Hi, I'm new to xcode 4, I use my current project file xcode 3.1.3 and I open it in xcode 4 and run. My MainWindow.xib in Interface Builder is still iphone size, whereas I adjusted my other view in ipad size (1024 x 768). In my BUILD SETTINGS for my PROJECT and TARGET, I set the "Targeted Device Family" to iphone/ipad. When I run the ipad simulator, it looks good and fit into the ipad screen. But when I run it in iphone simulator, the screen doesn't fit in and also has been cropped by iphone view. I thought if you made the ipad size, and if you transfer to iphone, it will auto adjust? Or maybe I miss something in settings? Hope anyone could help me here. Thanks.
