本文介绍如何在Objective-C中调用JavaScript函数，包括使用_webView.stringByEvaluatingJavaScriptFromString方法执行简单的JavaScript函数调用及利用JavaScriptCore框架实现更复杂的功能。文中还提供了一个示例项目链接。

参考：http://stackoverflow.com/questions/14334047/how-to-call-javascript-function-in-objective-c

[_webView stringByEvaluatingJavaScriptFromString:@"methodName();"];
NSString* returnValue =[theWebView stringByEvaluatingJavaScriptFromString:@"myFunction('pass your parameter')"];

One can use JavaScriptCore framework to run JavaScript code from Objective-C.
#import <JavaScriptCore/JavaScriptCore.h>
JSContext *context = [[JSContext alloc] init];
[context evaluateScript: @"function greet(name){ return 'Hello, ' + name; }"];
JSValue *function = context[@"greet"];
JSValue* result = [function callWithArguments:@[@"World"]];
[result toString]; // -> Hello, World

Here is a demo:
