Utilizing JavaScript functions in an iOS native application

I have a specific requirement for my IOS native app to call a remote server javascript function. Here is an example scenario:

In Objective-C, I am creating a UI with two textfields, one button, and one label. I input two integers into the textfields, let's say 5 and 7, and upon clicking the button I expect the sum (12) to be displayed on the label.

The calculation will be performed on a remote server using javascript: The javascript file is located on a remote web server at

Here is the code inside the javascript file:

function sum(x,y) {
 var z = parseInt(x)+parseInt(y);
 return z;
}

How should the Objective-C code look like?
