Apple Watch coreLocation error *** [ - CLLocationManager requestLocation]

中的斷言失敗我試圖用coreLocation在Apple Watch上獲取用戶當前位置。每當我運行-[CLLocationManager requestLocation]，該應用程序退出並給出以下錯誤。Apple Watch coreLocation error *** [ - CLLocationManager requestLocation]

這是我的代碼：

locationManager = [[CLLocationManager alloc] init]; 
locationManager.delegate = self; 
[locationManager requestWhenInUseAuthorization]; 
[locationManager requestLocation];

如果你有更好的方法來獲取用戶的位置，請讓我知道爲好。

應該有更多的錯誤消息告訴你什麼是問題 – dan

這個錯誤信息並沒有什麼意義，你在調試器中做了些什麼來引起這個錯誤？也許從斷點處記錄某些東西？ – dan

它不會解決問題，但您現在應該能夠看到真正的錯誤消息 – dan

根據錯誤消息，'Delegate must respond to locationManager:didUpdateLocations:'我必須在我的委託中實現locationManager:didUpdateLocations:和locationManager:didFailWithError:以便使用requestLocation。

我不知道我們是否可以在蘋果手錶中使用位置管理器。我認爲我們需要回到父應用來使用手錶連接來獲取CLLocation。

其實，我可以。在上面的評論中使用Dan的建議，我實現了委託方法，一切正常。換句話說，問題解決了！ – NeilNie
