应该场景描述：后台返回给我的地址，我需要将地址转成 经纬度，进行导航。
记录原因：网上相关文档，因为版本原因，更新不全面，无法快速实现功能
使用步骤：
- 项目中导入 高德地图的 SDK ，我用的是pod, 在pod文件中加入下面代码，并执行 pod install .
#高德地图
pod 'AMapSearch'
pod 'AMapLocation'
pod 'AMapNavi'
- 在需要使用的 XXX controller.h 导入头文件
#import <AMapNaviKit/MAMapKit.h> // 创建地图需要
#import <AMapFoundationKit/AMapFoundationKit.h>
#import <AMapSearchKit/AMapSearchKit.h>
- XXX controller.m 中遵循 代理
@interface XXXMapController ()
<MAMapViewDelegate,
AMapSearchDelegate>
@end
- 功能代码
- (void)viewDidLoad {
[super viewDidLoad];
// 隐藏navBar
[self navBarNeedHidden:YES andAnimation:NO];
[self configSubViews];
}
-(void)configSubViews {
[AMapServices sharedServices].enableHTTPS = YES;
// 配置用户APP Key --> 自己在高德平台去申请
[[AMapServices sharedServices] setApiKey:@"xxxxxxxxxxxxxxxxxxx"];
///初始化地图
self.maMapView = [[MAMapView alloc] initWithFrame:self.mapBGView.bounds];
self.maMapView.zoomLevel = 14.5f;
self.search = [[AMapSearchAPI alloc] init];
// self.maMapView.delegate = self;
self.search.delegate = self;
//发起正向地理编码
AMapGeocodeSearchRequest *searchRequest = [[AMapGeocodeSearchRequest alloc] init];
// 将字符串的地址 通过正向地理编码转换为 经纬度坐标点
searchRequest.address = self.addressStr;
[self.search AMapGeocodeSearch: searchRequest];
// 发起逆向地理编码
// AMapReGeocodeSearchRequest *searchRequest = [[AMapReGeocodeSearchRequest alloc] init];
// searchRequest.location.latitude = xx.xxxxxx;
// searchRequest.location.longitude = xx.xxxxxx;
// [self.search AMapReGoecodeSearch:searchRequest];
///把地图添加至view
[self.mapBGView addSubview:self.maMapView];
}
