Question

我正在创建一个应用程序，我可以在其中播放我通过mpmovieplayer控制器执行的视频。现在我需要为两个方向执行此操作。但框架没有正确设置。

代码如下

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    [super viewDidLoad];
    [self shouldAutorotateToInterfaceOrientation:[UIDevice currentDevice].orientation];

    NSURL *temp = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"Floating" ofType:@"mp4"]];
    mpviewController = [[MPMoviePlayerViewController alloc] initWithContentURL:temp]; 
    mpviewController.view.frame = CGRectMake(0, 0, 768, 1024);
    mpviewController.view.backgroundColor = [UIColor clearColor]; 
    mpviewController.moviePlayer.movieSourceType = MPMovieSourceTypeFile; 
    mpviewController.view.userInteractionEnabled= NO;
    mpviewController.moviePlayer.fullscreen= YES;
    mpviewController.moviePlayer.controlStyle = MPMovieControlStyleNone;
    [[mpviewController moviePlayer] play];

    [self.view addSubview:mpviewController.view]; 

}
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    currentOrientation = interfaceOrientation;
    //[self SetInterface];

    if(interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)
        mpviewController.view.frame = CGRectMake(0, 0, 768, 1024);
    else if(interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight)
        mpviewController.view.frame = CGRectMake(0, 0, 1024, 768);




    return YES;
}

我不知道我错在哪里。请让我知道代码中的任何问题。为了获得正确的方向。

你应该只在shouldAutorotateToInterfaceOrientation:方法中返回YES或NO，它仅由框架调用以获取有关控制器中支持的方向的信息，请阅读Apple文档。

您需要注册方向更改通知

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationChanged:) name:@"UIDeviceOrientationDidChangeNotification" object:nil];

实施orientationChanged:方法。

//********** ORIENTATION CHANGED **********
- (void) orientationChanged:(NSNotification *)note
{
    NSLog(@"Orientation  has changed: %d", [[note object] orientation]);
   //Put your code here from shouldAutorotateToInterfaceOrientation:
}

不要忘记删除。

[[NSNotificationCenter defaultCenter] removeObserver:self];

<强>第一我相信你不需要调整mpviewController的大小，因为它会单独调整它的大小。你应该只设置 -

<强>第二

在shouldAutorotateToInterfaceOrientation中，您只在shouldAutorotateToInterfaceOrientation中设置支持的方向。

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {  
        return YES;
}

如果不这样做，您可以在 -

中更改视图属性

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration{

    if (UIInterfaceOrientationIsPortrait(interfaceOrientation)){
     //do what you want for portrait
     }else{
     //do what you want for landscape
    }

}

无需更改任何编码。简单地将以下编码插入应用程序，它将自动检测方向...

UINavigationBar * bar = [self.navigationController navigationBar];
[bar setTintColor：[UIColor blackColor]]; NSBundle * bundle = [NSBundle mainBundle];
NSString * moviePath = [bundle pathForResource：@“sharkdivertrailer”ofType：@“mp4”];
NSURL * movieURL = [[NSURL fileURLWithPath：moviePath] retain];
        MPMoviePlayerController * theMovie = [[MPMoviePlayerController alloc] initWithContentURL：movieURL];

        theMovie.view.frame = CGRectMake（184,200,400,300）;         [电影剧];
        MPMoviePlayerViewController * moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL：movieURL];
        [self presentMoviePlayerViewControllerAnimated：moviePlayer];
