本文解决iOS7应用部署到iPhone5s时遇到的arm64不支持问题。作者通过调整Xcode项目设置，增加arm64架构支持，成功解决了应用程序无法在64位设备上运行的问题。

IOS7 App Development Essentials(4)IPhone5, IPhone5s, IPhone5c

I am using IPhone5 all the time, my test device is an IPhone5c. Recently, I got a new device IPhone5s.

It seems that IPhone5s is 64 bit system, others are 32 bit system. So when I try to deploy and run my app on IPhone5s. I got these problems.

It keeps telling me arm64 is not supported.

So I change my lib and app project as follow
Build Settings —— Architectures

Architectures armv7 armv7s
valid Architectures armv7 armv7s

It works fine after that.

Or we need to add arm64 as follow:

Architectures armv7 armv7s arm64
valid Architectures armv7 armv7s arm64
