IOS QR code scan through ZBar ZXing and other third-party libraries, zbarzxing There are many open-source libraries for scanning QR codes, such as ZBar and ZXing. How to Use ZBar: Download ZBar SDK Address https://github.com/bmorton/ZBarSDK ZBarSDK is an open source SDK that implements the identification and reading of various bar codes, including EAN-13/UPC-A,

next, because using avfoundation has been unable to scan our QR code, and finally decided to use a barcode. I added the EAN13 barcode type (the type we used to generate the barcode) in Avcapturemetadataoutput's metadataobjecttypes, unfortunately, is still not recognized, but Baidu's other EAN13 types of barcodes can be identified, this issue is still unresolved. Finally, I decided to try Zbar,bingo!. The

Business Scenarioswhen a QR code scan is implemented ( with a zbar), sometimes the entire scanned image needs to be stored quietly, and (as Charles has some perverted business) that means a panoramic picture of the scanned picture. So how is the code implemented? I went to StackOverflow finally found the way to achieve! protected Previewcallback PREVIEWCB = new Previewcallback () {public void Onpreviewfra
