### HelloWorld ### |

================================================================================ |
DESCRIPTION: |
|
HelloWorld is a sample application that demonstrates the use of a text field to enter text using a keyboard, and a text label to display text. |
|
HelloWorld presents a simple interface. When the application launches, it displays a navigation bar containing a text field. Tap on the text field to enter your name. Tap the Done button on the keyboard to dismiss the keyboard. The application then displays in a label what you typed in the text field. |
|
The basic features of the application are discussed in more detail in "Your First iPhone Application" in the Reference Library <http://developer.apple.com/iphone/library/documentation/iPhone/Conceptual/iPhone101/>. |
