环境：系统版本：

OSX 10.10.2

Xcodel版本：7.1.1

功能：用自带地图实现查找，导航

1.首先需要在info.plist中添加NSLocationWhenInUseUsageDescription和NSLocationAlwaysUsageDescription两个属性

导入CoreLocation.framework框架

2.创建CLLocationManager类，启动定位功能

// 定位管理
    self.locationManager = [[CLLocationManager alloc]init];
    if (![CLLocationManager locationServicesEnabled]) {
        NSLog(@"定位服务当前未打开");
        return;
    }
    // 请求用户授权
    if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined) {
        [self.locationManager requestWhenInUseAuthorization];
    }else if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusAuthorizedWhenInUse){
        // 设置代理
        self.locationManager.delegate = self;
        // 设置定位精度
        self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;
        // 定位频率，每隔多少米定位一次
        CLLocationDistance distance = 10.0; // 十米定位一次
        self.locationManager.distanceFilter = distance;
        // 启动跟踪定位
        [self.locationManager startUpdatingLocation];
    }

遵守CLLocationManagerDelegate代理，实现跟踪定位

2.根据坐标取得地名

<p style="margin-top: 0px; margin-bottom: 0px; font-size: 14px; line-height: normal; font-family: 'Heiti SC Light';"><span style="line-height: normal; font-family: Menlo;">// </span>根据坐标取得地名</p><p style="margin-top: 0px; margin-bottom: 0px; font-size: 14px; line-height: normal; font-family: Menlo;">-(void)getAddressByLatitude:(CLLocationDegrees)latitude longitude:(CLLocationDegrees)longitude{</p><p style="margin-top: 0px; margin-bottom: 0px; font-size: 14px; line-height: normal; font-family: Menlo;">    //<span style="line-height: normal; font-family: 'Heiti SC Light';">反地理编码</span></p><p style="margin-top: 0px; margin-bottom: 0px; font-size: 14px; line-height: normal; font-family: Menlo;">    CLLocation *location=[[CLLocation alloc]initWithLatitude:latitude longitude:longitude];</p><p style="margin-top: 0px; margin-bottom: 0px; font-size: 14px; line-height: normal; font-family: Menlo;">    [_geocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error) {</p><p style="margin-top: 0px; margin-bottom: 0px; font-size: 14px; line-height: normal; font-family: Menlo;">        CLPlacemark *placemark=[placemarks firstObject];</p><p style="margin-top: 0px; margin-bottom: 0px; font-size: 14px; line-height: normal; font-family: Menlo;">        NSLog(@"<span style="line-height: normal; font-family: 'Heiti SC Light';">详细信息</span>:%@",placemark.addressDictionary);</p><p style="margin-top: 0px; margin-bottom: 0px; font-size: 14px; line-height: normal; font-family: Menlo;">    }];</p><p style="margin-top: 0px; margin-bottom: 0px; font-size: 14px; line-height: normal; font-family: Menlo;">}</p>

3.根据地名确定地理坐标

<p style="margin-top: 0px; margin-bottom: 0px; font-size: 14px; line-height: normal; font-family: Menlo;">-(void)getCoordinateByAddress:(NSString *)address{</p><p style="margin-top: 0px; margin-bottom: 0px;

使用苹果自带地图

1.根据单个地名在地图上定位

-(void)location{
    //地理编码
    [_geocoder geocodeAddressString:@"上海市" completionHandler:^(NSArray *placemarks, NSError *error) {
        CLPlacemark *clPlacemark=[placemarks firstObject];//获取第一个地标
        MKPlacemark *mkplacemark=[[MKPlacemark alloc]initWithPlacemark:clPlacemark];//定位地标转化为地图的地标
        NSDictionary *options=@{MKLaunchOptionsMapTypeKey:@(MKMapTypeStandard)};
        MKMapItem *mapItem=[[MKMapItem alloc]initWithPlacemark:mkplacemark];
        [mapItem openInMapsWithLaunchOptions:options];
    }];
}

2.定位多个地名

- (void)listPlacemark
{
    //根据“北京市”进行地理编码
    [_geocoder geocodeAddressString:@"北京市" completionHandler:^(NSArray *placemarks, NSError *error) {
        CLPlacemark *clPlacemark1=[placemarks firstObject];//获取第一个地标
        MKPlacemark *mkPlacemark1=[[MKPlacemark alloc]initWithPlacemark:clPlacemark1];
        
        //注意地理编码一次只能定位到一个位置，不能同时定位，所在放到第一个位置定位完成回调函数中再次定位
        [_geocoder geocodeAddressString:@"郑州市" completionHandler:^(NSArray *placemarks, NSError *error) {
            
            CLPlacemark *clPlacemark2=[placemarks firstObject];//获取第一个地标
            MKPlacemark *mkPlacemark2=[[MKPlacemark alloc]initWithPlacemark:clPlacemark2];
            NSDictionary *options=@{MKLaunchOptionsMapTypeKey:@(MKMapTypeStandard)};
            //MKMapItem *mapItem1=[MKMapItem mapItemForCurrentLocation];//当前位置
            MKMapItem *mapItem1=[[MKMapItem alloc]initWithPlacemark:mkPlacemark1];
            MKMapItem *mapItem2=[[MKMapItem alloc]initWithPlacemark:mkPlacemark2];
            [MKMapItem openMapsWithItems:@[mapItem1,mapItem2] launchOptions:options];
        }];
    }];
}

3.实现导航功能

-(void)turnByTurn{
    //根据“北京市”地理编码
    [_geocoder geocodeAddressString:@"北京市" completionHandler:^(NSArray *placemarks, NSError *error) {
        CLPlacemark *clPlacemark1=[placemarks firstObject];//获取第一个地标
        MKPlacemark *mkPlacemark1=[[MKPlacemark alloc]initWithPlacemark:clPlacemark1];
        //注意地理编码一次只能定位到一个位置，不能同时定位，所在放到第一个位置定位完成回调函数中再次定位
        [_geocoder geocodeAddressString:@"郑州市" completionHandler:^(NSArray *placemarks, NSError *error) {
            CLPlacemark *clPlacemark2=[placemarks firstObject];//获取第一个地标
            MKPlacemark *mkPlacemark2=[[MKPlacemark alloc]initWithPlacemark:clPlacemark2];
            NSDictionary *options=@{MKLaunchOptionsMapTypeKey:@(MKMapTypeStandard),MKLaunchOptionsDirectionsModeKey:MKLaunchOptionsDirectionsModeDriving};
            //MKMapItem *mapItem1=[MKMapItem mapItemForCurrentLocation];//当前位置
            MKMapItem *mapItem1=[[MKMapItem alloc]initWithPlacemark:mkPlacemark1];
            MKMapItem *mapItem2=[[MKMapItem alloc]initWithPlacemark:mkPlacemark2];
            [MKMapItem openMapsWithItems:@[mapItem1,mapItem2] launchOptions:options];
        }];
    }];
}
