编译时zxing的ChecksumException.h 中
````
#ifndef __CHECKSUM_EXCEPTION_H__
#define __NOT_FOUND_EXCEPTION_H__
````
'__CHECKSUM_EXCEPTION_H__' is used as a header guard here, followed by #define of a different macro
我把#define 里改成__CHECKSUM_EXCEPTION_H__ 后又在zxing其他地方有编译错误了。
在Xcode 5.0.2 中确实没有问题的，我想是不是5.1的编译器参数有不一样了吗？

我改了一下...其他地方都是 unused 错误...用 宏 标记一下 就好了 http://stackoverflow.com/questions/18423449/ignore-unused-entity-issue-unused-variable-in-a-single-file
应该可以修改编译选项 关闭掉... |

在工程ZXingWidget中的 build settings
在 Apple LLVM 5.1 - Custom Compiler Flags项目中 将Other Warning Flags的所有项目给删除掉。 然后 重新编译就可以了 |

6楼正解哦！
这样删除不知道，有什么后遗症吗？ |

Looks like there are some underground compiler settings changes in XCode 5.1.
So to fix this issue you need add -w flag to ZXingWidget Other Warning Flags. This flag completely disable all compiler warnings. Select ZXingWidget framework. Select ZXingWidget target in ZXingWidget framework. Press Build setting tab and type "other wa" in search. Add -w parameter flag to Other Warning Flags. Here is a screen with steps how to add this flag: http://stackoverflow.com/questions/22411565/build-error-on-ios-7-1-zxing |
