Converting iPhone xib to iPad xib?

I was able to narrow it down to a few things, so here are the steps that worked for me:

1) Make a copy of the iPhone xib file and add it to your project

2) Right click the file (in xcode) and Open As > Source Code

3) The 2nd line should look like:

<archive type="com.apple.InterfaceBuilder3.CocoaTouch.XIB" version="7.10">

Replace with:

<archive type="com.apple.InterfaceBuilder3.CocoaTouch.iPad.XIB" version="7.10">

4) Search for "IBCocoaTouchFramework" and Replace all occurrences with "IBIPadFramework"

5) Save the file and Open As > Interface Builder - iOS

The file might still look like a regular iPhone xib, but for me, once I changed the Status Bar to "Black" in the Attributes inspector the rest of the xib just kind of "snapped" into an iPad xib

In Xcode 5 you should just:

Find:

<document type="com.apple.InterfaceBuilder3.CocoaTouch.XIB" version="3.0" toolsVersion="4510" systemVersion="12F37" targetRuntime="iOS.CocoaTouch" propertyAccessControl="none">

Replace by:

<document type="com.apple.InterfaceBuilder3.CocoaTouch.iPad.XIB" version="3.0" toolsVersion="4510" systemVersion="12F37" targetRuntime="iOS.CocoaTouch.iPad" propertyAccessControl="none">

Note we are just adding .iPad to the type and targetRuntime properties.

After opening just select a new Size to adjust. Example: iPad Full Screen.

Assume you've the SDK with Xcode 3,

1. Open IB.
2. Open the XIB.
3. File -> Create iPad version using autoresizing masks.
