xcode4.5

问题 I have made two different background images for my iPhone app: one in 640x960px (iPhone4s) and one in 640x1136px (iPhone5). But when I create the application layouts in the Xcode 4.5 Main Storyboard, how do I define and create it for both iPhone4s and iPhone5? So that the background automatically updates when i choose iPhone5 screen? 回答1: Just import your background image with the correct suffix For example : myImage.png for non-retina display myImage@2x.png for retina display myImage-568h@2x

问题 I'm currently making an iOS App for my school, and have no previous experience with iOS programming. However, I do have experience with HTML/PHP/MySQL. Currently we have a basic tab bar application with 5 tabs at the bottom. Obviously, since this is an app for a school, it needs to be dynamic and hopefully we can set something up to connect to a database and retrieve school lunch menus, and news.
