Ionic: 在iOS模拟器上得到空白的侧边菜单？

Question

我在iOS模拟器上得到一个空白的侧边菜单屏幕，虽然选项是可以点击的。这个问题在浏览器或安卓手机上运行应用程序时不会发生。我使用的是最新的ionic和Xcode。请让我知道如何解决这个问题。先谢谢你。我已经添加了type="overlay "和ION-split-pane，但没有任何效果。

**app.component.html**

<ion-app>
  <ion-menu side="start" menuId="lamb-menu" contentId="lamb-side-menu">
    <app-side-menu></app-side-menu>
  </ion-menu>
  <ion-router-outlet id="lamb-side-menu"></ion-router-outlet>
</ion-app>

**side-menu.component.html**

<ion-content>
  <div class="navbar">
    <a class="nav-open"><span class="icon nav-icon"></span></a>

解决了，是HTML模板的问题。我必须重写HTML和CSS部分，使其在iOS上运行。
