//在iOS5.1 和 之前的版本中, 我们通常利用 shouldAutorotateToInterfaceOrientation: 来单独控制某个UIViewController的旋屏方向支持
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
return UIInterfaceOrientationIsLandscape(toInterfaceOrientation);
}
//但是在iOS6中,这个方法被废弃了,取而代之的是这俩个组合:
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeRight;
}
//如果整个应用所有view controller都不支持旋屏
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
return UIInterfaceOrientationMaskPortrait;
}
