Ios 将UILongPressGestureRecognitor添加到自定义UITableViewCell内的UIButton

我有一个带有各种IBoutlet的自定义单元格，但我想在一个按钮上添加一个UILongPressGestureRecognitor，用于长按手势。这是我的代码（顺便说一句，插座连接正确，按钮的

iAction

方法调用正确）：

---

问题是

handleLongPress手势：

方法从未调用。

长按手势识别器应是控制器上的属性，而不是视图（MyCustomCell）。将属性移到MyViewController上，然后重试。我猜当它在MyCustomCell中排队和退队时，会发生一些奇怪的事情

重用的对象（单元）应该是轻量级的。在这种情况下，LongPressGestureRecognitor的目标是视图控制器，非常讨厌。

试试这个

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UILongPressGestureRecognizer *LongPress=[[UILongPressGestureRecognizer alloc]initWithTarget:self action:@selector(handleLongPressGestures:)];
    LongPress.minimumPressDuration = 1.0f;
    LongPress.allowableMovement = 300.0f;
    [cell.myButton addGestureRecognizer:LongPress];
}

- (void)handleLongPressGestures:(UIGestureRecognizer *)recognizer
{
      if ([recognizer.view isKindOfClass:[UIButton class]]){
         if (recognizer.state == UIGestureRecognizerStateBegan){
             NSLog(@"Long press began");
         } 
         else if (recognizer.state = UIGestureRecognizerStateEnded)
         {
             NSLog(@"Long press ended");
         }
      }
 }

这样试试看

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *identifier = @"MyCell";
    MyCustomCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier forIndexPath:indexPath];
    if (!cell){
        cell = [[MyCustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
    }
    if ([[cell gestureRecognizers] count]<1) {
        UILongPressGestureRecognizer *longPressGestureRecognizer;
        longPressGestureRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPressGestures:)];
        longPressGestureRecognizer.minimumPressDuration = 1.0f;
        longPressGestureRecognizer.allowableMovement = 300.0f;
        longPressGestureRecognizer.delegate = self;
        [cell.myButton addGestureRecognizer:cell.longPressGestureRecognizer];
    }
}

-（UITableViewCell*）tableView:（UITableView*）tableView cellForRowAtIndexPath:（NSIndexPath*）indexPath
{
静态NSString*标识符=@“MyCell”；
MyCustomCell*cell=[tableView dequeueReusableCellWithIdentifier:identifier forIndexPath:indexPath]；
如果（！单元格）{
cell=[[MyCustomCell alloc]initWithStyle:UITableViewCellStyleDefault重用标识符：标识符]；
}
如果（[[cell gestureRecognizers]count]我也尝试将
LongPress GestureRecognizer
用作视图控制器中的属性，但没有成功。
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *identifier = @"MyCell";
    MyCustomCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier forIndexPath:indexPath];
    if (!cell){
        cell = [[MyCustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
    }
    if ([[cell gestureRecognizers] count]<1) {
        UILongPressGestureRecognizer *longPressGestureRecognizer;
        longPressGestureRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPressGestures:)];
        longPressGestureRecognizer.minimumPressDuration = 1.0f;
        longPressGestureRecognizer.allowableMovement = 300.0f;
        longPressGestureRecognizer.delegate = self;
        [cell.myButton addGestureRecognizer:cell.longPressGestureRecognizer];
    }
}
