问题描述

按build + debug时出现此错误:

I got this error when I press build+debug:

ld: duplicate symbol .objc_class_name_BlogTableItemCell in /Users/fabian/Development/Workspaces/iphone_experiments/xcode_build_output/MausLog.build/Debug-iphonesimulator/MausLog.build/Objects-normal/i386/BlogTableItemCell-3733583914888A7B.o and /Users/fabian/Development/Workspaces/iphone_experiments/xcode_build_output/MausLog.build/Debug-iphonesimulator/MausLog.build/Objects-normal/i386/BlogTableItemCell-3733583914888A7B.o

推荐答案

似乎您正在同一代码的不同位置两次编译同一BlogTableItemCell类.在以下情况下可能会发生这种情况.

It seems that you are compiling the same BlogTableItemCell class two times in different places of your code. This may happen in the following cases.

• 您已经上过同一堂课 实施分为两个不同 档案;

• You have put the same class implementation into two different files;

您实际上只有一个 但是，该类的实现 您还在项目中链接了一个框架 或包含其类的类的库 名称与您的名字完全相同.

You actually have just one implementation of this class, however you are also linking in your project a framework or library containing a class whose name is exactly the same of yours.

尝试在整个项目中查找您的班级，并确保项目中只有一个副本.

Try finding in the whole project your class and make sure only one copy is available within your project.
