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

Much simpler:

#define IS_IOS6_AND_UP ([[UIDevice currentDevice].systemVersion floatValue] >= 6.0)
