SETUP從一個NSBundle
播放MP3我把MP3變成我的包只是爲了測試,我將它們下載到的文件目錄。但現在我要解決這個問題。
我找到了一對夫婦的教程,但沒有任何我需要的東西。下面絕對是一對夫婦的解決方案的組合,可能不是最好的方法。
問題
如何我拉一首我的包和應用程序內玩?
//Create an instance of MPMusicPlayerController
MPMusicPlayerController* myPlayer = [MPMusicPlayerController applicationMusicPlayer];
//Read the song off the bundle.
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"LittleMoments" ofType:@"mp3"];
NSData *myData = [NSData dataWithContentsOfFile:filePath];
if (myData) {
//This wont work for me because i don't want to query songs from the iPod,
i want to play songs out of the Bundle.
//Create a query that will return all songs by The Beatles grouped by album
MPMediaQuery* query = [MPMediaQuery songsQuery];
[query addFilterPredicate:[MPMediaPropertyPredicate predicateWithValue:@"The Beatles" forProperty:MPMediaItemPropertyArtist comparisonType:MPMediaPredicateComparisonEqualTo]];
[query setGroupingType:MPMediaGroupingAlbum];
//Pass the query to the player
[myPlayer setQueueWithQuery:query];
/////**** how can i get nsdata into MyPlayer?*****//////
//Start playing and set a label text to the name and image to the cover art of the song that is playing
[myPlayer play];
}
我得到這樣的警告:通過視圖 - 控制* const_strong到incompatiable ID類型的參數。它還在[audioPlayer播放]上提供了BAD_EXEC; –

刪除audioPlayer.delegate = self;或者將AVAudioPlayerDelegate作爲協議添加到ViewController中。 – tim 2012-03-08 22:24:16
感謝您的幫助。我只是google了AVAudioPlayer,發現這個教程和它的奇蹟。 http://mobileorchard.com/easy-audio-playback-with-avaudioplayer/再次感謝 – zach 2012-03-10 06:08:37
