You can query the NSFoundationVersionNumber like so:
|
1 2 3 4 5 6 7 |
if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1) { // you're running iOS 6.1 or earlier } else { // you're running iOS 7 or later } |
Note that if you’re compiling with an older SDK, the value you’re querying may not be defined – in which case, you must define it manually at the beginning of your class:
|
1 2 3 |
#ifndef NSFoundationVersionNumber_iOS_6_1 #define NSFoundationVersionNumber_iOS_6_1 993.00 #endif |
