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,比如:
复制代码- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
但是在iOS6中,这个方法被废弃了,使用无效。
shouldAutorotateToInterfaceOrientation:
Returns a Boolean value indicating whether the view controller supports the specified orientation. (Deprecated in iOS 6.0. Override the supportedInterfaceOrientations andpreferredInterfaceOrientationForPresentation methods instead.)
实践后会发现,通过supportedInterfaceOrientations的单独控制是无法锁定屏幕的。
复制代码-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
多次实验后总结出控制屏幕旋转支持方向的方法如下:
子类化UINavigationController,增加方法
- (BOOL)shouldAutorotate
{
return self.topViewController.shouldAutorotate;
}
- (NSUInteger)supportedInterfaceOrientations
{
return self.topViewController.supportedInterfaceOrientations;
}
并且设定其为程序入口,或指定为 self.window.rootViewController
随后添加自己的view controller,如果想禁止某个view controller的旋屏:(支持全部版本的控制)
复制代码
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
-(BOOL)shouldAutorotate
{
return NO;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
