我没有收到任何通知MPMoviePlayerController.我究竟做错了什么？
我使用以下逻辑.
我开始播放youtube视频了UIWebView.UIWebView称之为标准MPMoviePlayerController.我不控制MPMoviePlayerController因为我没有实例化MPMoviePlayerController.
我使用自动播放运行youtube的剪辑(延迟1秒):
[self performSelector:@selector(touchInView:) withObject:b afterDelay:1];
我的代码是:
- (void)viewDidLoad
{
[super viewDidLoad];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(loadStateDidChange:) name:MPMoviePlayerLoadStateDidChangeNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playbackDidFinish:) name:MPMoviePlayerDidExitFullscreenNotification object:nil];
[self embedYouTube];
}
- (void)loadStateDidChange:(NSNotification*)notification
{
NSLog(@"________loadStateDidChange");
}
- (void)playbackDidFinish:(NSNotification*)notification
{
NSLog(@"________DidExitFullscreenNotification");
}
- (void)embedYouTube
{
CGRect frame = CGRectMake(25, 89, 161, 121);
NSString *urlString = [NSString stringWithString:@"http://www.youtube.com/watch?v=sh29Pm1Rrc0"];
NSString *embedHTML = @"<html><head>\
<body style=\"margin:0\">\
<embed id=\"yt\" src=\"%@\" type=\"application/x-shockwave-flash\" \
width=\"%0.0f\" height=\"%0.0f\"></embed>\
</body></html>"; …youtube mpmovieplayercontroller mpmovieplayer nsnotificationcenter ios
我的iPhone应用程序是一个纵向导向的应用程序,在我的应用程序中,我有UITableView一个UIWebView在第一个UITableCell.该UIWebView节目嵌入YouTube视频.当我点击视频播放时,它进入全屏模式.我需要做的是,允许用户旋转他们的设备并以横向模式播放视频.然后,当视频停止时,只允许再次使用肖像.我设置为在视频进入全屏并且全屏显示时收听通知.但我不知道如何以编程方式允许用户旋转界面方向.
所以我通常在传递通知时调用了2个方法
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(youTubeStarted:) name:@"UIMoviePlayerControllerDidEnterFullscreenNotification" object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(youTubeFinished:) name:@"UIMoviePlayerControllerDidExitFullscreenNotification" object:nil];
-(void)youTubeStarted:(NSNotification *)notification{
// Entered fullscreen code goes here.
}
-(void)youTubeFinished:(NSNotification *)notification{
// Left fullscreen code goes here.
}
我会在这两种方法中放置什么来仅在视频播放期间改变方向？
平台:iOS 6.1.Xcode 4.6.
我正在使用YouTube Javascript API和UIWebView.我可以手动点击视频缩略图,开始播放就好了.但是,自动播放不起作用.我正在为许多人建议的Web视图设置mediaPlaybackRequiresUserAction = NO.没运气.
这是代码:
@interface VideoPlayerController : UIViewController <UIWebViewDelegate>
@property(strong, nonatomic) IBOutlet UIWebView* webView;
@end
- (void) viewDidLoad
{
[super viewDidLoad];
self.webView.delegate = self;
NSString *template = [NSString stringWithContentsOfFile:
[[NSBundle mainBundle]
pathForResource:@"YouTubeTemplate" ofType:@"txt"]];
NSString *htmlStr = [NSString stringWithFormat: template,
200, 200,
@"3G4exdlsRkY"];
self.webView.mediaPlaybackRequiresUserAction = NO;
[self.webView loadHTMLString:htmlStr baseURL:nil];
}
- (void) webViewDidFinishLoad:(UIWebView *)wv {
self.webView.mediaPlaybackRequiresUserAction = NO;
}
YouTubeTemplate.txt文件是:
<html>
<head>
<script src="https://www.youtube.com/player_api"></script>
<style>
body, div {
margin: 0px;
padding: 0px;
}
</style>
</head>
<body> …
