New iAd crashes in iOS 6

Question

With iOS 7 Apple introduced a new iAd function:

self.canDisplayBannerAds = YES;

In iOS 7 this works great. But if i run my App on an iOS 6 device, the App crashes.

In this way it works:

    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7)
   {
    self.canDisplayBannerAds = YES;
   }

My question: is this the normal way, or is there a better solution?

The better solution is to check if the method is available:

if ([self respondsToSelector:@selector(setCanDisplayBannerAds:)]) {
    self.canDisplayBannerAds = YES;
}

Thanks! How does this work with this: [UIViewController prepareInterstitialAds]; – Jonas Ester Oct 23 '13 at 19:56
