Ios 如何更改UITableViewCell的宽度？

我正在开发一个具有SwipeGesture的UITableView。 滑动时，单元格应向左滑动，设置为320的对象应出现

将它们放置在UITableViewCell的contentView中，并在contentView上制作动画，将帧更改为x=-320，这样就可以工作。

UITableView在将单元格添加到表视图时更改单元格的帧。如果要更改单元格的宽度，应更改表的宽度，或更改单元格中contentView的宽度

实现这一点的更好方法是子类化UITableViewCell并重写其-setFrame:方法，如下所示：

试试这个：

- (void)setFrame:(CGRect)frame  
{
  frame.origin.x += inset;
  frame.size.width -= 2 * inset;
  [super setFrame:frame];
}

请尝试下面的代码

    // Create the swipe view

    //Change the frame as per your requirement

   UIView* _swipeView = [[UIView alloc] initWithFrame:CGRectMake(5, 5, 10, 70)];       
    //setting the background
    [_swipeView setBackgroundColor:[UIColor redColor]];

    [_swipeView setTag:1896];
    [cell.contentView addSubview:_swipeView];        

    // Create the gesture recognizers
    UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(didSwipeRightInCell:)];
    [swipeRight setDirection:UISwipeGestureRecognizerDirectionRight];

    UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(didSwipeLeftInCell:)];
    [swipeLeft setDirection:UISwipeGestureRecognizerDirectionLeft];

    [cell addGestureRecognizer:swipeRight];
    [cell addGestureRecognizer:swipeLeft];

希望这有帮助。

尝试阅读本教程。这将消除您的所有疑问和问题。获取错误UITableViewController的无可见界面声明选择器setFrame：否则，您必须在单元格上添加视图，并且当您要向左滑动时，您必须从右向左设置该视图的动画
