Problems and solutions that are easy to encounter when ZBar is integrated, and the zbar solution is integrated

1. Add several necessary frameworks:

Libiconv. tbd

QuartzCore. framework

CoreVideo. framework

CoreMedia. framework

AVFoundation. framework

2. Remember to add the integrated libzbar. a file to viewControllers.

3. If your project contains precompiled files

Other classes are also referenced in the pre-compiled file.

Required: Add # endif when the # ifdef _ OBJC _ header file is referenced. For example

# Ifndef PureStandard_PrefixHeader_pch
# Define PureStandard_PrefixHeader_pch

# Ifdef _ OBJC __

// Header file to be introduced
# Import "A. h"
# Import "B. h"

# Endif

// Use # ifdef _ OBJC _ # endif modifier # import reference header file

// Indicates that files referenced in the macro are referenced only by objects in Objective-C language, and the reference relationship is clear.

 

4. If a compilation Link error occurs, you can change the Bitcode to NO in build setting.
