In this article, I will take the classic "multi-thread Ticket System" in most Java tutorials as an example to implement the same in the iphone.
The following is the java version of t

learning about some common layout methods of the iPhone, we can start to write a page that can really run on the iPhone. In a whisper, I said that I had to finish layout discussion and enter interactive logic development. Later I thought that I could not do it.
