问题
I'm making a universal app based on the Utility App template. I've selected a universal app and the MainView.xib and MainView~iPad.xib work properly on both device types.
On the iPad2, when I switch to the FlipsideView, it loads FlipsideView.xib even though there is a perfectly good FlipsideView~iPad.xib file in the project. The default xib is normal (iPhone) sized and displaying in the lower left hand corner of the iPad.
I did have to create the FlipsideView~iPad xib manually. I believe I have the xib properly wired in IB as it shows identical to the FlipsideView.xib connections.
Over the last couple weeks, I've read quite a few posts with similar problems and this Stack Overflow thread answers most clearly and contains links to Apple documentation. So I know it works for others and is documented.
The code for this section is identical to the showInfo() method in the stock Utility App template.
(Yes I realize I can manually load the ~iPad version checking UI_USER_INTERFACE_IDIOM(). I'm trying to figure out what I'm doing wrong in getting the ~iPad modifier to work.)
Any ideas what I'm missing?
Thanks a ton for your help!
回答1:
in the end i found the solution. it is really very very simple. The xib must be named ~ipad instead of ~iPad, and ~iphone instead of ~iPhone. The bad thing is the if you name them ~iPad, everything works in the simulator but it does not work on the real device.

It can be done automatically based on the name, no worries. The only problem is you'll need to switch your naming convention. MainView.xib will be your iPad xib and MainView~iphone.xib will be your iPhone xib. Then it should work perfectly for you and you don't have to do anything but alloc/init.
