How to continue to support iOS 5.1 as functions became deprecated

Vote count:

I have an app that must work for iOS versions >= 5.1.

Apple docs say that "The AudioSession API has been completely deprecated in iOS 7.0". And one should use AVAudioSession class instead.

But the method that I need (- (BOOL)setCategory:(NSString *)category withOptions:(AVAudioSessionCategoryOptions)options error:(NSError **)outError) is only available starting from iOS 6.0.

So it seems that I have to continue usage of deprecated AudioSessionSetProperty to support iOS 5.1.

What is a correct way to handle such situations (my question is general, not only about this particular problem with audio)? Should I write something like

if ([[[UIDevice currentDevice] systemVersion] compare:@"6.0" options:NSNumericSearch] == NSOrderedAscending)
{
    // use deprecated methods (AudioSessionSetProperty)
}
else
{
    // use brand-new methods (AVAudioSession)
}

or maybe it's ok to just use AudioSessionSetProperty until it stops to compile?
