CCLabelTTF not visible (works fine on Android).

Hi,
I’m having trouble displaying CCLableTTF in my game. I’v written and deployed the code in android and it works just fine. But on mac, none of the CCLableTTFs are visible(simulator and device). I don’t get any warning or error when i run the code. Just to make sure there was nothing wrong with my code, I created a new cocos2dx project and ran the helloworld. Even in that, the “Hello World” lable is not visible. I’ve tried setting breakpoints to check if the lable is being initialized properly, but nothing wrong there as well. I’m using

cocos2dx 2.1.4
iOS version 10.6.8 Snow Leopard
xcode v4.2 with ios sdk 5.0

Any help?

Have you tried running the sample code?
Try setting a different font on cclabelTTF.

Yes. Cannot see any text in that either. Tried changing the font too.
