評論這個文檔，它會幫助你。

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];
