iOS 如何让某个页面单独横屏

直接附上代码

#if __IPHONE_OS_VERSION_MAX_ALLOWED < __IPHONE_9_0

- (NSUInteger)supportedInterfaceOrientations

#else

- (UIInterfaceOrientationMask)supportedInterfaceOrientations

#endif

{

    returnUIInterfaceOrientationMaskLandscape;

}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {

    

    returnUIInterfaceOrientationLandscapeRight;

}

直接将代码附在页面的viewcontroller里，强制横屏
