iPhone OS: Tap status bar to scroll to top doesn't work after remove/add back

Question

Using this method to hide the status bar:

[[UIApplication sharedApplication] setStatusBarHidden:YES animated:YES];

When setting \"hidden\"

Answer 1

I had a similar problem after playing a Youtube video within my app. scrollsToTop was still set to YES but tapping the status bar had no effect.

I finally realised that my app window was no longer the key window. After adding the following line to a UIWindow subclass (which I already had for other reasons) everything worked as it should again:

if (![self isKeyWindow]) [self makeKeyWindow];
