Continue to narrow it down. I ruled out ButtonBase.as, the real problem is TextBase.as and RichEdiableText.as
If you set a custom skin to a Button control, and in your custom skin if you don't use Label, RichText or RichEditableText at all, then you Button can be displayed on iOS devices. If you use Label, RichText or RichEditableText in your Flex application, this issue will happen, the application will hanging on a blank screen forever! The Label and RichText, they all extend from TextBase, the RichEdiableText extends from UIComponent. There must be something in common between TextBase.as and RichEdiableText.as, I'm still digging.
