IOS设备方向卡在纵向模式下，没有横向

Question

I'm using Xcode 4.3.2 and an iPad simulator 5.1

I really need some help with this, my app is stuck at portrait mode.

When I rotate the simulator I've tried looking under the project settings and have these checked: Portrait, Upside Down, Landscape Left and Landscape Right.

I also these methods in the view controllers:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return YES;
}

can anyone please help?

Answer 1

Check your supporting orientations in the project's settings or on *.plist file. Also, if you are using UITabBarController or smth else, all of your controllers have to support all orientations!

Answer 2

use cmd+shift+f and type - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

make sure all of them return YES if you want all orientations supported and NO For unsupported orientations

Answer 3

Make sure you only have one controller showing. I've seen this problem when I have multiple views with different controllers showing at the same time.

Answer 4

Yeah I had the same problem and the other answers here didn't fix my situation. I found I had to check the "Resize View from NIB" box in all the relevant views .

See screenshot below (although shows a slightly older version of XCode).
