问题
I want to make a application which can run complete in iPhone and iPad (full mode, not x2 mode). Please help me. Thank in advance!
I found down a config called "Targeted Device Family", but I still don't know what about design (for iPhone, iPad), how to show UI if device is iPhone, how to show UI if device is iPad.

See "Creating a Universal Application" in the iOS Application Programming Guide for details on how to set this up in Xcode, and what pieces you need to provide.
回答2:
Target Device Family: iPad/iPhone. You need then two xib-Files if you want two different designs. One for the iPad Resolution and one for the iPad resolution. Like MainWindow-iPad.xib and MainWindow-iPhone.xib or you implement a recognition of the device in your code.
For more information look into this thread.

You need to create a Universal iOS app :) google "convert iPhone app into universal app". Things get a lot easier when your project is done in interface builder.
