    Default Calling Objective-C Methods From JavaScript


    I have came across topic in apple documentation to access Objective C methods from javascript. But i'm not sure how things are working. Did anyone tried this ?.
    Could someone give more idea on this.

    You can call Objective C methods by invoking URL with custom protocol like document.location="mycustomprotocolname:functionName?param1=value1&param2=value2...".

    Then you must catch such navigation by delegate in UIWebView and if protocol for hyperlink not "http" but "mycustomprotocolname" then parse URL and call needed functions.
