从iTunes出错无效二进制连接？

我有我的提交者普遍应用.app文件到iTunes连接，它显示无效的二进制文件的地位，我得到了来自苹果的邮件。邮件内容是

I have submitter my universal application .app file to iTunes connect and it shows 'Invalid Binary' status and i got a mail from apple. The mail content is

"Invalid Binary Architecture - iOS 3.0 introduced support for multiple binary architectures. If your binary is built for multiple architectures, your Info.plist must have a MinimumOSVersion key with a value of at least 3.0. Additionally, if your app is intended to support earlier iPhone and iPod touch models, your app must contain at least an armv6 binary; "thin" armv7-only binaries will not be accepted unless the armv7 required device capability is also present in the Info.plist UIRequiredDeviceCapabilities key or the MinimumOSVersion key has a value of 4.3 or higher.". 

这是我第一次在提交应用程序商店。如何帮我解决这个问题？我能做到这一点？我不明白邮件内容的实际意义。请帮帮我。
