find ios Version

Finding the IOS version on a device programatically.

key here is to use the NSFoundationVersionNumber  and compare it with the in built NSFoundationVersionNumber_iOS_7_1  or what ever other ones you want to compare.

For my need i am just checking to see if the IOS version is atleast 8 and above..

-(bool) isOSAtleastVersion8{
     bool is_IOS8=false;
     if(floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_7_1)
     {
        is_IOS8=true;
     }
     else
     {
           is_IOS8=false;
     }

 return is_IOS8;
}
