这是我的目标网址

Dest url = /Users/vinodjadhav/Library/Developer/CoreSimulator/Devices/067A2EAC-9987-4861-8746-97117DCE72F2/data/Containers/Data/Application/5744F8BC-4256-4010-8A14-60B228859F88/Documents/XpenseTag/Xpenses/sagar/823564440/audio/audio.m4a

这是我的源文件网址

source url = file：/// Users / vinodjadhav / Library / Developer / CoreSimulator / Devices / 067A2EAC-9987-4861-8746-97117DCE72F2 / data / Containers / Data / Application / 5744F8BC-4256-4010-8A14-60B228859F88 /tmp/14-11-201410:32:45.m4a

 -(void)moveAudioFileFromeSource:(NSString *)sourceUrl toDest:(NSString *)destUrl
  {
    NSLog(@"source url = %@", sourceUrl);
    NSError *Error;
    if (![[NSFileManager defaultManager] moveItemAtPath:sourceUrl toPath:destUrl   
         error:&Error])
    {
        NSLog(@"Could not remove old files. Error:%@",Error);
    }


  }

我哪里错了？

您可以将文件从源路径复制到目标路径。试试这个

 -(void)moveAudioFileFromeSource:(NSString *)sourceUrl toDest:(NSString *)destUrl
  {
    NSLog(@"source url = %@", sourceUrl);
    NSError *Error;
    if (![[NSFileManager defaultManager] copyItemAtPath:sourceUrl toPath:destUrl   
         error:&Error])
    {
        NSLog(@"Could not remove old files. Error:%@",Error);
    }


  }

录制的音频文件不会移动？
