iOS 滑动检测仅适用于 1 个 UITableViewCell？

Question

我正在尝试在 2 个表格单元格上添加滑动检测。但是，到目前为止，滑动检测仅适用于一个表格单元格。

以下是我的部分代码:

- (void)viewDidLoad {

     [super viewDidLoad];
     numbers = [[NSMutableArray alloc]init];
     tableCellTrash = [[NSMutableArray alloc]init];

     mSwipeRecognizer= [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(removeCell:)];
     [mSwipeRecognizer setDirection:( UISwipeGestureRecognizerDirectionLeft | UISwipeGestureRecognizerDirectionRight)];
}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"CustomPlaceCell";
    CustomPlaceCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil) {
        cell = [[[NSBundle mainBundle] loadNibNamed:@"CustomPlaceCell" owner:nil options:nil] objectAtIndex:0];
        [numbers addObject:cell];
        [cell addGestureRecognizer:mSwipeRecognizer];
        NSLog(@"Cell");
    }

    return cell;
}

-(void)removeCell:(UISwipeGestureRecognizer *)aSwipeGestureRecognizer{
    NSLog(@"Swipe Detected!");
}

任何人都知道为什么滑动检测仅适用于其中一个单元格？

一个 UIGestureRecognizer只能与单个 View 关联。您应该为每个单元格设置不同的手势识别器。您可以将 GestureRecognizer 创建移动到

     if (cell == nil) {
        cell = [[[NSBundle mainBundle] loadNibNamed:@"CustomPlaceCell" owner:nil options:nil] objectAtIndex:0];
        [numbers addObject:cell];

        UISwipeGestureRecognizer *swipeRecognizer= [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(removeCell:)];
        [swipeRecognizer setDirection:( UISwipeGestureRecognizerDirectionLeft | UISwipeGestureRecognizerDirectionRight)];     

        [cell addGestureRecognizer:swipeRecognizer];

        NSLog(@"Cell");
    }
