我是靠谱客的博主 谦让歌曲,这篇文章主要介绍iOS 高德地图仿微信发送实时位置,现在分享给大家,希望可以做个参考。

最近项目中要写一个微信那种发送位置的功能。具体功能在于:

- 定位到当前位置

- 可定位当前位置附近的Poi

- 可自行搜索目标位置,并展示附近的poi

- 选择当前位置或者选择目标位置进行发送

一.准备工作

1.首先去高德地图官网下载相关的SDK(如下图):

2.按照高德地图官网的步骤继续添加所需要的依赖库

3.根据项目的bundleID前往高德地图API中创建引用并申请相关的key

高德地图应用管理后台

到这一步前期的准备工作基本差不多了,当然,我这写的不是很具体,详细的引入高德地图SDK还需要耐心按照高德地图官网SDK一步步的去操作

二.代码部分

1.初始化高德地图SDK

在AppleDelegate中引入相关头文件,从高德地图应用管理中找到该应用对用的key值,进行高德地图SDK的初始化操作。直接贴代码部分:

#import "AppDelegate.h" #import "ViewController.h" #import <AMapLocationKit/AMapLocationKit.h> #import <AMapFoundationKit/AMapFoundationKit.h> static NSString *APIKey = @"a1500980e29b7ca7612a46c19e0d2e3a"; @interface AppDelegate () @end @implementation AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds]; [self.window makeKeyAndVisible]; self.window.rootViewController = [[UINavigationController alloc] initWithRootViewController:[ViewController new]]; [AMapServices sharedServices].apiKey = APIKey; return YES; }

2.定位到用户当前位置

在你需要定位的类中引入与地图相关的头文件

初始化地图view:

定位成功之后展示大头针到当前位置(如果一直不显示大头针,检查一下自己是否导入了高德地图的资源文件):

地图的代理方法等:

- (void)mapView:(MAMapView *)mapView regionDidChangeAnimated:(BOOL)animated{ [self.mapView removeAnnotations:self.mapView.annotations]; CLLocationCoordinate2D centerCoordinate = mapView.region.center; self.currentLocationCoordinate = centerCoordinate; MAPointAnnotation * centerAnnotation = [[MAPointAnnotation alloc] init]; centerAnnotation.coordinate = centerCoordinate; centerAnnotation.title = @""; centerAnnotation.subtitle = @""; [self.mapView addAnnotation:centerAnnotation]; //主动选择地图上的地点 if (!self.isSelectedAddress) { [self.tableView setContentOffset:CGPointMake(0,0) animated:NO]; self.selectedIndexPath=[NSIndexPath indexPathForRow:0 inSection:0]; self.request.location = [AMapGeoPoint locationWithLatitude:centerCoordinate.latitude longitude:centerCoordinate.longitude]; self.currentPage = 1; self.request.page = self.currentPage; [self.mapSearch AMapPOIAroundSearch:self.request]; } self.isSelectedAddress = NO; }

包括主动选择地图上的点然后进行附近的搜索,可自定义搜索的内容,定位成功之后用户可以获取到当前的经纬度地址等一系列信息。详细的代码有点多就不一一贴出来了,需要的同学可以点击下面的github地址去下载体验。
