Changing the color of UITableViewCellDeleteConfirmationControl(Delete Button) in UITableViewCell

Question

Currently I'm trying to customize delte button in UITableViewCell. Now I've got something like that:

Now, all what I need is to change the color of this button, I don't want to change the behavior, or to make it absolutelly custom. I'm sure that it is possible, without creating your own controls for deleting rows in UITableView.

This my code:

- (void)layoutSubviews
{
    [super layoutSubviews];

    for (UIView *subview in self.subviews) {
        if ([NSStringFromClass([subview class]) isEqualToString:@"UITableViewCellDeleteConfirmationControl"]) {
            UIView *deleteButtonView = (UIView *)[subview.subviews objectAtIndex:0];
            deleteButtonView.backgroundColor = [UIColor greenColor];
        }
    }
}

How could I do this?

Thanks in advance!

Answer 1

UITableViewCellDeleteConfirmationControl is not a public class and you cannot easily change its appearance.

In order to do so I believe you'd have to iterate through the subviews of the cell and change its properties:

for (UIView *subview in self.subviews) {
    if ([NSStringFromClass([subview class]) isEqualToString:@"UITableViewCellDeleteConfirmationControl") {
        // Set the background using an image.
    }
}

Of course, you should be wary of doing this sort of thing since its rather fragile. I'd suggest rolling your own instead.

I'd suggest submitting a bug report to Apple to request the ability to edit this more easily.

In the UITableViewCell subclass:

- (UIView*)recursivelyFindConfirmationButtonInView:(UIView*)view
{
    for(UIView *subview in view.subviews) {
        if([NSStringFromClass([subview class]) isEqualToString:@"UITableViewCellDeleteConfirmationButton"]) return subview;
        UIView *recursiveResult = [self recursivelyFindConfirmationButtonInView:subview];
        if(recursiveResult) return recursiveResult;
    }
    return nil;
}

-(void)overrideConfirmationButtonColor
{
    dispatch_async(dispatch_get_main_queue(), ^{
        UIView *confirmationButton = [self recursivelyFindConfirmationButtonInView:self];
        if(confirmationButton) confirmationButton.backgroundColor = [UIColor orangeColor];
    });
}

Then in the UITableViewDelegate:

-(void)tableView:(UITableView *)tableView willBeginEditingRowAtIndexPath:(NSIndexPath *)indexPath
{
    <#Your cell class#> *cell = (<#Your cell class#>*)[self.tableView cellForRowAtIndexPath:indexPath];
    [cell overrideConfirmationButtonColor];
}

This works in iOS 7.1.2
