檢測ios的使用者是否拒絕開啟預設位置的實現

原問題描述：請問一下，檢測ios的使用者是否拒絕開啟預設位置，能實現嗎？我需要在實現檢測結果，然後根據他們的選擇顯示不同的視圖控制器。解決方案：假設你使用LocationManager,那麼在delegate中有個方法是[plain]  - (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error   你來檢測這個error.code是什麼,具體參見apple官方文檔Core Location Constants Reference中CLError部分[plain]  enum {  kCLErrorLocationUnknown  = 0,         // location is currently unknown, but CL will keep trying  kCLErrorDenied,                       // CL access has been denied (eg, user declined location use)  kCLErrorNetwork,                      // general, network-related error  kCLErrorHeadingFailure,               // heading could not be determined  kCLErrorRegionMonitoringDenied,       // Location region monitoring has been denied by the user  kCLErrorRegionMonitoringFailure,      // A registered region cannot be monitored  kCLErrorRegionMonitoringSetupDelayed, // CL could not immediately initialize region monitoring  kCLErrorRegionMonitoringResponseDelayed, // While events for this fence will be delivered, delivery will not occur immediately  kCLErrorGeocodeFoundNoResult,         // A geocode request yielded no result  kCLErrorGeocodeFoundPartialResult,    // A geocode request yielded a partial result  kCLErrorGeocodeCanceled,              // A geocode request was cancelled  kCLErrorDeferredFailed,               // Deferred mode failed  kCLErrorDeferredNotUpdatingLocation,  // Deferred mode failed because location updates disabled or paused  kCLErrorDeferredAccuracyTooLow,       // Deferred mode not supported for the requested accuracy  kCLErrorDeferredDistanceFiltered,     // Deferred mode does not support distance filters  kCLErrorDeferredCanceled,             // Deferred mode request canceled a previous request  };  typedef NSInteger CLError;
