推荐答案

图标应为57x57像素的PNG。 Apple生成的PNG的PPI为72.01，所以我想这个范围内的东西都能正常工作。没有非常高的PPI，否则图像不能正确呈现。

The icon should be a 57x57 pixel PNG. The PNGs generated by Apple have a PPI of 72.01 so I guess something in that range will work fine. Don't have a very high PPI else images are not rendered properly.

如果您想使用自定义图标而不让iPhone将光泽应用于您的图标，请在info.plist中添加一个名为UIPrerenderedIcon的键（是一个布尔值）并将其检查。

If you want to use a custom icon and not let the iPhone to apply the gloss to your icon, add a key to info.plist called UIPrerenderedIcon (is a boolean value) and make it checked.

将应用程序提交到应用程序商店时，您需要一个512x512像素版本的应用程序图标（这个版本为jpeg或tiff格式）以及至少一个应用的屏幕截图。您可以额外获得该应用的4个屏幕截图。

When submitting the app to the app store, you will need a 512x512 pixel version of your app's icon (this one in jpeg or tiff format) and at least one screenshot of your app. You can have additional 4 screenshots of the app.

现在图标的规格（将在iTunes中提交）并且应用程序图标已更改。要提交给itunesconnect的图标必须是1024x1024像素。

EDIT Now the specs for icon (to be submitted in iTunes connect) and the app icons have changed. The icon to be submitted to itunesconnect must be 1024x1024 px.

对于应用程序图标，您可以在此处找到详细信息 - http：// developer.apple.com/library/ios/#documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/App-RelatedResources/App-RelatedResources.html#//apple_ref/doc/uid/TP40007072-CH6-SW1

For the app icons, you can find details here - http://developer.apple.com/library/ios/#documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/App-RelatedResources/App-RelatedResources.html#//apple_ref/doc/uid/TP40007072-CH6-SW1

另外，请确保图标文件是非交错的PNG文件。最近我们的一个应用程序的二进制文件被标记为无效，因为其中一个应用程序图标文件是隔行扫描的PNG。

Also, make sure the icon files are NON-INTERLACED PNG files. Recently one of our apps' binary was marked invalid since one of the app icon files was an interlaced PNG.
