1.在高德地图官网上注册 成功开发者
2.添加一个应用 注册一个appKey
3.用cocoa pod 中 写入 pod 'AMapLocation' #定位SDK 下载SDK

4. 需要在info.plist中追加 NSLocationWhenInUseUsageDescription 或NSLocationAlwaysUsageDescription 字段，以申请定位权限。
   <key>NSAppTransportSecurity</key>
   <dict>
   <key>NSAllowsArbitraryLoads</key>
   <true/>
   </dict>
   5.在appDelegate中 加入

import <AMapFoundationKit/AMapFoundationKit.h>

//注册 apiKey

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [AMapServices sharedServices].apiKey = @"29cd402f1007bb54d5e1f2857666c71f";
    return YES;
}

6. 在需要的地方 开始定位

#import <AMapLocationKit/AMapLocationKit.h>
@interface ViewController ()<AMapLocationManagerDelegate>
@property(nonatomic,strong)AMapLocationManager *manager;
@end

- (void)amapLocationManager:(AMapLocationManager *)manager didUpdateLocation:(CLLocation *)location
{
    CLGeocoder *geocoder = [[CLGeocoder alloc] init];
    [geocoder reverseGeocodeLocation:location completionHandler:^(NSArray<CLPlacemark *> * _Nullable placemarks, NSError * _Nullable error) {
        if (placemarks.count > 0) {
            
            CLPlacemark *placemark = [placemarks objectAtIndex:0];
            
            NSLog(@"%@",placemark);
            //将获得的所有信息显示到label上
            NSLog(@"placemark.name : %@", placemark.name);
            //获取城市
            NSLog(@"城市 = %@",placemark.locality);
            //获取国家
            NSLog(@"国家 = %@",placemark.country);
            //获取省份
            NSLog(@"省 = %@",placemark.administrativeArea);
            self.resultLab.text = [NSString stringWithFormat:@"%@ %@ %@",placemark.country,placemark.administrativeArea,placemark.locality];
        }
    }];

}

- (IBAction)startLocation:(UIButton *)sender {
    [self.manager startUpdatingLocation];
}
- (IBAction)endLocation:(UIButton *)sender {
   [self.manager stopUpdatingLocation]; //停止持续定位
}
