  • 0

I am writing a function that collaborates with a JS web page. I use UIWebView to contain the webpage and then situation has become complicated when I want the web page to communicate with my app.

Calling a javascript function in UIWebView is easy by using the – stringByEvaluatingJavaScriptFromString: method

But is there any easier way to call an obj-c function in the web page, using javascript? I tried using the UIWebView delegate method, but I think it’s too hacky.

Any advice?

    I guess using delegate is the only (one or two) methodology you can use in iOS WebView. But there are several wrappers that may help you easy out.

    1. EasyJSWebView – This replicates the development experience as in Android. In Android, you can simply use the addJavascriptInterface() method in WebView to bridge the Javascript to Java. EasyJSWebView provides both sync-style and async-style for getting the return value from Objective-C methods.

    2. WebViewJavascriptBridge – The code may look a little bit like socket programming. You can pass data to and fro between the “server” in Objective-C and the “client” in Javascript.

    3. GAJavaScript – This may provide a better DOM manipulation experience.

    Take a look at all of them and choose one that fits your need.
