当在应用商店上提交应用时，状态为“无效二进制"?

我正在应用商店上提交一个应用，提交成功后，状态为无效二进制.在我从苹果收到的邮件中是:

I am submitting an app on app-store and after successful submit the status is Invalid Binary. And in the mail which I have received from apple is :

iPhone 5优化要求-您的二进制文件未针对 iPhone 5 优化.

iPhone 5 Optimization Requirement - Your binary is not optimized for iPhone 5.

从5月1日起，所有新提交的iPhone应用程序和应用程序更新必须支持 iPhone 5 上的4-inch显示.

As of May 1, all new iPhone apps and app updates submitted must support the 4-inch display on iPhone 5.

所有应用程序都必须在启动图像文件名部分之后紧随其后的启动图像包含-568h大小修饰符.启动映像必须是PNG文件，并且位于包的顶层，或者在每个包中提供.

All apps must include a launch image with the -568h size modifier immediately following the portion of the launch image's filename. Launch images must be PNG files and located at the top-level of your bundle, or provided within each .

lproj文件夹(如果您本地化启动映像).通过查看《 iOS人机界面指南》和《 iOS App编程指南》，了解有关 iPhone 5 支持和应用启动图像的更多信息.

lproj folder if you localize your launch images. Learn more about iPhone 5 support and app launch images by reviewing the iOS Human Interface Guidelines and iOS App Programming Guide.

所以请告诉我该怎么做.我已在关键启动图像的app.plist中设置了Default.png.现在，必须在其中设置 iPhone 5 的启动图像以及使用哪个键.

so please tell me what to do for it. I have set the Default.png in the app.plist in key Launch image. Now where I have to be set launch image for iPhone 5 and with which key.
