iPhone App on iPad not responding to touch at first start

Question

If my iPhone App (not universal) starts in landscape mode on my iPad (3rd gen) it does not respond to any touch until I either press the 1x/2x Button or change the orientation. After that it works as normal. If I start it on my iPhone 5 in landscape mode, it works like a charm.

shouldAutorotateToInterfaceOrientation gives a YES in every View, so I think that's not the problem here.

The first View is a tabbar-view.

Answer 1

I have the same problem too on my iPad mini with iOS6.0.1.

What I do to solve the problem is to set the Supported interface orientations to all off in the info.plist.

Next, add the Supported interface orientations (iPad) in info.plist and only add the Potrait (bottom home button) in it.

It should make no difference to the apps orientation provided that you set it properly in the view controller. Also, make sure you set a correct initial interface orientation.

It then solves my problem.

The above answers are a bit difficult, especially when using Xamarin. This answer does work:

The comment of Daniel Sandland did solve it for me:

[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];
