這是我的源文件的URL

-(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); 
    } 


    } 

我在哪裏錯了？

您可以將文件從源路徑複製到目標路徑。嘗試這樣

-(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); 
    } 


    }
