如何捕获MPMoviePlayerController旋转事件？

Question

我在ViewController中添加了这段代码。

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{
if (interfaceOrientation != UIInterfaceOrientationPortrait) {
    [self.moviePlayerController setFullscreen:YES animated:YES]; 
} 
return YES;
}

所以旋转后我的播放器以全屏模式播放视频。我需要在playerController（OrientationPortrait）中捕获旋转事件to setFullScreen：NO。 我怎样才能做到这一点？ 谢谢你的回答。

不应在此功能中处理moviePlayerController的方向设置。

在viewWillAppear函数中添加通知程序

-(void)viewWillAppear:(BOOL)animated{
[[NSNotificationCenter defaultCenter] addObserver:self  selector:@selector(orientationChanged:)  name:UIDeviceOrientationDidChangeNotification  object:nil];}

方向更改通知此功能

- (void)orientationChanged:(NSNotification *)notification{
[self adjustViewsForOrientation:[[UIApplication sharedApplication] statusBarOrientation]];}

---

进而调用此函数处理moviePlayerController框架的方向

- (void) adjustViewsForOrientation:(UIInterfaceOrientation) orientation {

if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown) 
{ 
    [self.moviePlayerController setFullscreen:NO animated:YES];    
}
else if (orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight) 
{
    [self.moviePlayerController setFullscreen:YES animated:YES]; 
}}

在viewDidDisappear中删除通知

-(void)viewDidDisappear:(BOOL)animated{
[[NSNotificationCenter defaultCenter]removeObserver:self name:UIDeviceOrientationDidChangeNotification object:nil];}
