QR Code barcode scanning using IOS7 native API prior to IOS7, developers typically use third-party libraries for code-scanning programming. commonly used is the ZBarsdk,ios7 after , the system's Avmetadataobject class, we provide an interface for parsing two-dimensional code. Tested, the use of native API scanning and processing is very efficient, far higher than the third-party library. I. Examples of usage methods The official interface is very

Barcodes are the vertical strips that we see on the merchandise.I wouldn't have been interested in that if I hadn't used this on the project.

This simple question bothered me for nearly two hours, the main is the official document did not find the demo, that can only use search engines, see other programmers to write the program, but found everywhere is a pit, see four or five examples, no one can be normal operation, all the error, after one hours of trial, only to finish. Not much to say, directly on the screenshot and code. First, add the Zxing.dll reference to the project (zxing.dll download address http://www.jb51.net/dll/zxing.
