//注册jscalloc⽅法，js调⽤oc,data为oc回调给js的参数

------------------------------------------------------------------
//OC端的调⽤
//调⽤js中注册的showapiinner⽅法，不传⼊数据，没有回调
//[_bridge callHandler:@"showapiinner"];
//调⽤js中注册的showapiinner⽅法，传⼊数据str，没有回调
//[_bridge callHandler:@"showapiinner" data:str];
原生js和js的区别//调⽤js中注册的showapiinner⽅法，传⼊数据str，且有回调（可以获取到回调参数responData）
// [_bridge callHandler:@"showapiinner" data:str responseCallback:^(id //responseData) {
// NSLog(@"%@",responseData);
// }];
[self renderButtons:self.wkWebView];
[self loadExamplePage:self.wkWebView];
}
//native调js  （native按钮）
