uitableview不响应选择

Question

我有一个我在主视图内添加到UIView的UITableView。该表加载自定义单元格并加载数据并正确响应滚动，但没有调用didSelectRowAtIndexPath。如果我将桌子移到其容器UIView外面，则可以调用delegate方法。

因此，它仅在容器视图内部时才无法工作，但是该视图具有userInteractionEnable = YES，并且表响应滚动。该表也设置为单个选择。

知道为什么它不会响应选择？预先感谢您的任何帮助

这是一些代码：

self.table.delegate = self;
self.table.dataSource = self;

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}
// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [self.classNames count];
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath     *)indexPath
{
    static NSString *MyIdentifier = @"MyIdentifier";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
    if(cell == nil)
    {
        [[NSBundle mainBundle] loadNibNamed:@"ClassCell" owner:self options:nil];
        cell = self.tvCell;
        self.tvCell = nil;
    }
    //Set up custom cell
    return cell;
}
//When cell is tapped
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSString *className = [NSString stringWithFormat:@"%@", [self.classNames objectAtIndex:indexPath.row]];
    if([[AppManager sharedManager] isPad])
    {
        ClassWork *controller = [[ClassWork alloc] initWithNibName:@"ClassWork_iPad" bundle:nil];
        controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
        controller.delegate = self;
        [controller setClassIndex:indexPath.row];
        [controller setClassTitle:[NSString stringWithString:className]];
        [self presentModalViewController:controller animated:YES];
    }
    else

            [self presentModalViewController:controller animated:YES];
        }
    }
}
//Delete Cell
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
    // If row is deleted, remove it from the list.
    if(editingStyle == UITableViewCellEditingStyleDelete)

        //Decrease by 1

        //Re-write

事实证明，有一个手势识别器吸吮所有触摸。我将其更改为在某些时间，然后消失了，现在表视图正常工作
