iOS手动集成推送sdk，无法运行的错误

按照文档进行的开发，一直报这个错误

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

请问该如何解决，谢谢
