如何强制 Ionic 在特定页面上显示后退按钮?

How can I force Ionic to display back button on certain page?

Javascript:

Javascript:

.state('app.tab.playlists', { //<!-- Tab content page
  url: '/playlists',
  views: {
    'tab-Content': {
      templateUrl: 'templates/playlists.html',
      controller: 'PlaylistsCtrl'
    }
  }
})

.state('app.singer', { //<!-- Not tab content page (if you navigate from tab page to this page, back button will not displayed)
  url: '/singer',
  views: {
    'menuContent': {
      templateUrl: 'templates/singer.html'
    }
  }
})

推荐答案

你可以在你的控制器中告诉它.试试:

You can tell it in your controller. Try:

 .controller('yourCtrl', function($scope) {

$scope.$on('$ionicView.beforeEnter', function (event, viewData) {
  viewData.enableBack = true;
}); 

})

但就像 LeftyX 说的那样.选项卡到非选项卡视图的历史记录功能有问题.

But like LeftyX said. The history function for tab to non tab view is buggy.
