如何将xib文件再ipad和iphone之间互相转换

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
