一张图概括H5与原生交互

- (void)webView:(WKWebView *)webView runJavaScriptTextInputPanelWithPrompt:(NSString *)prompt
    defaultText:(nullable NSString *)defaultText initiatedByFrame:(WKFrameInfo *)frame
completionHandler:(void (^)(NSString * _Nullable result))completionHandler

runJavaScriptTextInputPanelWithPrompt方法中获取到JS传给原生的方法。

调用JS与原生定义好的方法名和获取到参数

   SEL sel=NSSelectorFromString(methodOne);
        SEL selasyn=NSSelectorFromString(methodTwo);
        NSDictionary * args=[JSBUtil jsonStringToObject:argStr];
        id arg=args[@"data"];
        if(arg==[NSNull null]){
            arg=nil;
        }

定义一个action执行objc_msgsend

 void(*action)(id,SEL,id,id) = (void(*)(id,SEL,id,id))objc_msgSend;
action(JavascriptInterfaceObject,selasyn,arg,completionHandler);

定义一个JsApi

在初始化的时候需要将上述的方法在注册在自定义web view中

 // add internal Javascript Object
    InternalApis *  interalApis= [[InternalApis alloc] init];
    interalApis.webview=self;
    [self addJavascriptObject:interalApis namespace:@"_dsb"];

- (void) addJavascriptObject:(id)object namespace:(NSString *)namespace{
    if(namespace==nil){
        namespace=@"";
    }
    if(object!=NULL){
        [javaScriptNamespaceInterfaces setObject:object forKey:namespace];
    }
}
