Как исправить ошибку CLLocation Manager с ошибкой местоположения?

Question

Я пытаюсь заставить работать менеджер CLLocation, но он постоянно выдает мне сообщение об ошибке locationManager failed with error=Error Domain=kCLErrorDomain Code=0 "The operation couldn’t be completed. (kCLErrorDomain error 0.)", Я посмотрел на stackru для ответов, и я обнаружил, что This error also occurs if you have Scheme/Edit Scheme/Options/Allow Location Simulation checked but don't have a default location set. Применяя это, он поднял синюю точку с установленным местоположением по умолчанию. Но я хочу текущее местоположение пользователя. У меня есть код для этого, но, похоже, не работает должным образом, следовательно, ошибка, обнаруживающая текущего пользователя.

Несколько вещей, одна из которых NSLocationAlwaysUsageDescription добавлена ​​в файл info.plist ваших приложений? Два вы установили местоположение в симуляторе? (Debug->Location). В-третьих, вы должны запросить дополнительную авторизацию для использования основного местоположения в ios8.

if ([locationManager respondsToSelector:@selector(requestAlwaysAuthorization)])
[locationManager requestAlwaysAuthorization];
