ios - 单击按钮时未播放音频

Question

我想在Button单击上播放音频。我已经尝试过此代码，但是音频无法播放:-

NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:@"sound" ofType:@"mp3"];
NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];
AVAudioPlayer *audioPlayer  = [[AVAudioPlayer alloc] initWithData:soundFileURL error:nil];
audioPlayer.delegate = self;
audioPlayer.volume=1.0;
[audioPlayer setNumberOfLoops:1];
[audioPlayer play];

Answer 1

您尚未创建播放器项目

//在.h文件中声明

AVPlayerItem *playerItem;

//然后在.m文件中

player = [AVPlayer playerWithPlayerItem:playerItem];

之后播放

   [player play];
