ios - Send javascript function to objective-C using JavascriptCore -

i'm trying send javascript function object objective-c via javascriptcore, leveraging jsexport protocol. have function declared in objective-c, conforming jsexport follows:

(class view) + (void) newwithfunc:(id)func { nslog(@" %@ ", func); }

after declaring class, seek phone call function above javascript function object parameter

jsvalue *val; val = [context evaluatescript:@"var mufunc = function() { self.value = 10; };"]; val = [context evaluatescript:@"mufunc;"]; nslog(@" %@", val); //prints 'function() { self.value = 10; }', seems correct. val = [context evaluatescript:@"var view = view.newwithfunc(mufunc);"];

when lastly phone call made, parameter sent objective-c method of type 'nsdictionary', doesn't seem valuable if phone call function objective-c @ later point in time. possible javascriptcore?

please mark tayschrenn's answer correct. don't know how knew or it's documented, figured out trial , error:

- (void)newwithfunc: (jsvalue*)func { [func callwitharguments:@[]]; // invoke js func no params }

declaring parameter (id)func apparently causes javascript-cocoa bridge convert nsdictionary (as noticed), rendering unusable callable jsvalue.
