苹果此前提醒过应用开发者，新应用必须在2015年2月1日后支持64位架构。苹果的 A7和 A8 芯片都是64位处理器。今天，苹果向开发者发送的新邮件中再次提醒到，对于目前应用的升级补丁来说，也必须在6月1日后全面支持64位架构。在6月1日后，递交的任何32位应用都会被苹果拒绝。让应用支持64位并不简单，当然也并不是非常复杂。

 

 

 

Dear Developer,

 

As we announced in October, beginning February 1, 2015 new iOS apps submitted to the App Store must include 64-bit support and be built with the iOS 8 SDK. Beginning June 1, 2015 app updates will also need to follow the same requirements. 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.
