    To redirect the log statements to a file instead of console call the following function at the start of function applicationDidFinishLaunching.

    - (void)redirectConsoleLogToDocumentFolder
    {
        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                                             NSUserDomainMask, YES);
        NSString *documentsDirectory = [paths objectAtIndex:0];
        NSString *logPath = [documentsDirectory stringByAppendingPathComponent: @"filename.log"];
        freopen([logPath fileSystemRepresentation],"a+",stderr);
    }
