How to check which iOS version your device is running

We can check the UIDevice’s property systemVersion for this. Here’s a quick snippet that checks this, and conveniently checks the first number in the returned value. This should work until iOS 9…

NSArray *versionArray = [[[UIDevice currentDevice] systemVersion] componentsSeparatedByString:@"."];
    
if ([[versionArray objectAtIndex:0] intValue] >= 7) {
        
    // do this if we're runnign iOS 7 or higher
    return @"iOS 7 or higher";
        
} else {
        
    // do this if we're running iOS 6 or below     
    return @"iOS 6 or lower";
}

I’ve created a demo project for this code on GitHub:
