After investigation of all commentaries in
How to install ZXing in Xcode 4 I finally solved a problem of “ZXingWidgetController.h not found”. But to totally solve it, you must do several things and none of the commentaries contain them all. So I decided to write here, what you should do to finally solve this problem. So,
- Your full project path should not contain space characters. For example, “AppName 1.0” is not correct. You should use “AppName_1.0” or “AppName1.0”. This is because the search of header paths and user header paths doesn’t work properly otherwise.
- Let’s assume that your zxing folder is located in the root of your app folder. Then your header search paths should be something like this:
For copy paste purposes:
123${SRCROOT}/zxing/iphone/ZXingWidget/Classes${SRCROOT}/zxing/cpp/core/src${SDKROOT}/usr/include/libxml2 - You should repeat this also for User Header Search Paths

Don’t forget to check a compiler for ZXingWidget Project. It might be old GCC compiler. It must be edited to Apple LLVM Compiler:
Also, it is very important, that you have only one copy of source files in the directory of application project. Otherwise, you might get errors like this.
