Objective c 在UIScrollview中添加UIPangesture for UIButton以在all视图上移动

在我的项目中，我有底部的滚动条和顶部的表格。 在scrollview中，我添加了10个按钮。对于每个按钮，我都有平移手势在屏幕上移动。当按钮与table相交时，我将在tableview中添加一张图片

但是平移在卷轴内工作。如何使其在视图上移动

我的编码是：

downscroll=[[UIScrollView alloc]initWithFrame:CGRectMake(24, 635, 980, 100)];
downscroll.backgroundColor=[UIColor redColor];
downscroll.contentSize=CGSizeMake(990, 100);

[self.view addSubview:downscroll];

for(int i=1;i<=8;i++)
{
        b1=[UIButton buttonWithType:UIButtonTypeCustom];
        b1.frame=CGRectMake(30+px, 0, 80, 80);
       [b1 setImage:[UIImage imageNamed: [NSString stringWithFormat:@"Icon%i.png",i]]      forState:UIControlStateNormal];
     [downscroll addSubview:b1];
    // [self.view sendSubviewToBack:b1];
   // [self.view bringSubviewToFront:b1];

    [groupbutton addObject:b1];
     panRecognizer3= [[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(move:)];
    [b1 setUserInteractionEnabled:YES];
    b1.exclusiveTouch=YES;
    img.tag=i;
    [b1 addGestureRecognizer:panRecognizer3];

    px=px+120;
}

downscroll=[[UIScrollView alloc]initWithFrame:CGRectMake（246359801000）]；
downscroll.backgroundColor=[UIColor redColor]；
downscroll.contentSize=CGSizeMake（990100）；
[self.view addSubview:downscroll]；
对于（inti=1；i，以下是我在应用程序中使用的方法
在我的代码中，我遵循以下步骤

在UIPanGestureRecognizer起点中，我从scrollView将该按钮添加到self.view
使用
translationView
方法拖动按钮
3.在UIPanGestureRecognizer结束状态下，我将检查按钮是否在目标视图中掉落。如果是，请执行所需任务，否则请在scrollView中的相同位置添加按钮

`MoveControl` is a UIPanGestureRecognizer method



- (void)MoveControl:(UIPanGestureRecognizer *)recognizer
    {
        UIButton *vew=(UIButton *)[recognizer view];
        CGPoint newCenter = [recognizer translationInView:self.view];
        if (recognizer.state==UIGestureRecognizerStateBegan) {
            CGPoint point=vew.frame.origin;
            [vew setTitle:NSStringFromCGPoint(point) forState:UIControlStateSelected];
            CGRect rect=[self.view convertRect:[vew frame] fromView:[vew superview]];
            [vew setFrame:rect];
            [self.view addSubview:vew];
            CGPoint point1=vew.frame.origin;
            [vew setTitle:NSStringFromCGPoint(point1) forState:UIControlStateDisabled];
        }
        else
        {
            CGPoint oldcentre= CGPointFromString([vew titleForState:UIControlStateDisabled]);
            CGRect rect=vew.frame;
            CGPoint  origin=rect.origin;
            origin.x=(newCenter.x+oldcentre.x);
            origin.y=(newCenter.y+oldcentre.y);
            rect.origin=origin;
            vew.frame=rect;
            if (CGRectIntersectsRect(rect, [pageOriginalContainer frame])) {
                [YourTable setBackgroundColor:[UIColor lightGrayColor]];//Notifying that the tableView will accept the icon
            }
            else
            {
                [YourTable setBackgroundColor:[UIColor clearColor]];
            }
        }
        if (recognizer.state==UIGestureRecognizerStateEnded)
        {
            CGRect rect=[vew frame];
            if (CGRectIntersectsRect(rect, [pageOriginalContainer frame])) {
                  //your method of adding the Image to table
            }
            else//else part is means for if user dropped dragging somewhere else other than Table
            {
                CGPoint point=CGPointFromString([vew titleForState:UIControlStateSelected]);
                CGRect frame=vew.frame;
                frame.origin=point;
                vew.frame=frame;
                [pageCopyContainer addSubview:vew];
    //            [NSFileManager defaultManager]
            }
        }
    }
