You need to add armv7 and armv6 architectures both to the Architectures and you need to do this as armv6 is architecture supported by devices older than iPhone 3GS and hence if you need to compile or give support to devices prior than iPhone 3GS, you need to add armv6 to your architectures as shown below:

希望这会有所帮助。
