UIAlertController if iOS 8, otherwise UIAlertView

Question

I want to conform to the UIAlertController used in iOS 8 since UIAlertView is now deprecated. Is there a way that I can use this without breaking support for iOS 7? Is there

Answer 1

// Above ios 8.0
float os_version = [[[UIDevice currentDevice] systemVersion] floatValue];
if (os_version >= 8.000000)
{
   　　　//Use UIAlertController    
}
else
{
     //UIAlertView
}
