ToDo App iPhone

All of the iPhone/iTouch applications that currently exist were created without the official SDK. To be brought into the eventual iTunes distribution system, these applications will eventually need to be converted over.

The first one to appear in the wild is Erica Sadun’s ToDo App 0.25. It appears in the Aspen Simulator as Tapp.

To Do lists can be created and edited. Each list can be set as either normal or high priority. Each list can have items added to it. A list can be grayed out by setting it as completed.

It is a super simple app. However, it is first public “hello world” application of the new sdk.

For developers not familiar with Xcode, the iPhone SDK can be a little confusing. Here is the brain dead simple way to get from SDK to a working sample in the iPhone Simulator.

The long painful parts of the process is actually getting access to the SDK, downloading it, and installing it. If you go through the Apple Dev Center, you will need to create an account before you will get the SDK link. You can also get the SDK from multiple torrent sites. Downloading and installing are not difficult but time consuming considering the size of the files involved. Once the files are installed, everything gets easy.

1. Open the Xcode app
2. Select File -> New Project
3. Select the Cocoa Touch Application
4. Select a name and save it in the Documents folder
5. Once the project appears, click Build and Go
6. The Aspen iPhone Simulator will load
7. Close Simulator by clicking the Tasks stop button

Fun, huh?
