我的iOS應用程序在Xcode 4.6和iOS 6.1上完成了98％，工作正常。更新爲Xcode 5後的問題
但隨後問題開始，當我嘗試更新我的Xcode 5版和SDK到iOS 7
當我嘗試在Xcode中5，但與iOS 6.1也將繼續工作，正常運行的應用程序，但是當我試圖在SDK 7上運行我有這些問題：

請寄出導致這個堆棧跟蹤的代碼。 – dasblinkenlight
可能是因爲您沒有在項目中引用/包括Core Location框架。根據本指南，「位置服務由Core Location框架提供，地圖由Map Kit框架提供。」堆棧跟蹤顯示MapKit，但沒有CoreLocation。 https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/LocationAwarenessPG/Introduction/Introduction.html –
