IOS 8已停止推送通知

Question

我已经使用支持推送通知功能的企业证书签署了我的应用程序。它工作得很好，当我把iphone更新到iOS 8时，推送通知停止了。经过调试和少量研究后，我了解到从iOS 8开始需要添加以下代码来检索推送令牌。

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) //>iOS8
{
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert) categories:nil];
            [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
}else {// <iOS8
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];

}

Add following callback methods,

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
     [application registerForRemoteNotifications];
}

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void(^)())completionHandler
{
    //handle the actions
}

然而，我们的应用程序的appstore版本不会遇到这个问题，而且一切都运行良好。是不是只在企业认证上有问题？

您忘记了一个线路代码：[[UIApplication sharedApplication] registerForRemoteNotifications];

如下所示：

if ([application respondsToSelector: selector (registerUserNotificationSettings :)]) {
      UIUserNotificationSettings * settings = [UIUserNotificationSettings settingsForTypes: UIUserNotificationTypeBadge | UIUserNotificationTypeAlert | UIUserNotificationTypeSound
                                                                               categories: nil ];
       [[UIApplication sharedApplication] registerUserNotificationSettings: settings];
       [[UIApplication sharedApplication] registerForRemoteNotifications];
   } else {
       [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
        UIRemoteNotificationTypeBadge |
        UIRemoteNotificationTypeAlert |
        UIRemoteNotificationTypeSound];

   }
