二、iOS集成高德定位SDK

APIkey申请略过，代码参考官方demo

1. AMapUtil.h
   定义AMapUtil 接口，reGeocodeAction为外部的实例方法

#import <AMapLocationKit/AMapLocationKit.h>
@interface AMapUtil : NSObject
@property (nonatomic, strong) AMapLocationManager *locationManager;
-(void)reGeocodeAction;
@end

2. AMapUtil.m
   AMapUtil接口实现，本demo只调用 进行单次带逆地理定位请求

#import <Foundation/Foundation.h>
#import "AMapUtil.h"
#define DefaultLocationTimeout 10
#define DefaultReGeocodeTimeout 5
@interface AMapUtil () <AMapLocationManagerDelegate>
@property (nonatomic, copy) AMapLocatingCompletionBlock completionBlock;
@end
@implementation AMapUtil
#pragma mark - Action Handle
-(void)configLocationManager
{
    self.locationManager = [[AMapLocationManager alloc] init];
    [self.locationManager setDelegate:self];
    //设置期望定位精度
    [self.locationManager setDesiredAccuracy:kCLLocationAccuracyHundredMeters];    
    //设置不允许系统暂停定位
    [self.locationManager setPausesLocationUpdatesAutomatically:NO];    
    //设置允许在后台定位
    [self.locationManager setAllowsBackgroundLocationUpdates:YES];
    //设置定位超时时间
    [self.locationManager setLocationTimeout:DefaultLocationTimeout];    
    //设置逆地理超时时间
    [self.locationManager setReGeocodeTimeout:DefaultReGeocodeTimeout];
}
-(void)cleanUpAction
{
    //停止定位
    [self.locationManager stopUpdatingLocation];    
    [self.locationManager setDelegate:nil];    
}
-(void)reGeocodeAction
{
    [self initCompleteBlock];
    [self configLocationManager];   
    //进行单次带逆地理定位请求
    [self.locationManager requestLocationWithReGeocode:YES completionBlock:self.completionBlock];
}
-(void)locAction
{
    //进行单次定位请求
    [self.locationManager requestLocationWithReGeocode:NO completionBlock:self.completionBlock];
}

#pragma mark - Initialization
-(void)initCompleteBlock
{
    self.completionBlock = ^(CLLocation *location, AMapLocationReGeocode *regeocode, NSError *error)
    {
        if (error)
        {
            NSLog(@"locError:{%ld - %@};", (long)error.code, error.localizedDescription);            
            //如果为定位失败的error，则不进行后续操作
            if (error.code == AMapLocationErrorLocateFailed)
            {
                return;
            }
        }        
        //得到定位信息
        if (location)
        {
            NSLog(@"%@",location);
            NSLog(@"%@",regeocode);            
            if (regeocode)
            {
                NSLog(@"%@ \n %@-%@-%.2fm", regeocode.formattedAddress,regeocode.citycode, regeocode.adcode, location.horizontalAccuracy);
            }
            else
            {
                NSLog(@"lat:%f;lon:%f \n accuracy:%.2fm", location.coordinate.latitude, location.coordinate.longitude, location.horizontalAccuracy);
            }
        }
    };
}
#pragma mark - Life Cycle
-(void)dealloc
{
    [super dealloc];
    [self cleanUpAction];
    
    self.completionBlock = nil;
}
@end

3. 项目结构

   
   

4. 调用
   在AppDelegate.m设置APIKey，申请的APIKey在APIKey.h

-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [AMapServices sharedServices].apiKey = (NSString *)APIKey;
}

在方法中调用

AMapUtil *amapUtil = [[AMapUtil alloc] init];
    [amapUtil reGeocodeAction ];
