Windows手机：在listview中加载数据非常慢（Appcelerator Titanium）

Question

我的Windows手机应用程序有问题。 我尝试在列表视图中加载大约80个项目。当我在控制器中执行此操作并在应用程序启动时创建控制器实例时，我会收到超时消息。

当我在应用程序启动后调用loadData方法时，它可以工作，但是加载数据大约需要27秒（在设备上），在模拟器中大约需要4秒，这要好得多，但仍然有点长在我看来。

我不知道导致这种延迟的原因。任何建议都非常感谢。

这是在listview中加载数据的代码。 （Titanium SDK 5.3.0.GA）

function loadData() {
var fruitSection = Ti.UI.createListSection({ headerTitle: 'Fruits'});
var fruitDataSet = [
    {properties: { title: 'test item'}},
    {properties: { title: 'test item'}},
    {properties: { title: 'test item'}},
    {properties: { title: 'test item'}},
    {properties: { title: 'test item'}},
    {properties: { title: 'test item'}},
    {properties: { title: 'test item'}},
    {properties: { title: 'test item'}},
    {properties: { title: 'test item'}},
    {properties: { title: 'test item'}},
    {properties: { title: 'test item'}},
    {properties: { title: 'test item'}},
    {properties: { title: 'test item'}},
