iOS的高德地图标注特定位置
在开发时有时候遇到项目里面需要展示公司的位置，这时如果导入百度地图什么的就太浪费资源，而且还占内存
这时只要调用自动高德地图的就行了
自己写一个控制器，导入框架
现在导入系统框架只要多打次就能出来了，没必要去link添加
1 #import "MapViewCtl.h" 2 #import <CoreLocation/CoreLocation.h> 3 #import <MapKit/MapKit.h> 4 5 //获取屏幕 宽度、高度 6 #define SCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width) 7 #define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height) 8 9 @interface MapViewCtl ()<MKMapViewDelegate> 10 { 11 MKMapView *mapView; 12 } 13 @property (nonatomic, readwrite) CLLocationCoordinate2D coordinate; 14 @end 15 16 @implementation MapViewCtl 17 18 - (void)viewDidLoad { 19 [super viewDidLoad]; 20 mapView = [[MKMapView alloc]initWithFrame:CGRectMake(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT)]; 21 22 mapView.mapType = MKMapTypeStandard; 23 24 CLLocationCoordinate2D location = CLLocationCoordinate2DMake(22, 111);//纬度，经度 25 float zoomLevel = 0.01; 26 MKCoordinateRegion region = MKCoordinateRegionMake(location, MKCoordinateSpanMake(zoomLevel, zoomLevel)); 27 [mapView setRegion:[mapView regionThatFits:region] animated:YES]; 28 [self.view addSubview:mapView]; 29 30 MKPointAnnotation *pointAnn = [[MKPointAnnotation alloc]init]; 31 pointAnn.coordinate = location; 32 pointAnn.title = @"某某有限公司"; 33 pointAnn.subtitle = @"某某地址"; 34 [mapView addAnnotation:pointAnn]; 35 [mapView selectAnnotation:pointAnn animated:YES]; 36 37 }
如果不知道怎么查经纬度的，可以参考这个 http://www.doc88.com/p-3157554808098.html
获取到的经纬度是 （经度，纬度），填到
CLLocationCoordinate2DMake(22, 111)时，要倒过来填 （纬度，经度）
