iOS 7: UITableViewController: Changing/Replacing Delete Button

Question

Disclaimer: I know it\'s not a best practice to tweak that kind of stuff because it may break as Apple decides to change its internal behaviour.

The reason you don't see the view inside layoutSubviews or willTransitionToState: is that the delete button view does not exist yet or it is not part of the view hierarchy yet. In order to "see" it you need to postpone a little the code that browses the view hierarchy, and by that allowing the OS to create/add the view in the meantime:

- (void)willTransitionToState:(UITableViewCellStateMask)state
{
    [super willTransitionToState:state];

    if (state & UITableViewCellStateShowingDeleteConfirmationMask)
    {
        [self performSelector:@selector(findDeleteButtonViewThroughViewHierarchy:) withObject:self.subviews afterDelay:0];
    }
}

Note this is a fragile solution since it is based on internal implementation of Apple that might change any time.
