How can you determine and compare (>, <, etc.) the current OS version of the iPhone that the app is running on? There is a certain bug in 3.0 but not in 3.1+ so I’d like to be able to skip out a bit of code if the current OS version is not >= 3.1.
This needs to be at runtime not compile time!
Do you mean determine the version of the OS? The SDK is fixed at build time, but the OS may change. To get the OS version, use [UIDevice currentDevice]. systemVersion. To get the SDK version, I think you can use __IPHONE_OS_VERSION_MIN_REQUIRED.
