windows-phone - Windows phone：在列表视图中加载数据非常慢（Appcelerator Titanium）

Question

我的 Windows Phone 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，我收到一条超时消息。

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，但在我看来还是有点长.

我不知道是什么导致了这种延迟。任何建议都非常感谢。

这是在列表视图中加载数据的代码。（钛 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'}},
