我正在尝试使用适用于 iOS 开发工具包的亚马逊 AWS,但我Apple Mach-O Linker errors在 Xcode 5.0.1 中不断获得几个
Undefined symbols for architecture armv7:
  "_OBJC_CLASS_$_S3CreateBucketRequest", referenced from:
      objc-class-ref in CreationViewController.o
  "_OBJC_CLASS_$_S3Region", referenced from:
      objc-class-ref in CreationViewController.o
  "_OBJC_CLASS_$_AmazonEndpoints", referenced from:
      objc-class-ref in CreationViewController.o
  "_OBJC_CLASS_$_AmazonS3Client", referenced from:
      objc-class-ref in CreationViewController.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
我进入了构建阶段并确保AWSES.framework包含在link binary with libraries. 在编译源中还包括 CreationViewController.m。Target Memberships 似乎也是正确的。我还可以做些什么?
