iOS实现设备判断是否安装相关地图（百度、高德等）_IOS

前言

最近项目关于地图的，和朋友一起做的，他们用的高德地图，他做到半路有事，我来接手，结果我手机上没有安装高德地图，到我这边点击导航没啥反应，后来就查了一下，简单处理下，最终实现以下的需求：

点击导航，底部弹框，显示用户设备上所有的地图（一般就苹果自带的地图、百度地图、高德地图，当然了还有其他地图，个人感觉就这几个用的人比较多，其他的其实也类似），下面话不多说了，来一起看看详细的介绍吧。

具体做法如下：

1、plist文件进行相关的配置

lsapplicationqueriesschemes （这个一定不要写错，一定不要写错，一定不要写错，这个我是有教训的，说多了都是泪）这是一个数组，可以添加各地图的相关url scheme

常见的地图对应如下：

百度地图：baidumap
高德地图：iosamap
谷歌地图：comgooglemaps
腾讯地图：qqmap

iOS实现设备判断是否安装相关地图（百度、高德等）

你也可以直接直接复制以下代码到plist文件

				?

									<key>lsapplicationqueriesschemes</key>

									 <array>

									  <string>baidumap</string>

									  <string>iosamap</string>

									  <string>comgooglemaps</string>

									  <string>qqmap</string>

									 </array>

2.使用系统的api判断设备是否安装相关的地图应用程序

				?

									- (bool)canopenurl:(nsurl *)url ns_available_ios(3_0);

具体写发如下：

百度地图

				?

									[[uiapplication sharedapplication] canopenurl:[nsurl urlwithstring:@"baidumap://"]]

高德地图

				?

									[[uiapplication sharedapplication] canopenurl:[nsurl urlwithstring:@"iosamap://"]]

谷歌地图

				?

									[[uiapplication sharedapplication] canopenurl:[nsurl urlwithstring:@"comgooglemaps://"]]

腾讯地图

				?

									[[uiapplication sharedapplication] canopenurl:[nsurl urlwithstring:@"qqmap://"]]

该方法返回的bool值即可判断该设备有没有安装相关的地图应用

备注：苹果自带的地图是不需要判断的

这里贴一段代码，需要的时候稍微修改下即可

-(void)donavigationwithendlocation:(nsarray *)endlocation
{
nsmutablearray *maps = [nsmutablearray array];
//苹果原生地图-苹果原生地图方法和其他不一样
nsmutabledictionary *iosmapdic = [nsmutabledictionary dictionary];
iosmapdic[@"title"] = @"苹果地图";
[maps addobject:iosmapdic];
//百度地图
if ([[uiapplication sharedapplication] canopenurl:[nsurl urlwithstring:@"baidumap://"]]) {
nsmutabledictionary *baidumapdic = [nsmutabledictionary dictionary];
baidumapdic[@"title"] = @"百度地图";
nsstring *urlstring = [[nsstring stringwithformat:@"baidumap://map/direction?origin={{我的位置}}&destination=latlng:%@,%@|name=北京&mode=driving&coord_type=gcj02",endlocation[0],endlocation[1]] stringbyaddingpercentescapesusingencoding:nsutf8stringencoding];
baidumapdic[@"url"] = urlstring;
[maps addobject:baidumapdic];
}
//高德地图
if ([[uiapplication sharedapplication] canopenurl:[nsurl urlwithstring:@"iosamap://"]]) {
nsmutabledictionary *gaodemapdic = [nsmutabledictionary dictionary];
gaodemapdic[@"title"] = @"高德地图";
nsstring *urlstring = [[nsstring stringwithformat:@"iosamap://navi?sourceapplication=%@&backscheme=%@&lat=%@&lon=%@&dev=0&style=2",@"导航功能",@"nav123456",endlocation[0],endlocation[1]] stringbyaddingpercentescapesusingencoding:nsutf8stringencoding];
gaodemapdic[@"url"] = urlstring;
[maps addobject:gaodemapdic];
}
//谷歌地图
if ([[uiapplication sharedapplication] canopenurl:[nsurl urlwithstring:@"comgooglemaps://"]]) {

}

}
