Question

我的应用程序由于此行[application registerForRemoteNotifications];而一直崩溃，我只能将它放在下面的位置才能工作。推送笔记不发送，因为我没有把它放在正确的位置。

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
        UIUserNotificationSettings *notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];

        [application registerUserNotificationSettings:notificationSettings];
    } else {
        UIRemoteNotificationType notificationTypes = UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound;
        [application registerForRemoteNotificationTypes:notificationTypes];

        [application registerForRemoteNotifications];
    }

请帮我注册通知，以便设备让他们开启Parse它说推送已发送。任何想法？

请参阅崩溃消息

我认为当我发表评论时，这一行是空的[currentInstallation setObject:[PFUser currentUser].objectId forKey:@"userId"];。

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    PFInstallation *currentInstallation = [PFInstallation currentInstallation];
    [currentInstallation setObject:[[PFUser currentUser] objectId] forKey:@"userId"];
    [currentInstallation setDeviceTokenFromData:deviceToken];
    [currentInstallation saveInBackground];

我该如何解决？

谢谢，
