地图实现地点查找和导航

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

<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>跟踪定位代理</p><p style="margin-top: 0px; margin-bottom: 0px; font-size: 14px; line-height: normal; font-family: Menlo;">- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations</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;">    CLLocation *location = [locations firstObject]; // <span style="line-height: normal; font-family: 'Heiti SC Light';">取出第一个位置</span></p><p style="margin-top: 0px; margin-bottom: 0px; font-size: 14px; line-height: normal; font-family: Menlo;">    CLLocationCoordinate2D coordinate = location.coordinate; // <span style="line-height: normal; font-family: 'Heiti SC Light';">位置坐标</span></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';">经度：</span>%f,<span style="line-height: normal; font-family: 'Heiti SC Light';">纬度：</span>%f,<span style="line-height: normal; font-family: 'Heiti SC Light';">海拔：</span>%f,<span style="line-height: normal; font-family: 'Heiti SC Light';">航向：</span>%f,<span style="line-height: normal; font-family: 'Heiti SC Light';">行走速度：</span>%f",coordinate.longitude,coordinate.latitude,location.altitude,location.course,location.speed);</p><p style="margin-top: 0px; margin-bottom: 0px; font-size: 14px; line-height: normal; font-family: Menlo;">    _jinddu = coordinate.longitude;</p><p style="margin-top: 0px; margin-bottom: 0px; font-size: 14px; line-height: normal; font-family: Menlo;">    _weidu = coordinate.latitude;</p><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><span style="line-height: normal; font-family: Menlo;">//</span>如果不需要实时定位，使用完即使关闭定位服务</p><p style="margin-top: 0px; margin-bottom: 0px; font-size: 14px; line-height: normal; font-family: Menlo;">    [_locationManager stopUpdatingLocation];</p><p style="margin-top: 0px; margin-bottom: 0px; font-size: 14px; line-height: normal; font-family: Menlo;">}</p>

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];}];}];
}
