玩在iOS应用中的视频：音频，但没有图片 [英] Playing a video in iOS app: audio but no picture

问题描述

我想一个简短的视频在我的iphone应用程序播放。当我使用code以下时，我只能听到声音，看
该应用程序的常规视图。我希望视频这种观点之上玩。
我能做些什么呢？

 一个NSBundle *包=一个NSBundle mainBundle]
    * NSString的moviePath = [束pathForResource：@领头羊ofType：@MOV];
    NSURL * movieURL = [[NSURL fileURLWithPath：moviePath]保留];
    *的MPMoviePlayerController = theMovie [的MPMoviePlayerController页头] initWithContentURL：movieURL];
    theMovie.scalingMode = MPMovieScalingModeAspectFill;
    [theMovie播放];
    MPMoviePlayerViewController * moviePlayer = [[MPMoviePlayerViewController页头] initWithContentURL：movieURL];
    [自presentMoviePlayerViewControllerAnimated：moviePlayer];
 

解决方案

不要混淆的MPMoviePlayerController 和 MPMoviePlayerViewController 。当您使用的MPMoviePlayerController 使用它像这样（的通常用于iPad上的的嵌入式视频）

 的MPMoviePlayerController *玩家=
        [的MPMoviePlayerController页头] initWithContentURL：myURL];
[player.view SETFRAME：myView.bounds]; //玩家的框架必须父母的匹配
[MyView的addSubview：pl​​ayer.view];
// ...
[播放器播放];
 

当您使用 MPMoviePlayerViewController 然后present与 presentMoviePlayerViewControllerAnimated视频：（通常为全屏视频的）。

i want a short video to play in my iphone app. When i use the code below, i only hear the audio and see the regular view of the app. I want the video to play on top of this view. What can i do about this?

    NSBundle *bundle = [NSBundle mainBundle];
    NSString *moviePath = [bundle pathForResource:@"LEADER" ofType:@"mov"];
    NSURL  *movieURL = [[NSURL fileURLWithPath:moviePath] retain];
    MPMoviePlayerController *theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
    theMovie.scalingMode = MPMovieScalingModeAspectFill;
    [theMovie play];
    MPMoviePlayerViewController *moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL];
    [self presentMoviePlayerViewControllerAnimated:moviePlayer];

解决方案

Don't mix up MPMoviePlayerController and MPMoviePlayerViewController. When you use MPMoviePlayerController use it like this (typically for embedded videos on the iPad):

MPMoviePlayerController *player =
        [[MPMoviePlayerController alloc] initWithContentURL: myURL];
[player.view setFrame: myView.bounds];  // player's frame must match parent's
[myView addSubview: player.view];
// ...
[player play];

When you use MPMoviePlayerViewController then present the video with presentMoviePlayerViewControllerAnimated: (typically for fullscreen videos).
