图像方向在启动时变形为错误的方向（iOS）

Question

I have an app, haven't modified it since 6 months ago, anyway I decided to open it up in the simulator. But the first viewcontroller which shows after the splash screen is scrunched up and is showing through the wrong orientation. It's showing in portrait when it should be showing in landscape.

This is the code for it:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

However,

When I tap to go to another view, then go back to the main viewcontroller, the problem fixes itself and the orientation is correct.

So it only happens on the initial launch after the splash screen is shown.

Please join the links together to view the screenshots as i cannot post images as i haven't got 10 reps yet.

Answer 1

This will make sure the app to open in landscape mode .

In the AppDelegate you may be using this

[self.window addSubView:viewControllerObj]

The problem was with the above line. Orientation will work properly with the above line in iOS 5 but in iOS 6, for orientation to work properly, change the above line with

[self.window setRootViewController:viewControllerObj]

Then the app rotates when orientation changes

Answer 2

Open your plist file ->addRow-> add "Initial interface orientation" and give value Landscape (left home button).

Hope this will help you.
