Manually add Three20 to your project
    원본 주소:http://three20.info/article/2010-10-06-Adding-Three20-To-Your-Project
Locate the "Three20.xcodeproj" file under " three20/src/Three20/ ". Drag Three20.xcodeproj and drop it onto the root of your Xcode project's "Groups and Files" sidebar. A dialog will appear -- make sure "Copy items" is unchecked and "Reference Type" is "Relative to Project" before clicking "Add".
Open the Three20 Xcode Project that you just added to your app and expand the "Dependencies" group. Select all of the projects listed there and drag them to your app as well. You should now have the following list of Three20 projects added to your app:
Three20Core
Three20Network
Three20Style
Three20UICommon
Three20UINavigator
Three20UI
Three20

Link the Three20 static libraries to your project. Select all of the project items that you just added to the sidebar.Under the "Details" table, you will see a number of items, such as libThree20.a and libThree20Core.a. Check the checkbox on the far right for each of the  lib  files (not the UnitTests). This will link each part of the Three20 framework to your app.
Add Three20 as a dependency of your project, so Xcode compiles it whenever you compile your project. Expand the "Targets" section of the sidebar and double-click your application's target. Under the "General" tab you will see a "Direct Dependencies" section. Click the "+" button, select "Three20" and each of the other libs, and click "Add Target". You do not need to add the  UnitTests  target for each lib.
Add the bundle of images and strings to your app. Locate "Three20.bundle" under "three20/src" and drag and drop it into your project. A dialog will appear -- make sure "Create Folder References" is selected, "Copy items" is unchecked, and "Reference Type" is "Relative to Project" before clicking "Add".
Add the Core Animation framework to your project. Right click on the "Frameworks" group in your project (or equivalent) and select Add > Existing Frameworks. Then locate QuartzCore.framework and add it to the project.
Finally, tell your project where to find the Three20 headers. Open your "Project Settings" and go to the "Build" tab. Look for "Header Search Paths" and double-click it. Add the relative path from your project's directory to the "three20/Build/Products/three20" directory.
While you are in Project Settings, go to "Other Linker Flags" under the "Linker" section, and add "-ObjC" to the list of flags. WARNING: Make sure that you do this for all configuration settings, not just the active one.
You're ready to go. Just #import "Three20/Three20.h" anywhere you want to use Three20 classes in your project. It's recommended that you do so in a precompiled header for faster build times.
