iPhone icon size
提问by Zaid Amir
I am developing an application for iPhone to support multiple devices, iPhone 2-4. I had an issue with the app icon as it was shown pixelated in the iPhone 4 simulatorso I have used a new image with higher resolution (300 x 300) to be precise. On the simulator its showing fine for both iPhone 4 and the iPhone device simulators. However, when I ported my app to an iPhone 3 actual device the icon did not show at all and instead I get a blank white icon. I don't have an iPhone 4 yet so I cant tell if the same issue will happen on the physical device.
我正在为 iPhone 开发一个应用程序来支持多种设备，iPhone 2-4。我遇到了应用程序图标的问题，因为它在 iPhone 4模拟器中显示为像素化，所以我使用了更高分辨率 (300 x 300) 的新图像来精确。在模拟器上，它对 iPhone 4 和 iPhone 设备模拟器都显示良好。但是，当我将我的应用程序移植到 iPhone 3 实际设备时，该图标根本没有显示，而是一个空白的白色图标。我还没有 iPhone 4，所以我不知道在物理设备上是否会发生同样的问题。
I am not sure what is the best dimensions/dpi to use for an icon to display perfectly on an iPhone 4 and older devices? Would appreciate a help if possible..
我不确定在 iPhone 4 和旧设备上完美显示图标的最佳尺寸/dpi 是多少？如果可能的话，将不胜感激。

For older devices, save your 57x57icon as Icon.png. For the iPhone 4, save your 114x114icon as [email protected]. The image resolution doesn't matter at all; only the pixel dimensions matter.
对于较旧的设备，请将57x57图标另存为Icon.png. 对于 iPhone 4，将114x114图标另存为[email protected]. 图像分辨率根本不重要；只有像素尺寸很重要。
There are other sizes to cater to, like Spotlight/Settings icons and iPad icons. There's a full list written up in the library documentation.
还有其他尺寸可以满足，例如 Spotlight/设置图标和 iPad 图标。库文档中有完整的列表。

I have not seen the pixelated issue on the iOS4 simulator like you did using an app that was originally written for iOS3+ with a standard 57x57 icon.
我还没有在 iOS4 模拟器上看到像素化问题，就像您使用最初为 iOS3+ 编写的带有标准 57x57 图标的应用程序一样。

Ive put all the images named correctly at the correct size into a github repo, so there can be no confusion.
我已将所有以正确大小正确命名的图像放入 github 存储库中，因此不会出现混淆。

Make sure that "Icon.png" and "[email protected]" are capitalized or else the application archive will not pass the validation process.
确保“Icon.png”和“[email protected]”大写，否则应用程序存档将无法通过验证过程。

You can set the various icon image names in the plist, under "icon files".
您可以在 plist 中的“图标文件”下设置各种图标图像名称。
