Editor to share with you how to achieve iOS horizontal and vertical screen settings, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Horizontal and vertical screen below iOS 6, rewrite the method in ViewController

-(BOOL) shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation) toInterfaceOrientation {/ / system macro definition only horizontal screen return UIDeviceOrientationIsLandscape (toInterfaceOrientation); / / system macro definition only vertical screen return UIDeviceOrientationIsPortrait (toInterfaceOrientation); / / you can also implement vertical screen only, with the home key below return (toInterfaceOrientation = = UIDeviceOrientationPortrait); / / you can also implement vertical screen only with home key return above (toInterfaceOrientation = = UIDeviceOrientationPortraitUpsideDown) / / you can also implement vertical screen only on your own, with return button on the right (toInterfaceOrientation = = UIDeviceOrientationLandscapeLeft); / / you can also implement vertical screen only on your own, and home button is return on the left (toInterfaceOrientation = = UIDeviceOrientationLandscapeRight);}

IOS 6 or above, set in AppDelegate. After setting, you need to set the screen in Target "Summary" Support Interface Orientations. Failure to set the same screen will cause flicker.
