如何在xcode 6中构建32位和64位的单二进制文件

我已经遵循 this堆栈溢出解决方案,但即使我得到低于警告.

Missing 64 bit support.Starting February 1,2015,new iOS apps uploaded to the App Store
must include 64-bit support and be built with the iOS 8 SDK,included in Xcode 6 or later.
To enable 64-bit in your project,we recommend using the default Xcode build setting of 
“Standard architectures” to build a single binary with both 32-bit and 64-bit code.

我已经选择

Project - Target - Build settings - Architectures - Standard Architectures(armv7,arm64).

虽然我得到了警告.请帮帮我.谢谢.

解决方法

有同样的问题.看起来将’arm64’添加到Valid Architectures(也在构建设置下)解决了它.
