加速器。刷新表格时选项对话框多次打开
钛金SDK版本：1.7.0.RC1 iPhone SDK 版本：4.2
我正在 Appcelerator 中开发 iOS 应用程序。我正在从 Twitter 检索推文并将其插入表中。对于每一行/推文，我还提取该单个推文/行的包含链接，用户可以从单击该行时打开的选项对话框中选择它们。
问题是，如果我重新加载页面并单击该行，则会打开两个对话框。如果我单击三次，则会打开三个对话框，依此类推。如何确保该对话框仅打开一次？
这是我的代码： http://pastie.org/2004091
感谢所有帮助！
Titanium SDK version: 1.7.0.RC1

I am developing an iOS app in Appcelerator. I am retrieving tweets from twitter and inserting them into a table. For each row/tweet I am also extracting the containing links for that individual tweet/row and the user can select them from an options dialog which is opened when the row is clicked.
The problem is that if I reload the page and click the row, two dialogs are open upon each other. If I click three times, three dialogs is opened and so on. How can I make sure that the dialog only opens once?

Thankful for all help!

我有类似的问题。尤其是在 iPhone 3G 上，因为运行速度很慢，而且您更容易多次点击某些内容。我解决这个问题的方法是从事件监听器本身中删除事件监听器。或者您设置一个变量并在事件侦听器中测试其值。因此，如果您将变量调用“clicked”设置为 false。当侦听器第一次检查 'clicked' = false 时，如果将其设置为 true，则下次不会执行代码。
I had a similar problem. Especially on the iPhone 3G as this runs slowly and you're more tempted to tap things more than once. The way I got around it is to either remove the event listener from within the event listener itself. Or you set a variable and test for its value in the event listener. So, if you set a variable call 'clicked' to false. When the listener is first check for 'clicked' = false, if it is set it to true so next time the code is not executed.
