Titanium UI DashboardView删除项目？

Question

有没有办法从现有的Titanium.UI.DashboardView添加或删除DashboardItem？

不幸的是，没有简单的方法来删除一个项目。您必须删除当前的仪表板视图并重新创建它，

var win = Ti.UI.createWindow({ 
    backgroundColor: '#13386c' 
}); 

var button = Ti.UI.createButton({ 
    title: 'Change Items', 
    top:10 
}); 
win.add(button); 

var dashboardData = []; 
var itemData = [ 
    { name: 'account', badge: 1 }, 
    { name: 'cases', badge: 2 }, 
    { name: 'calls', badge: 3 }, 
    { name: 'contacts', badge: 4 }, 
    { name: 'emps', badge: 5 }, 
    { name: 'leads', badge: 6 }, 
    { name: 'meetings', badge: 7 }, 
    { name: 'opps', badge: 8 } 
]; 

for (var i = 0; i < itemData.length; i++) 
{ 
    var item = Ti.UI.createDashboardItem({ 
     badge: itemData[i].badge, 
     image:'/path/to/an/image.png', 
     label: itemData[i].name 
    }); 
    dashboardData.push(item); 
} 

var dashboard = Ti.UI.createDashboardView({ 
    data: dashboardData, 
    top:100 
}); 
win.add(dashboard); 

button.addEventListener('click', function(e) 
{ 
    dashboardData = []; 
    win.remove(dashboard); 
    dashboard = null; 
    dashboard = Ti.UI.createDashboardView({ 
     top:100 
    }); 
    win.add(dashboard); 

    var newItemData = [ 
     { name: 'account', badge: 1 }, 
     { name: 'calls', badge: 3 }, 
     { name: 'emps', badge: 5 }, 
     { name: 'meetings', badge: 7 } 
    ]; 

    for (var i = 0; i < newItemData.length; i++) 
    { 
     var item = Ti.UI.createDashboardItem({ 
      badge: newItemData[i].badge, 
      image:'/path/to/an/image.png', 
      label: newItemData[i].name 
     }); 
     dashboardData.push(item); 
    } 
    dashboard.data = dashboardData; 
}); 
win.open(); 

我把这个例子一起鞭打了一下。我相信它可以变得更高效
