Я знаю, что могут быть проблемы при использовании одного и того же устройства для производства и разработки, в качестве альтернативы, когда речь идет о Push-уведомлениях и концентраторах уведомлений в Azure.
Способ, которым я настроил, для iOS такой:
- У меня есть один концентратор уведомлений в Azure, настроенный для производства, подключенный к одному веб-API, расположенному в Azure.
- Другой концентратор уведомлений в Azure, настроенный для разработки, подключен к другому веб-API, размещенному в Azure..
Когда я работаю с приложением в разработке, в AppDelegate.cs я просто регистрируюсь в центре разработки, например:
var client = new MobileServiceClient(AppConstants.AZURE_DEVELOPMENT_WEB_API_URL);
Когда приложение готово к производству, в AppDelegate.cs я регистрируюсь в центре уведомлений о работе, например:
var client = newMobileServiceClient(AppConstants.AZURE_PRODUCTION_WEB_API_URL);
Конечно, я изменяю ключ aps-среды Entitlements.plist для разработки или производства в зависимости от ситуации.
Некоторое время это работало хорошо, но теперь я получаюrror в этой строке:
try
{
// exception is triggered here:
await client.GetPush().RegisterAsync(deviceToken, templates);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
И ошибка такова:

Итак, яЯ почти уверен, что есть проблема с идентификатором установки, вызванным тем, что я скачал приложение из магазина, а затем использовал тот же iPhone в разработке, и для push-уведомлений есть смешанный идентификатор установки / регистрации, но что делать дальше?Как я могу сбросить идентификатор установки?
Любые предложения приветствуются.
