iPhone MPMoviePlayerController上的下一个/上一个按钮 [英] Next/Previous buttons on iPhone MPMoviePlayerController

问题描述

使用MPMoviePlayerController时，播放按钮被下一步和上一页按钮包围。

When using the MPMoviePlayerController, the play button is surrounded with "Next" and "Previous" buttons.

如何点击通知？
有没有办法用内容列表（数组）提供MPMoviePlayerController？

How do I get notifications when they are clicked? is there a way to feed MPMoviePlayerController with a list (array) of content?

推荐答案

Nathan对于需要是正确的如果您想要按钮通知，请为播放器实现自己的UI。您可以从播放器获取有关播放状态的通知。

Nathan is correct about needing to implement your own UI for the player if you want button notifications. You can get notifications from the player about playback state though.

来自AddMusic示例，其中self是包含MPMusicPlayerController实例的控制器或模型：

from the AddMusic example, where self is the controller or model containing the instance of MPMusicPlayerController:

- (void) registerForMediaPlayerNotifications {

    NSNotificationCenter *notificationCenter = [NSNotificationCenter defaultCenter];

    [notificationCenter addObserver: self
                           selector: @selector (handle_NowPlayingItemChanged:)
                               name: MPMusicPlayerControllerNowPlayingItemDidChangeNotification
                             object: musicPlayer];

    [notificationCenter addObserver: self
                           selector: @selector (handle_PlaybackStateChanged:)
                               name: MPMusicPlayerControllerPlaybackStateDidChangeNotification
                             object: musicPlayer];

    /*
     // This sample doesn't use libray change notifications; this code is here to show how
     //     it's done if you need it.
     [notificationCenter addObserver: self
     selector: @selector (handle_iPodLibraryChanged:)
     name: MPMediaLibraryDidChangeNotification
     object: musicPlayer];

     [[MPMediaLibrary defaultMediaLibrary] beginGeneratingLibraryChangeNotifications];
     */

    [musicPlayer beginGeneratingPlaybackNotifications];
}
