CLAuthorizationStatus status = [CLLocationManager authorizationStatus];
    if (status == kCLAuthorizationStatusNotDetermined || status == kCLAuthorizationStatusDenied)
    {
        // 第一次安装，尚未做出选择
        [self.manager requestWhenInUseAuthorization];
    }
老师，checkLocationAuthorization 方法里的这段逻辑是不是可以归纳到代理方法里- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status
里，因为怎么样最后都要去执行代理方法
