如何使应用程序中的 iPhone 3GS 图标成为 iPhone-4 savvy
我有一个非常简单的问题，关于 iPhone 3/3GS 和 iPhone 4 之间屏幕尺寸的差异。我用谷歌搜索过，但无法找到一个很好的解释。
事情是这样的：标签栏图标。我所有的图标都是 30x30 和 60x60。我将高分辨率的命名为 [icon]@2x.png。当我在自己的 iPhone 3GS 上加载应用程序时，一切都很顺利。但是，当我在模拟器中加载应用程序并模拟具有视网膜显示屏的 4 时，图标看起来像素化，并且显然是错误的分辨率。
我做错了什么？这些是我遵循的确切步骤，但我可能遗漏了一些东西。我需要在 plist 中设置类似选项之类的东西吗？
非常感谢任何帮助！
亲切的问候，
雷德尔
I have a quite simple question concerning the difference in screen size between the iPhone 3/3GS and the iPhone 4. I've googled around, but was unable to come up with a good explanation.
Here's the thing: tabbar icons. All my icons are 30x30 and 60x60. I named the high resolution ones like [icon]@2x.png. When I load my app on my own iPhone 3GS, all goes fine. But when I load the app in Simulator, simulating a 4 with retina-display, the icon looks pixelated and is clearly the wrong resolution.
What am I doing wrong? These were the exact steps I followed, but I'm probably missing something. Is there something like an option I need to set in the plist?
Any help is greatly appreciated!
Kind regards,
Reinder

您需要根据需要命名图标并编辑 plist 文件

确保清理和构建并从手机和模拟器中删除现有应用程序以查看结果

You need to name the icons as you have and edit your plist file

Make sure you clean and build and remove the existing application from your phone and the simulator to see the results
The complete set of icon sizes distilled is

iTunesArtwork – Icon for iTunes AdHoc distribution (512×512)
看来你的做法是正确的。您是否尝试从模拟器中删除该应用程序？清理项目？重新导入图标图像文件？
It seems that you're doing it the right way. Did you try to remove the app from the simulator? Clean up the project? Re-import the icon image files?
尝试（在模拟器停止的情况下）清理所有目标并重新构建。有时 xcode 对它所拥有的文件感到困惑，需要被告知清除其缓存的构建并重新开始。它位于“构建”菜单或 ctrl-shift-K 中。
Try (with the simulator stopped) cleaning all targets and re-building. Sometimes xcode gets dumb about what files it's got and needs to be told to clear its cached build and start fresh. It's in the "build" menu, or ctrl-shift-K.
