Still, this is all rather abstract because you haven't seen any real code samples yet, so let's get into some code! For this chapter, you will build an application that someone will use to request some time off from their manager. This is definitely one of those applications that just can't be done without interfacing with other applications on the handheld! To make getting started a little easier we will take the starter TimeOff
application from the code bundle and add to it throughout this chapter.
The first task to undertake is one to help make testing and debugging easier. Remember, you will be working on the simulator, which is essentially a brand new device and which can be often reset. That means you don't have any of your contacts there! You will need some contacts later, so to get started let's add a menu item to the application that will create a few contacts that you can later use to test with.
