How to Check If UITableViewCell Contains UIView

Question

I am adding subview to UITableViewCell i.e

UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault` reuseIdentifier:cellIdentifier];

Here _cellBackgroundView belongs to UIView.

[cell.contentView addSubview:_cellbackground];

I want to check by the help of isDescendantOfView if it contains _cellbackground, but I am getting warning.

if (![_cellbackground isDescendantOfView:[cell subviews]]) {
    [cell.contentView addSubview:_cellbackground];

}
else{
    [_cellbackground removeFromSuperview];
}

references Check if a subview is in a view

Please help

You say you are getting warning. What does the warning say ? — Niko, May 31 '16 at 08:16

[cell subviews] return array , but you need to give UIView as input parameter for isDescendantOfView: method , try like this it will work

if (![_cellbackground isDescendantOfView:cell.contentView]) {
    [cell.contentView addSubview:_cellbackground];
}
else {
    [_cellbackground removeFromSuperview];
}
