如何监控 [CLLocationManager locationServicesEnabled] 何时更改？我需要类似 delegate 或 notification 的东西。
最佳答案
使用 CLLocationManager 的 delagte 方法
- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status
这些是文档中的 CLAuthorizationStatus 描述:
> typedef enum {
> kCLAuthorizationStatusNotDetermined = 0, // User has not yet made a choice with regards to this application
> kCLAuthorizationStatusRestricted, // This application is not authorized to use location services. Due
> // to active restrictions on location services, the user cannot change
> // this status, and may not have personally denied authorization
> kCLAuthorizationStatusDenied, // User has explicitly denied authorization for this application, or
> // location services are disabled in Settings
> kCLAuthorizationStatusAuthorized // User has authorized this application to use location services
} CLAuthorizationStatus;
