如何判断当前App是否允许使用系统定位功能
如题解答：利用CLLocationManager的一个类方法+ (CLAuthorizationStatus)authorizationStatus
// CLAuthorizationStatus是一个枚举值：
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;所以，一切变得简单了 // 判断本地定位服务开启
if( == kCLAuthorizationStatusDenied){
// 提示用户开启定位服务，PS：iOS8系统会自动检测额
;
