查看此文档，它会对您有所帮助。

NSString *docPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,    NSUserDomainMask, YES)objectAtIndex:0];
NSString *filePath = [docPath stringByAppendingPathComponent:@"sound.aac"];//Audio file

NSURL *fileUrl     = [NSURL fileURLWithPath:filePath isDirectory:NO];
NSArray *activityItems = @[fileUrl];

UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
[self presentViewController:activityVC animated:YES completion:nil];

Answer 2

在小赌注之后，上面的答案对我有用。我认为访问文件路径存在一些问题。这是经过修改和测试的代码。

   NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:@"sampleFile"  ofType:@"mp3"];
   NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];
   NSArray *activityItems = @[soundFileURL];

   UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
   [self presentViewController:activityVC animated:YES completion:nil];
