Usage

For WKWebView

 HWWebViewJavaScriptBridge *bridge = [[HWWebViewJavaScriptBridge alloc] initWithWebView:self.webView];
    self.bridge = bridge;
    [bridge registerHandler:@"invoke" handler:^(id  _Nonnull data, HWJBResponseCallback  _Nonnull responseCallback) {
        NSDictionary *clientData = @{
            @"code":@(0),
            @"msg":@"success",
            @"data":@{@"company":@"Fooman"}
        };
        responseCallback(clientData);
    }];

 [self.bridge callHandler:@"dispatchEvent" data:@{@"func": @"preRender"} responseCallback:^(id  _Nonnull responseData) {
        NSLog(@"[preRender] callback =%@", responseData);
    }];

For JSContext

    JSVirtualMachine *vm = [[JSVirtualMachine alloc] init];
    JSContext *ctx = [[JSContext alloc] initWithVirtualMachine:vm];
    self.ctx  = ctx;
    HWJSContextJavaScriptBridge *bridge = [[HWJSContextJavaScriptBridge alloc] initWithJSContext:ctx];
    self.bridge = bridge;
    
    // 监听JS调用的postMessage方法
    [bridge registerHandler:@"invoke" handler:^(id  _Nonnull data, HWJBResponseCallback  _Nonnull responseCallback) {
        NSDictionary *clientData = @{
            @"code":@(0),
            @"msg":@"success",
            @"data":@{@"company":@"Fooman"}
        };
        responseCallback(clientData);
    }];

 // 客户端主动调用JS，并得到JS的回应
    NSDictionary *data = @{
        @"func":@"preRender",
        @"params":@{
            @"url":@"https://m.film.qq.com"
        }
    };
    [self.bridge callHandler:@"dispatchEvent" data:data responseCallback:^(id responseData) {
        NSLog(@"[preRender] recieve callback data=%@", responseData);
    }];
