iOS之获取经纬度并通过反向地理编码获取详细地址

_locationManager = [[CLLocationManager alloc] init];

    //期望的经度

    _locationManager.desiredAccuracy = kCLLocationAccuracyBest;

    //大约变化100米更新一次

    _locationManager.distanceFilter = 100;

    //认证NSLocationAlwaysUsageDescription

    if ([[UIDevice currentDevice] systemVersion].doubleValue > 8.0) {//如果iOS是8.0以上版本

        if ([_locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) {//位置管理对象中有requestAlwaysAuthorization这个方法

            //运行

            [_locationManager requestAlwaysAuthorization];

        }

    }

    _locationManager.delegate = self;

//获取经纬度和详细地址

    CLLocation *location = [locations lastObject];
