[iOS 8] iOS registerForRemoteNotificationTypes: is not supported in iOS 8.0 and later

Its very simple try this (Xcode6 Beta only):

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    //-- Set Notification
        if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
        {
            [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
            [[UIApplication sharedApplication] registerForRemoteNotifications];
        }
        else
        {
            [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
             (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
        }
     //--- your custom code
     return YES;
}
