Mac x os系统用xcode下编写iphone手机程序的经典hello入门代码

### HelloWorld ###

================================================================================
DESCRIPTION:

HelloWorld is a sample application that demonstrates the use of a button, a text field to enter text into using a keyboard, and a text label to display text. The button and the main view both have background images.  

HelloWorld presents a simple interface. If you don't enter anything in the text field and touch the Hello button, the label displays "Hello World!". If you enter your name in the text field, the label displays "Hello <name>!" when you touch the Hello button.

The application is discussed in more detail in "Your First iPhone Application" in the Reference Library <http://developer.apple.com/iphone/library/documentation/iPhone/Conceptual/iPhone101/>.
