In Android, I used zxing for bar code scanning. Now I found a free and open-source bar code scanning SDK for iPhone. The following describes how to use this SDK. The free bar code is zbar and its address is: http://zbar.sourceforge.net/iphone/sdkdoc/install.html The following figure shows the implementation result: The QR code can be used to obtain the value of the QR code. The specific implementation process is as follows: First download the zbr SD

Mobile devices such as mobile phones have become a good application platform for QR codes, whether generating or scanning QR codes. The following describes how to use a QR code on an apple iOS device: 1. Scan the QR code (Decoding)There are many open-source libraries for scanning QR codes, such as zbar and
