如何为通用iPhone / iPad应用程序指定两个图标？
我希望创建一个支持iPhone和iPad的应用程序。该应用程序可根据需要在两个设备的模拟器中工作。现在我正在尝试构建和部署它。我将plist中的Icon File设置为57x57 .png图像，当我构建并尝试提交应用程序时，ItunesConnect抱怨需要为iPad安装72x72 .png图像。如果我为72x72 .png ItunesConnect指定图标文件，则会抱怨iPhone需要57x57图像。如何在单个plist中指定两个图标？
I hope to create a single app that supports both the iPhone and the iPad. The app works in the simulator for both devices as desired. Now I'm trying to build and deploy it. I set the "Icon File" in the plist to the 57x57 .png image and when I build and try to submit the app ItunesConnect complains about needing a 72x72 .png image for the iPad. If I specify the "Icon File" to the 72x72 .png ItunesConnect complains about needing a 57x57 image for the iPhone. How do I specify both icons in a single plist?
添加 CFBundleIconFiles 类型为Array的键到Info.plist。该数组应包含2个字符串项：两个图标的文件名。然后，操作系统将根据像素尺寸自动为每个平台选择正确的图标。
Add a CFBundleIconFiles key of type Array to your Info.plist. The array should contain 2 string items: the filenames of the two icons. The OS will then automatically choose the correct icon for each platform based on their pixel dimensions.
您可以保留 CFBundleIconFile 键，并指向iPhone 3.0 / 3.1兼容性的图标文件。
You can keep the CFBundleIconFile key and have it point to the icon file for the iPhone for 3.0/3.1 compatibility.
