How to call Objective-C from Javascript?
I’ve been asked by a friend to make him a very simple app that launches and then loads a full screen UIWebview and displays some html pages that are inside the app. No problem there.
He also asked me to call a url scheme, which will launch another app already installed on the device. I’ve done the url scheme stuff to launch an app before, that’s no problem.
What I don’t understand is how to go about getting the html to call a method in my app.
To summarize:
So my app will have native code that will:
a) Show a UIWebview which will display html pages embedded into the app.
b) A method that does the URL scheme stuff to launch another app.
Question: How can I call my method via the html(html button) pages?
Almost the same question but you should connect your scheme request in this method.
