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

In objective-C, go ahead and create a category method off of the UIView class.

- (void)removeAllSubviews
{
    for (UIView *subview in self.subviews)
        [subview removeFromSuperview];
}
