iOS 弹出系统地址权限弹窗

 需求： 点击按钮的时候，判断是否可以弹出系统的地址权限弹窗，如果可以则弹出，如果不可以则跳转到系统设置

我们需要根据当前的 CLAuthorizationStatus来判断是否能弹出弹窗

当状态为kCLAuthorizationStatusNotDetermined的时候可以弹出

- (void)clickLocation
{
    
    CLAuthorizationStatus status = [CLLocationManager authorizationStatus];
    if (status == kCLAuthorizationStatusNotDetermined) {
        self.manager = [[CLLocationManager alloc] init];
        [self.manager requestWhenInUseAuthorization];
        self.manager.delegate = self;
    } else {
        [self goSyemtmSetting];
    }
}

然后我们要遵循 CLLocationManagerDelegate 代理并实现代理方法 didChangeAuthorizationStatus 是

权限有改动的代理

#pragma mark - CLLocationManagerDelegate
- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status
{
    [self reloadData];
}
