Warning about supportedInterfaceOrientations

Your iOS project might get warning supportedInterfaceOrientations on Xcode 7.0. The cause is just building for iOS 9.

Conflicting return type in implementation of 'supportedInterfaceOrientations': 'UIInterfaceOrientationMask' (aka 'enum UIInterfaceOrientationMask') vs 'NSUInteger' (aka 'unsigned long')

What should I do?

Change return type for after iOS 9

- (NSUInteger)supportedInterfaceOrientations
　　　　↓
- (UIInterfaceOrientationMask)supportedInterfaceOrientations

This is useful coding if the project contain under iOS 9

#if __IPHONE_OS_VERSION_MAX_ALLOWED < 90000
- (NSUInteger)supportedInterfaceOrientations
#else
- (UIInterfaceOrientationMask)supportedInterfaceOrientations
#endif
{
   return UIInterfaceOrientationMaskPortrait;
}
