當需求有a頁面支持橫屏和豎屏外，其他都是豎屏
我現在的做法是：
1）AppDelegate.m
- (BOOL)shouldAutorotate {
?? return NO;
}

- (NSUInteger)supportedInterfaceOrientations {
????
????return NO;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
????return??UIInterfaceOrientationPortrait;

}

2)A頁面
- (BOOL)shouldAutorotate {
????return YES;
}

- (NSUInteger)supportedInterfaceOrientations {
????
????return UIInterfaceOrientationMaskAll;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
????return??UIInterfaceOrientationPortrait;
}

?

// 注iOS9?

#if __IPHONE_OS_VERSION_MAX_ALLOWED < __IPHONE_9_0

- (NSUInteger)supportedInterfaceOrientations

#else

- (UIInterfaceOrientationMask)supportedInterfaceOrientations

#endif

{

? ? return?UIInterfaceOrientationMaskPortrait;

}
