I want to put text into a CCLabelBMFont class which takes a char, however the iOS SDK is returning my value as a NSString. How can I put the NSString as text into the CCLabelBMFont? A search on google didn’t turn up with much help on converting a NSString to char

Specially refer “Getting C Strings” section. It offers many methods.
