iOS QR code scan

I'm using the Zbar QR code to scan the other SDK can also

The first is to import the library file:

1.avfoundation.framework

2.coremedia.framework

3.corevideo.framework

4.quartzcore.framework

5.libiconv.dylib

This 5 library file

Import #import "ZBarSDK.h" in ViewController.h and inherit <ZBarReaderDelegate> protocol
