【问题描述】：

更新：请注意我使用的是 Xcode 6.01 并使用此代码进行部署，但它不起作用，但是当我安装 Xcode 6.1 版本并部署它工作的代码时...所以它可能是 Xcode 版本问题会帮助别人。

我正在使用以下代码使用 PARSE.com 进行推送通知，它在 ios8 以下的所有设备中都可以正常工作，

if (application.applicationState != UIApplicationStateBackground) 
        // Track an app open here if we launch with a push, unless
        // "content_available" was used to trigger a background push (introduced in iOS 7).
        // In that case, we skip tracking here to avoid double counting the app-open.
        BOOL preBackgroundPush = ![application respondsToSelector:@selector(backgroundRefreshStatus)];
        BOOL oldPushHandlerOnly = ![self respondsToSelector:@selector(application:didReceiveRemoteNotification:fetchCompletionHandler:)];
        BOOL noPushPayload = ![launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
        if (preBackgroundPush || oldPushHandlerOnly || noPushPayload) 
            [PFAnalytics trackAppOpenedWithLaunchOptions:launchOptions];
        
    
    

我也用这些条件进行测试（在低于 ios 8 的情况下工作正常

如果 __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) 
    UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
                                                    UIUserNotificationTypeBadge |
                                                    UIUserNotificationTypeSound);
    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes
                                                                             categories:nil];
    [application registerUserNotificationSettings:settings];
    [application registerForRemoteNotifications];
 else

endif

    [application registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge |
                                                     UIRemoteNotificationTypeAlert |
                                                     UIRemoteNotificationTypeSound)];

即使iOS 8 enabled device not receiving PUSH notifications after code update 不适合我 我正确设置了通知，我的捆绑标识符设置也正确

【问题讨论】：

你得到设备令牌了吗？

是的，即使在 parse.com 中，我也知道推送正在传递，但在我的设备（iPhone/ipad 两者）的 IOS 8.1 中，我没有收到任何通知

【参考方案1】：

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)];
