For the More Curious: The Application Bundle
When you build an iOS application project in
Xcode
, you create an
application bundle
. The
application bundle contains the application executable and any resources you have bundled
with your application. Resources are things like XIB files, images, audio files - any files
that will be used at runtime. When you add a resource file to a project,
Xcode
is smart
enough to realize that it should be bundled with your application and categorizes it accord-
ingly.
How can you tell which files are being bundled with your application? Select the
Homep-
wner
project from the project navigator. Check out the
Build Phases
pane in the
Homepwn-
er
target. Everything under
Copy Bundle Resources
will be added to the application bundle
when it is built.
Each item in the
Homepwner
target group is one of the phases that occurs when you build a
project. The
Copy Bundle Resources
phase is where all of the resources in your project get
copied into the application bundle.
You can check out what an application bundle looks like on the filesystem after you install
an application on the simulator. Navigate to
~/Library/Application Support/
iPhone Simulator/(version number)/Applications
. The directories with-
in this directory are the application sandboxes for applications installed on your computer's
iOS simulator. Opening one of these directories will show you what you expect in an ap-
plication sandbox: an application bundle and the
Documents
,
tmp
, and
Library
direct-
ories. Right or Command-click the application bundle and choose
Show Package Contents
from the contextual menu.
