在一个视图上的离子隐藏页脚

Question

我试图只在我的一个离子视图中隐藏页脚，无论我尝试什么，我似乎无法让它工作。有任何想法吗？我尝试过使用ng-hide但没有用。我似乎无法解决问题所在。我将附加视图的代码以及调用页脚的索引。

Launchpad.html

<ion-view hide-nav-bar="true">

  <ion-content class="padding uaContent">
    <search-results></search-results>

    <div ng-hide="query">
      <h2 class="card headingCard text-center padding">What do you want to do?</h2>
      <br>
      <ion-grid>
        <ion-row>
          <ion-col>
            <a ng-click="navToPlaylist()">
              <img src="img/myfavorites.png" width="65.6%" height="100%">
            </a>
          </ion-col>
          <ion-col>
            <a ng-click="navToSchedule()">
              <img src="img/program.png" width="32.8%" height="100%">
            </a>
          </ion-col>
        </ion-row>
        <ion-row>
          <ion-col>
            <a href="#/menu/guide">
              <img src="img/interactive.png" width="65.6%" height="100%">
            </a>
          </ion-col>
          <ion-col>
            <a ng-click="navToExhibitors()">
              <img src="img/exhibitors.png" width="32.8%" height="100%">
            </a>
          </ion-col>
        </ion-row>
        <ion-row>
          <ion-col>
            <a href="#/menu/smart">

        </ion-row>
        <ion-row>

            <a ng-click="navToInfo()">
