Remove all subviews?

Question

When my app gets back to its root view controller, in the viewDidAppear: method I need to remove all subviews.

How can I do this?

Answer 1

Get all the subviews from your root controller and send each a removeFromSuperview:

NSArray *viewsToRemove = [self.view subviews];
for (UIView *v in viewsToRemove) {
    [v removeFromSuperview];
}
