objective-c - 在xcode中播放音频

Question

我正在尝试播放设备上保存的音频，但已将其放置在路径中，但无法正常工作
任何人都可以帮忙吗？

NSURL *url = [NSURL fileURLWithPath:@"/Users/Luna/Library/ApplicationSupport/iPhone Simulator/5.0
/Applications/E3D65190-9DE0-4C60-A2F8-0948970A1788/Documents/Sound1.caf"];
    

NSError *error;

audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];

audioPlayer.numberOfLoops = -1;
    [audioPlayer play];

Answer 1

    NSFileManager* manager = [[NSFileManager alloc] init]; 

       NSString *documentsDirectory = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];

        NSLog(@"Documents directory: %@",[manager contentsOfDirectoryAtPath:documentsDirectory error:&error]);

    NSString* yourFile =[documentsDirectory() stringByAppendingPathComponent:@"Sound1.caf"];

    if ([manager fileExistsAtPath:yourFile]) {
    NSLog(@"Audio Exists");

   }

上面的代码将输出您的文档目录内容..并且最后还应记录音频存在 ...尝试此操作，让我们知道您将获得什么输出
