MPNowPlayingInfoCenter
这里是一个可以在iOS 5上运行的示例代码,它不会在旧版本的iOS上崩溃.
Class playingInfoCenter = NSClassFromString(@"MPNowPlayingInfoCenter");
if (playingInfoCenter) {
MPNowPlayingInfoCenter *center = [MPNowPlayingInfoCenter defaultCenter];
NSDictionary *songInfo = [NSDictionary dictionaryWithObjectsAndKeys:
@"Some artist",MPMediaItemPropertyArtist,@"Some title",MPMediaItemPropertyTitle,@"Some Album",MPMediaItemPropertyAlbumTitle,nil];
center.nowPlayingInfo = songInfo;
}
