Make a Simple Program With Xcode

Ever wondered how everyone makes those great programs? Read on to find out how...

Steps

Open Xcode. You may not have Xcode on your system, in that case, install it with the developer tools CD that should have come with your computer.
Click File>new project.
An assistant should open. click "Applescript Application".
Name your project. In this example, it is named "Talking Example".
- Your project should appear.
Double click "Talking_ExampleAppDelegate.applescript".
Type:
- on clicked the object
- (say "hello")
- end clicked
Then type Command+"B" to build.
Now double click "MainMenu.xib".
- Interface builder should open.
  - A window should appear.
Drag a button from the palette, double-click it, and name it "Hello".
Now, open the attribute editor by going to "tools" on the menu bar, and clicking the "attribute editor". Then, at the top of the attribute editor, you should see a little white scroll. Click it.
- QUICK CHECK does your screen look like this?
See the dropdown menu that says "script"? (blue circle) choose "talking example.applescript". Now, see the checkbox that says "action", and under it "clicked"? (red circle) check "clicked". This will make it so that when you click the button, talking example.applescript will activate, thus making it say "hello".
Now click file > save. You may now quit interface builder.
In Xcode, press build and go at the top. Your application should run smoothly.

Beginning with Snow Leopard, Apple has deprecated the use of Applescript Studio, but fear not, in spite of a bit of extra typing, things are actually better without it. Go ahead and grab Xcode 3.2.5 or later. You can get 4.0 in the Mac App Store for free.
File>New Project
Click Applescript Application
Name your project, this example is named "Talking Example"
Your project should appear
Double click "Talking_ExampleAppDelegate.applescript"
There are already some items filled in for you. After the property declaration, insert a new handler:
- on clickedme_(sender)
- say "hello"
- end clickedme_
Type Cmd+B to build
Now double-click MainMenu.xib
Interface builder should open. Close any xib windows it brings up from previous projects you may have worked on.
A blank window should appear and you can drag a button onto it from the Library.
Double click the button and make it "Hello"
CTRL-drag from the Hello button to the blue cube called "Talking Example AppDelegate" and let go. You can now pick the clicked-me event handler to link to the "Hello" button you just made.
Now click file > save. You many now quit interface builder.
In Xcode, press build and go at the top. Your application should run smoothly.
