代码如下：

    //register for push notification
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8)
    {
        [[UIApplication sharedApplication] registerForRemoteNotifications];
        
        UIUserNotificationType types = UIUserNotificationTypeBadge                                                                                                                      | UIUserNotificationTypeSound | UIUserNotificationTypeAlert ;
        
        UIUserNotificationSettings * setting =  [UIUserNotificationSettings settingsForTypes:types categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:setting];
        
        
        NSLog(@"isIOS8");
    }
    else
    {
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes: (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
        
        NSLog(@"not isIOS8");
    }
    
    
    
    BOOL  bPushEnable = NO;
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8)
    {
        UIUserNotificationSettings * pushSetting =  [[UIApplication sharedApplication] currentUserNotificationSettings];
        if (pushSetting)
        {
            UIUserNotificationType   pushType =  pushSetting.types;
            NSLog(@"push type = %d", pushType);
            if (pushType == UIUserNotificationTypeNone)
            {
                bPushEnable = NO;
            }
            else
            {
                bPushEnable = YES;
            }
        }
    }
    else
    {
        UIRemoteNotificationType pushType = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
        
        NSLog(@"push type = %d", pushType);
        if (pushType == UIRemoteNotificationTypeNone)
        {
            bPushEnable = NO;
        }
        else
        {
            bPushEnable = YES;
        }
    }
    
    //如果不能推送
    if (bPushEnable == NO)
    {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:[UtilsHelper getLocalizeString:@"text_push_notification_title"] message:[UtilsHelper getLocalizeString:@"text_push_notification_content"] delegate:self cancelButtonTitle:[UtilsHelper getLocalizeString:@"text_yes"] otherButtonTitles:nil, nil];
        [alert show];
    }
