registerForRemoteNotificationTypes: is not supported in iOS 8.0 and later.

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
{
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings
     settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge)
categories:nil]];

    [[UIApplication sharedApplication] registerForRemoteNotifications];
}
else
{
//这里还是原来的代码
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
     (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
}

判断PUSH是否打开

{
UIRemoteNotificationType types;
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
   {
 types = [[UIApplication sharedApplication] currentUserNotificationSettings].types;
    }
else
   {
 types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
    }

return (types & UIRemoteNotificationTypeAlert);
}
