从混合应用程序从UIwebview访问iOS本机属性/方法
[英]Accessing iOS native properties/methods from UIwebview from a hybrid app
问题描述
I am not an iOS expert. 
我不是iOS专家。 I have a basic question, Is it possible to access/call any Objective C methods/properties from UI webview? 我有一个基本问题，是否可以从UI Webview访问/调用任何Objective C方法/属性？ In other words what would happen if i keep some objective C code in a HTML page and load it in UIwebview of an iOS hybrid app? 换句话说，如果我在HTML页面中保留一些目标C代码并将其加载到iOS混合应用程序的UIwebview中，将会发生什么？ Will the code execute? 代码会执行吗？

No - the code will not execute. 否-代码将不会执行。 What you're describing is an "injection" and, if it were possible, could wreak havoc in an app. 您所描述的是“注入”，并且如果可能的话，可能会对应用造成严重破坏。
Something I've done in the past is create an app with a UIWebView container (somewhat like you're describing) then pass back a response that my code can programmatically look for and handle. 我过去做过的事情是使用UIWebView容器创建一个应用程序（有点像您描述的那样），然后传回响应，我的代码可以以编程方式查找和处理。 This is of course possible by the fact I wrote both the app and the web back-end. 当然，这是因为我同时编写了应用程序和Web后端。
I'm sure there are other ways to do this but it has worked for me. 我敢肯定还有其他方法可以做到这一点，但是它对我有用。
