Objective c 如何在uitableviewcell自定义单元格中设置UIView的大小

我在UITableView的自定义单元格中有一个UIButton，当拖动该按钮时，我必须在单元格中打开另一个视图，该视图最初位于单元格的最右角的自定义单元格中

- (UITableViewCell *)tableView:(UITableView *)_tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
 RecentCell *cell = (RecentCell*)[_tableView dequeueReusableCellWithIdentifier: [NSString stringWithFormat:@"%d-%d",indexPath.section,indexPath.row]];

    if (cell == nil) {
        cell = [[[NSBundle mainBundle] loadNibNamed:@"RecentCell" owner:self options:nil] lastObject];
    }

    [cell.TestButton addTarget:self action:@selector(ViewMovedTouchDragInside:withEvent:) forControlEvents:UIControlEventTouchDragInside];

return cell;

}

拖动按钮时调用此方法

- (IBAction) ViewMovedTouchDragInside:(id) sender withEvent:(UIEvent *) event
{
    UIControl *control = sender;

    UITouch *t = [[event allTouches] anyObject];
    CGPoint pPrev = [t previousLocationInView:control];
    CGPoint p = [t locationInView:control];

    CGPoint center = control.center;
    center.x += p.x - pPrev.x;
    CGPoint hitPoint = [sender convertPoint:CGPointZero toView:self.tableView];
    NSIndexPath *hitIndex = [self.tableView indexPathForRowAtPoint:hitPoint];
    RecentCell * swipedCell = (RecentCell*)[self.tableView cellForRowAtIndexPath:hitIndex];
       //Drag Button on left hand side
        if (control.frame.origin.x<0) {


        swipedCell.MessageView.Frame=CGRectMake(320.0+control.frame.origin.x,0,control.frame.origin.x,swipedCell.MessageView.frame.size.height);

       NSLog(@"*****%f*****%f****%f****%f",swipedCell.MessageView.frame.origin.x,swipedCell.MessageView.frame.origin.y,swipedCell.MessageView.frame.size.width,swipedCell.MessageView.frame.size.height);
            }
            else{
               swipedCell.CallImage.frame=CGRectMake(0.0,0,control.frame.origin.x,cell.CallImage.frame.size .height);
            }
        }

-（iAction）ViewMovedTouchDragInside:（id）发送方withEvent:（UIEvent*）事件
{
UIControl*控制=发送方；
UITouch*t=[[event AllTouchs]anyObject]；
CGPoint pPrev=[t previousLocationInView:对照]；
CGP点=[t位置视图：对照]；
CGPoint center=control.center；
center.x+=p.x-pPrev.x；
CGPoint hitPoint=[sender-convertPoint:CGPointZero-toView:self.tableView]；
NSIndexPath*hitIndex=[self.tableView indexPathForRowAtPoint:hitPoint]；
RecentCell*swipedCell=（RecentCell*）[self.tableView cellForRowAtIndexPath:hitIndex]；
//左侧的拖动按钮
如果（control.frame.origin.x）选中此演示，将对象保留在scrollView中，只需左右拖动即可
