iphone - 我无法使用 AVAudioPlayer 播放 mp3 文件

Question

我想播放放置在资源中的mp3文件，代码如下，

NSString *st=@"alarm_1.mp3";
NSLog(st);
NSURL* musicFile = [NSURL fileURLWithPath:st]; 

AVAudioPlayer *click = [[AVAudioPlayer alloc] initWithContentsOfURL:musicFile error:nil];

//AVAudioPlayer *click1=[[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL URLWithString:@"alarm_1.mp3"]];

[click prepareToPlay];
[click play];
[click release];

但不幸的是我听不到声音请帮忙

我认为您的文件名不正确。试试这个语法:

    NSURL *clickURL = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/alarm_1.mp3", [[NSBundle mainBundle] resourcePath]]];  
    AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:clickURL error:nil];
