Objective-C JSON模型

Question

我按照說明將JSONModel安裝到我的項目中。 但是，我遇到了Apple Mach問題-O鏈接器錯誤。

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_NSEntityDescription", referenced from:
      objc-class-ref in JSONModel+CoreData.o
  "_OBJC_CLASS_$_NSManagedObject", referenced from:
      l_OBJC_$_CATEGORY_NSManagedObject_$_JSONModel in JSONModel+CoreData.o
      objc-class-ref in JSONModel+CoreData.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我還添加了SystemConfiguration.framework。

請幫我。 謝謝。

將CoreData.framework添加到您的目標。
