您是否意识到您添加了UISwipeGestureRecognizerDirectionRight。两次！！
