Automatic orientation support for iPhone and iPad apps
Q: What is needed to support multiple orientations in my iPhone and iPad apps?
A: There are two things you must implement to automatically support multiple orientations in your iPhone and iPad apps: provide launch images, and update your app's
Information Property List. To support multiple orientations on iOS 5 and below, your app's view controllers need to implement the
Provide Launch Images
iPhone-only applications may only include one launch image. This is because all applications on iPhone are launched in portrait to match the home screen orientation. If your iPhone app is designed to start in landscape, see Q&A: Launch Image Doesn't Show Up for iPhone Apps for information about preparing your launch images.
iPad-only applications should include launch images for each supported orientation.
Universal applications should include both iPhone and iPad specific launch images.
Refer to the App Launch Images section in the iOS App Programming Guide for launch image dimensions and names.
For information about designing launch images, refer to the Launch Images section in the iOS Human Interface Guidelines.
Update Your App's Information Property List
In your app's
Information Property List (
Info.plist), add values to the
Supported interface orientations (
UISupportedInterfaceOrientations) key for the supported orientations.
See the Information Property List Key Reference for possible values.
Implement the Proper Methods In Your App's View Controllers
To support multiple interface orientation on iOS 6 and later, your view controller classes do not need to implement any additional methods. Beginning with iOS 6, view controllers support all orientations on iPad and all orientations except portrait upside-down on iPhone by default.
If your app supports iOS 5 and below
In each of your
UIViewController classes, implement the
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation method to return YES for the supported
UIInterfaceOrientation constants. This method should return
YES to support all orientations.
See Q&A: Why won't my UIViewController rotate with the device? for possible reasons your view controller does not rotate.
