angularjs – 离子视图上的标题[ion-view]

我将我的控制器设置为“chatnow”并使用$stateParams替换$scope.iid作为标题.但聊天消息在单独的变量中更新.我可以使用以下代码更新界面上的消息,但不打印标题.当我删除控制器名称标题被打印而不是消息.帮助我摆脱我的错误.？

App.js：

.state('chatnow',{
  url: '/chatnow/:jid',templateUrl: 'templates/chatnow.html',controller: 'ChatNow'
});

Controller.js

.controller('ChatUserClick',function($rootScope,$scope,$stateParams,$ionicPopup,$state,SendMessage,SharedProperties,ChatMessageService,Profile)   {
  $scope.iid = $stateParams.jid;
  $scope.userJid = $stateParams.jid;
  var sharedData = SharedProperties.sharedObject;
  var MC = this;
  MC.list = ChatMessageService.getList($scope.curchatjid);
})

Chat.html

<ion-view title="{{MC.iid}}" ng-controller="ChatNow as MC">
  <ion-content class="chat">
    <ion-list>
      <li class="item chat-msg-wrap" ng-class="{'msg-send': todo.dt == 'send'}" ng-repeat="todo in MC.list track by $index">
        <div class="chat-msg">{{todo.msg}}</div>
      </li>
    </ion-list>
  </ion-content>
</ion-view>

.state('chatnow',controller: 'ChatNow as MC'
});
