如何启用iPod的控制的背景下，以控制非的iPod音乐在iOS 4的？ [英] How to enable iPod controls in the background to control non-iPod music in iOS 4?

问题描述

的什么，我试图完成在 Spotify的 iPhone应用程序的最新版本中实现一个很好的例子（潘多拉似乎具有相同的功能）。

A good example of what I'm trying to accomplish is implemented in the latest version of the Spotify iPhone application for (Pandora seems to have the same feature) .

在Spotify的是在后台，双点击打开多任务坞，其中iPod的控制（播放/暂停，前进等），让控制的Spotify的音乐播放（不是iPod的应用程序）。此外，当iPhone / iPod touch的已被锁定，双攻显示类似播放控件。

When Spotify is in the background, double tapping opens the "multi-task dock", where the ipod controls (play/pause, forward etc) allow to control the music playback of Spotify (not the ipod application). Also, when the iphone/ipod touch is locked, double tapping displays similar playback controls.

如果你不明白我的意思，这里有屏幕截图的文章：

If you don't know what I mean, here's an article that has screenshots : http://www.wired.com/gadgetlab/2010/07/spotify-updated-for-ios4-ready-to-replace-ipod/

在我当前的应用程序，音乐是从服务器（使用马特·加拉格尔的AudioStreamer）流。我已经成功地保持音乐在后台播放。现在，我想我的播放链接到多任务码头/锁屏。

In my current application, music is streamed from a server (using Matt Gallagher's AudioStreamer). I've managed to keep the music playing in the background. Now, I'd like to link my playback to the "multi-task dock"/lock screen.

我应该使用 [MPMusicPlayerController iPodMusicPlayer] ？我该如何操作？

Should I be using [MPMusicPlayerController iPodMusicPlayer] ? How should I proceed ?

奖金的问题：如果你能告诉我如何在iPod图标更改为我的应用程序图标中的多任务坞（Spotify的拉那招，以及...），这是对子级真棒

Bonus question : if you can tell me how to change the ipod icon to my application icon in the "multi-task dock" (Spotify pulled that trick as well...), that whould be AWESOME.

任何帮助AP preciated，谢谢。

Any help appreciated, thanks.

推荐答案

问题就解决了​​。

总之，要启用远​​程控制的事件，1）使用方法：

In short, to enable remote control event, 1) use :

- （无效）remoteControlReceivedWithEvent：（*的UIEvent）theEvent

和2）把这个就是你的视图控制器：

and 2) put this is your view controller :

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    [[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
    [self becomeFirstResponder];
}
- (BOOL)canBecomeFirstResponder {
    return YES;
}

我要给予信贷资助。他已经分叉的马特·加拉格尔的AudioStreamer使所有的iOS4改进（背景音乐，和工作遥控器）。你可以找到他的消息来源与在github工作样品一起： http://github.com/DigitalDJ/AudioStreamer

关于图标：一旦你使用了 beginReceivingRemoteControlEvents ，图标会自动切换到您的应用程序图标。辉煌！

Regarding the icon : once you use beginReceivingRemoteControlEvents, the icon automatically switches to your app icon. Brilliant !
