build 报错：
Undefined symbols for architecture i386:
"OBJC_CLASS$_CMMotionManager", referenced from:
objc-class-ref in AlipaySDK
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
打开xcode看link binary with libraries 已经引入了AlipaySDK库，但是开始报以上错误？
