The message is done, but it will be too eye flush, I will use fade in and fade out to implement it
The Text slide animation is done.
I will move and attack the issue of the progressBar.
The plan is that, I will have 2 board, one board use the fool prove way, that is clean the board and fast forward for current position.
Let's compare the difference.
The flexible region is half done, whats the issue right now?
1. I need the animation, but the animation not flexible.
   Can I make it flexible?
   I can, as long as the background image is not the issue, then I am in good shape.
   How to do this?
   Some idea generated, 1. I will create 3 image, they are header, tail and body, the body can be stretched.
So, I could extend without trouble.
   So? In the UIView, I will have a header and tail and body. Then I could stretch it.
Cool, let's take a work then back again
End of an experiment.
I found a better way to build my comment region.
The flexible drop down comment region is done.
The next step is to move it to the common page.
