1.App->info中添加請求定位說明。
Privacy - Location Always Usage Description
Privacy - Location When In Use Usage Description

2.導(dǎo)入定位功能庫
App->Build Phases->Link Binary with Libraries->添加CoreLocation.framework

3.viewcontroller中導(dǎo)入corelocation.h

import <Corelocation/CoreLocation.h>

4.添加CLLocationManagerDelegate協(xié)議
@interface ViewController : UIViewController <CLLocationMangerDelegate>

5.初始化LocationManager對象
CLLocationManger *locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManger.desiredAccuracy = kCLLocationAccuracyBest;

6.請求定位權(quán)限
if([ locationManager responseToSelector:@selector(requestAlwaysAuthorization) ]){
[ locationManager requestAlwaysAuthorization];
}

7.開始定位
[locationManager startUpdateLocation];

8.定位結(jié)果返回的方法
失敗 ：-(void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error{}

成功：-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations{
}

CLLocation對象包含經(jīng)緯度信息

9.轉(zhuǎn)換經(jīng)緯度為文字地址
CLGeocoder *geocoder = [[CLGeocoder alloc] init];
[geocoder reverseGeocodeLocation:location preferredLocation:[NSLocale systemLocale] completionHandler:^(NSArray *placeMarks,NSError *error){

}

placeMarks包含CLPlaceMarker對象
if(placeMarks.count>0){
CLPlaceMarker *placeMarker = placeMarks[0]；
placemark.subThoroughfare;
placemark.thoroughfare;
placemark.postalCode;placemark.locality;
placemark.administrativeArea;
placemark.country；
}

10.停止獲取定位信息
[locationManager stopUpdatingLocation];
