Get to UIViewController from UIView?

Question

Is there a built-in way to get from a UIView to its UIViewController? I know you can get from UIViewController to its UIView

Answer 1

If your rootViewController is UINavigationViewController, which was set up in AppDelegate class, then

    + (UIViewController *) getNearestViewController:(Class) c {
NSArray *arrVc = [[[[UIApplication sharedApplication] keyWindow] rootViewController] childViewControllers];

for (UIViewController *v in arrVc)
{
    if ([v isKindOfClass:c])
    {
        return v;
    }
}

return nil;}

Where c required view controllers class.

USAGE:

     RequiredViewController* rvc = [Utilities getNearestViewController:[RequiredViewController class]];
