touchesEnded未调用

Question

我的视图中有一个自定义表名tbltask，触摸开始和触摸移动方法我动态创建标签。

 -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{


    [super touchesBegan:touches withEvent:event];



     self.scrollEnabled=NO;
    CGPoint point = [[touches anyObject] locationInView:[self superview]]; 
    CGPoint pointtask=[[touches anyObject] locationInView:self];
    NSIndexPath *indexPath = [self indexPathForRowAtPoint:pointtask];
    rowid=indexPath.row;




      app.sublable=[[UILabel alloc] initWithFrame:CGRectMake((point.x)-145, (point.y)-50, 300, 40)];
    app.sublable.textAlignment=UITextAlignmentRight;
    messagedrag=[app.arraddtask objectAtIndex:rowid];
    app.sublable.text=[NSString stringWithFormat:@" %@",messagedrag.msgsubject];
    app.sublable.backgroundColor=[UIColor colorWithPatternImage:[UIImage imageNamed:@"black.png"]];  

    app.sublable.layer.cornerRadius=8.0;
      app.sublable.layer.borderWidth=4;
     app.sublable.layer.borderColor=[[UIColor lightGrayColor] CGColor];
       app.sublable.textColor=[UIColor whiteColor];

    UIFont *f = [UIFont fontWithName:@"Verdana-Bold" size:16];
    app.sublable.font = f;
    [app.sublable setTextAlignment:UITextAlignmentLeft];

    [self.superview addSubview:app.sublable];



}

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    [super touchesMoved:touches withEvent:event];

    if(app.sublable!=nil)
    {

        [app.sublable removeFromSuperview];

    }
    CGPoint point = [[touches anyObject] locationInView:[self superview]]; 
    NSIndexPath *indexPath = [self indexPathForRowAtPoint:point];

    NSLog(@"............super %f",[self superview].frame.origin.y);

    app.sublable=[[UILabel alloc] initWithFrame:CGRectMake((point.x)-145, (point.y)-50, 300, 40)];
    app.sublable.textAlignment=UITextAlignmentRight;
    messagedrag=[app.arraddtask objectAtIndex:rowid];
    app.sublable.text=[NSString stringWithFormat:@" %@",messagedrag.msgsubject];

     app.sublable.backgroundColor=[UIColor colorWithPatternImage:[UIImage imageNamed:@"black.png"]];  

    app.sublable.layer.borderWidth=4;
    app.sublable.layer.borderColor=[[UIColor lightGrayColor] CGColor];
    app.sublable.layer.cornerRadius=8.0;
    app.sublable.textColor=[UIColor whiteColor];
       UIFont *f = [UIFont fontWithName:@"Verdana-Bold" size:16];
    app.sublable.font = f;
    [app.sublable setTextAlignment:UITextAlignmentLeft];

    [self.superview addSubview:app.sublable];






}

导致了这一点。

所以当我触摸tbltask touchBegan方法开始工作并创建一个带有主题的标签时会在superview中写入，这是主视图，其中tbltask就在那里你可以看到。（底部是表任务）

现在当我调用touchesEnded方法::

 - (void)touchesEnded:(NSSet*)touches withEvent:(UIEvent*)event
    {
        //<my stuff>

        [super touchesEnded:touches withEvent:event];
        NSString *taskname=[[NSString alloc] init];
         self.scrollEnabled=YES;
        if(app.sublable!=nil)
        {
           taskname=app.sublable.text;
            [app.sublable removeFromSuperview];
        }

        [taskdelegate droptask:self strtask:taskname];


    }

这个问题放在上面
它运行正常。但是当我从左到右或从右到左触摸tbltask时发生了一些事情，并且没有调用触摸结束方法，因此不会从视图中移除sublable。就像这样......

我在这做错了什么...... 是的，我会在桌面触摸时调用触摸事件，您会注意到。 请帮我解决这个问题...... 在此先感谢。
