朋友是做安卓的，她在html中成功回调了安卓的方法，问我ios怎么回调。这个东东没做过啊，赶紧问度娘，原来要用到JavaScriptCore.framework.

啥都不说了，先贴代码
ViewController.h

#import <UIKit/UIKit.h>#import <JavaScriptCore/JavaScriptCore.h>@interface ViewController : UIViewController@property (strong, nonatomic) IBOutlet UIWebView *webView;@end

ViewController.m

#import "ViewController.h"@interface ViewController ()@end@implementation ViewController- (void)viewDidLoad {    [super viewDidLoad];    NSString *path = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html"];    [_webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:path]]];    JSContext *context = [_webView valueForKeyPath:@"documentView.webView.mainFrame.javaScriptContext"];    context[@"callOC"] = ^()    {        NSLog(@"+++++++callOC+++++++");    };}- (void)didReceiveMemoryWarning {    [super didReceiveMemoryWarning];    // Dispose of any resources that can be recreated.}@end
