Call objective-c methods class from Javascript using UIWebview?

Question

My requirement is: I need to initialize a specific objective-c class and call its method from javscript using UIWebview like below eg:

I have an objective-c class called "Calculator" which has the following methods

@interface Calculator : NSObject {
}
@property (nonatomic, retain) start;
@property (nonatomic, retain) add:(NSInteger) a with:(NSInteger) b;
@property (nonatomic, retain) subract:(NSInteger) a by:(NSInteger) b;;

@end;

I have a UIWebview, in which I am loading HTML with JS. Here, I have a JS script function like

function callNativeClass() {

window.calc.start;

}

"calc" is the instance or namespace of the class. I need to call the start method from JS.

Can you please tell me, is there any option to call native objective-c class like PhoneGap?

Phonegap does this. Download the framework from phonegap.com. You can create a custom plugin very easily to call the methods in Objective C file. Try this
