How to define preprocessor macro to check iOS version

Question

I use it to check iOS version, but it doesn\'t work:

#ifndef kCFCoreFoundationVersionNumber_iPhoneOS_5_0
#define kCFCoreFoundationVersionNumber_iPhoneOS_5_0          


        

Answer 1

You've defined a macro, but you're using it in the non-macro way. Try something like this, with your same macro definition.

IF_IOS5_OR_GREATER(NSLog(@"iOS5");)

(This is instead of your #if/#endif block.)
