iPhone 5 iOS 9.2 编译报错

Undefined symbols for architecture i386:
  "_OBJC_CLASS_$_JPUSHRegisterEntity", referenced from:
      objc-class-ref in XXX.o
  "_kJPFNetworkDidReceiveMessageNotification", referenced from:
      -[XXX registerJPushWithapplication:didFinishLaunchingWithOptions:] in CKJPushManager.o
  "_OBJC_CLASS_$_JPUSHService", referenced from:
      objc-class-ref in XXX.o
      ...
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

原因： 真机和模拟器架构存在本质区别，JPush SDK 不支持 i386 架构（iPhone 5 模拟器为i386架构）

解决方案：切换模拟器为iPhone 5s 或以上设备 如 : iPhone 6
