Detect iOS version in runtime

Question

I'm currently writing an app that uses Facebook integration built into iOS 6. Now in order to do that, I need to

#import <Social/Social.h>

How do I ensure that the device can actually run the code and won't crash (check if it's iOS 6 or iOS 5.1 and then performing the right code, because I support iOS 5.1<= )?

You could use:

[[UIDevice currentDevice] systemVersion]

@harrym17 Use that for the actually implementation, then in your project summary tab change the social framework from required to optional. – Mick MacCallum Oct 03 '12 at 17:59

This works fine for me:

if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"6.0")){
//Use social framework
}else{
//other option
}

Won't work unless you define it somewhere: http://stackoverflow.com/questions/7848766/how-can-we-programmatically-detect-which-ios-version-is-device-running-on – Ngoan Nguyen Feb 06 '13 at 21:25
