Question

I am getting a file error when i am trying to write a string into a file:

 NSFileManager *filemgr;

    filemgr = [NSFileManager defaultManager];
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *docDir = [paths objectAtIndex: 0];
    NSString *docFile = [docDir stringByAppendingPathComponent:fileName];
  if ([file fileExistsAtPath: docFile] == YES)
    {    if(![formatedlogStr writeToFile:LOG_FILE_V1  atomically:YES encoding:NSUTF8StringEncoding error:&error])
            {
                NSLog(@"Error: %@", [error userInfo]);
            }

        }

this gives me an error :

Error: {
    NSFilePath = "error_log_V1.txt";
    NSUnderlyingError = "Error Domain=NSPOSIXErrorDomain Code=13 \"The operation couldn\U2019t be completed. Permission denied\"";
    NSUserStringVariant = Folder;

How to solve the problem I don’t know.
Can anybody help me?

You’re correctly finding a path within your documents directory, but you are trying to log the information to a bare path. You should follow the same procedure to build a path to a file within your sandbox for the log file and use that instead of LOG_FILE_V1.
