IOS实现自动定位和手动选择城市功能

IOS自动定位使用的是高德地图SDK

在高德开放平台http://lbs.amap.com/api/ios-sdk/down/ 下载2D地图SDK和搜索SDK

将SDK导入工程内按照高德的配置说明进行配置项目

最后需要提醒在高德的SDK中有些文件夹使用的是快捷方式，如果你在你本地的工程编译通过, 但可能在你的服务端自动打包的时候不能自动编译通过

需要将那些快捷方式的文件夹用真实文件夹替换掉就可以了。

在工程中导入

#import "MAMapKit/MAMapKit.h"

#import "AMapSearchKit/AMapCommonObj.h"

#import "AMapSearchKit/AMapSearchAPI.h"

在Controller中使用初始化地图服务

#pragma mark  MAMAP init AND 定位回调

    if (![CLLocationManager locationServicesEnabled]) {

        [PXAlertView showAlertWithTitle:@"提示" message:[NSString stringWithFormat:@"请开启定位:设置 > 隐私 > 位置 > 定位服务"] completion:^(BOOL cancelled, NSInteger buttonIndex) {

        }];

        return;

    }

    else if([CLLocationManager authorizationStatus] == kCLAuthorizationStatusDenied){

        [PXAlertView showAlertWithTitle:@"提示" message:[NSString stringWithFormat:@"定位失败，请开启定位:设置 > 隐私 > 位置 > 定位服务 下 应用"] completion:^(BOOL cancelled, NSInteger buttonIndex) {

        }];

        return;

    }
