我刚刚创建了一个精心生成的图标网格（imageViews），现在我需要能够对它们做一些事情。但是，我发现我试图绑定的事件侦听器没有被绑定。窗口加载，我的图标显示得很好，但它们不可点击。
谁能看到我错过了什么？下面的代码是一个功能齐全的（除了不起作用的部分）文件。您应该能够将其复制到测试应用程序中并立即加载（目前可能仅限 iPhone）。
任何见解将不胜感激。
// this sets the background color of the master UIView (when there are no windows/tab groups on it)
Ti.UI.setBackgroundColor('#000');

backgroundColor:'#fff',
layout: 'vertical',
navBarHidden: true,
});
// icon grid
