H5跳转到APP指定页面

1.设置urlschemes

urlschemes尽量设一个唯一的字符串，例如可以设为：iOS+公司英文名+ 项目工程名
比如我的设为iOSTencentTest，在浏览器中输入地址iOSTencentTest://即可跳转到我的app

2.跳转到指定页面

在使用iOSTencentTest://打开app会调用AppDelegate的代理方法

-(BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options

跳转指定页面在该方法中操作
iOSTencentTest://后面是可以添加参数的，例如iOSTencentTest://goodsDetails?id=xxxxx
goodsDetails可直接通过url.host获取
id=xxxxx 参数可直接通过url.query获取
可以根据自身需求去设置不同的host和参数。
