原问题描述：
请问一下，检测ios的用户是否拒绝开启默认位置，能实现么？
我需要在实现检测结果，然后根据他们的选择显示不同的视图控制器。
解决方案：
假设你使用LocationManager,那么在delegate中有个方法是

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error

你来检测这个error.code是什么,具体参见apple官方文档Core Location Constants Reference中CLError部分

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;
