关于适配iphone5，Invalid Launch Image的退信
本人xcode 4.3，所开发客户端新版本准备提交，应用中做了关于iphone5的适配，然后打包提交。
在提交审核的时候被拒，收到苹果的邮件：
Invalid Launch Image
Your app contains a launch image with a size modifier that is only supported for apps built with the iOS 6.0 SDK or later.
然后就网上去找答案，网上找到说要支持到ios4.3以后，ios deployment taeget 改为4.3尝试打包提交，结果还是被拒了。
那是一个郁闷，于是去查文档。
然后文档就有说：
Invalid Launch Image
An example of this rejection email follows:
Your app contains a launch image with a size modifier that is only supported for apps built with the iOS 6.0 SDK or later.
This issue results from building your application with iOS SDK 5.1 and earlier and adding a Default-568h@2x.png image to it in order to support the 4-inch retina display. If you intend to support the 4-inch retina display, then you must build your application against the iOS 6.0 SDK. If you do not intend to build your application against iOS 6 SDK, then remove Default-568h@2x.png from your project.
Note: iOS SDK 6.0 is only supported by Xcode 4.5 and later.
文档的意思也就是说如果你想添加 Default-568h@2x.png 图片（支持iphone5），就需要用ios6.0的sdk打包。要不然你就删了Default-568h@2x.png。
下面是文档连接：http://developer.apple.com/library/ios/#technotes/tn2294/_index.html#//apple_ref/doc/uid/DTS40011374
xcode4.3不支持，4.5以后才可以。
于是整个xcode 4.5打包，最后顺利提交。期间也不甘心应用只支持ios4.3以后，虽然找过一些资料说可以打包或者有人说通过了审核，但我们的应用没能解决问题，最后还是无奈了。
