Question

真的希望有人可以提供帮助，我可以通过点击按钮让我的视频播放，但他们总是以纵向模式播放，我真的希望他们以全屏风格播放。

以下是我在这里使用的代码，我在这里添加了一些代码，有人说在他们的情况下修复了它，但无疑有些方法搞砸了语法。

请有人把我从痛苦中解脱出来告诉我，我做错了什么显而易见的事。

#import "SecondViewController.h"


@implementation SecondViewController


// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad
{
[super viewDidLoad];
self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"BG.png"]];
}

// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:  (UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
//return (interfaceOrientation == UIInterfaceOrientationPortrait);
return YES;
}

-(IBAction)playMovie:(id)sender
{
NSString *filepath   =   [[NSBundle mainBundle] pathForResource:@"Allerjen Exclusive" ofType:@"mp4"];
NSURL    *fileURL    =   [NSURL fileURLWithPath:filepath];
MPMoviePlayerController *moviePlayerController = [[MPMoviePlayerController alloc]   initWithContentURL:fileURL];

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlaybackComplete:)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:moviePlayerController];

[self.view addSubview:moviePlayerController.view];
moviePlayerController.fullscreen = YES;

UIView * playerView = [moviePlayerController view];
[playerView setFrame: CGRectMake(0, 0, 480, 320)];

CGAffineTransform landscapeTransform;
landscapeTransform = CGAffineTransformMakeRotation(90*M_PI/180.0f);
landscapeTransform = CGAffineTransformTranslate(landscapeTransform, 80, 80);

[playerView setTransform: landscapeTransform];

moviePlayerController.fullscreen = TRUE;
moviePlayerController.controlStyle = MPMovieControlStyleFullscreen;

[moviePlayerController play];


}

- (void)moviePlaybackComplete:(NSNotification *)notification
{
MPMoviePlayerController *moviePlayerController = [notification object];
[[NSNotificationCenter defaultCenter] removeObserver:self
                                                    name:MPMoviePlayerPlaybackDidFinishNotification
                                              object:moviePlayerController];

[moviePlayerController.view removeFromSuperview];
[moviePlayerController release];
}


@end

Answer 1

我认为你需要在方向改变时改变moviePlayer视图的框架，使用以下功能：

 - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
/* Size movie view to fit parent view. */
CGRect viewInsetRect = CGRectInset ([self.view bounds],20,20);
[[[self moviePlayerController] view] setFrame:viewInsetRect];

}

Answer 2

使用MPMoviePlayerViewController而不是MPMoviePlayerController。它将处理方向，控制风格等。我提到https://stackoverflow.com/a/4911172/3346048也是如此。

MPMoviePlayerViewController *playerView = [[[MPMoviePlayerViewController alloc] initWithContentURL:videoURL] autorelease];
[self presentMoviePlayerViewControllerAnimated:playerView];

并在AppDelegate.m中声明以下函数。这将在所有情况下将方向限制为纵向，并且仅在播放视频时更改

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window

{ if（[[self.window.rootViewController presentsViewController] isKindOfClass：[MPMoviePlayerViewController class]]） { 返回UIInterfaceOrientationMaskAll; } 其他 { // NSLog（@＆＃34;方向应该改变＆＃34;）; 返回UIInterfaceOrientationMaskPortrait; }

}

MediaPlayer MPMoviePlayerController - 不在Landscape中播放视频
