CocoaLumberjack: XcodeColors doesn't work

I follow the step to configured the xcode but the content in output did’t render with color but with messy code.

    //Adds the logger to the console (similar to nslog)
    [DDLog addLogger:[DDTTYLogger sharedInstance]];
    // And we also enable colors
    [[DDTTYLogger sharedInstance] setColorsEnabled:YES];

    DDLogWarn(@"waring");
    DDLogError(@"error");

[38;5;130m2012-08-03 22:22:50:735[10875:c07] waring
2012-08-03 22:22:50:735[10875:c07] error


[38;5;130m and  are the messy code.

I also test with xcodecolor test project and it works fine.

Thanks.
