navigationbar - Steroids: NavigationBarButton displayed then vanished

Question

I'm new to Steroids and I'm trying to display a modal view with a button in the native navigation bar (will use it later for a side drawer).

Note: The use of a modal view doesn't require to override potential existing back button on the left side.

My view and its content are displayed normally with a nice NavigationBarButton "Filtres". But once the view is fully loaded the navigation bar is reloaded and the navigation bar button disappears.

Any idea why this happens and how fix it?

Here is the controller code:

    angular
      .module('profile-list')
      .controller('IndexController', function($scope, supersonic) {

        var drawerButton = new supersonic.ui.NavigationBarButton({    
            title: "Filtres",
            onTap: function(){    
                supersonic.logger.debug("click");
            }    
        });

        var navigationBarOptions = {    
            buttons: {
                left: [drawerButton]
            }    
        };

        supersonic.ui.navigationBar.update(navigationBarOptions);

});

Thanks

尝试像这样包装导航栏更新：

supersonic.ui.views.current.whenVisible( function(){
    var drawerButton = new supersonic.ui.NavigationBarButton({    
        title: "Filtres",
        onTap: function(){    
            supersonic.logger.debug("click");
        }    
    });

    var navigationBarOptions = {    
        buttons: {
            left: [drawerButton]
        }    
    };

    supersonic.ui.navigationBar.update(navigationBarOptions);
});

此外，您可以测试右侧的按钮，以防overrideBackButton它以某种方式将自身设置为 true。
