In the age of the Internet of Things, the QR code is a very important thing, now no matter what things have to make a two-dimensional code sign, lest the outdated, the policeman did not use two-dimensional code recognition. Perhaps one day zoning card or hukou will be used to identify the two-dimensional

The scanned control is a view, and the user simply needs to stick it in their own controller. Other UI users can add them at their own controller. The code is as follows- (void) viewdidload {[Super viewdidload]; //Scan active area (i.e. transparent area within the box)CGRect Interestrect = CGRectMake ( -, (Self.view.frame.size.height-(Self.view.frame.size.width- +))/2.0f, Self.view.frame.size.width- +, Self.view.frame.size.width- +); //Scan Controls_s

Technology selectionIn order to solve the problem that the QR code cannot be scanned, the appropriate technical means must be chosen. Since our app refers to someone else's developed zbar-based image recognition plug-in, without the ability to modify the image recognition plug-in, I decided to solve this problem on the server side, considering the general type of the algorithm, in the service-side verificat

Recently doing a scan code login function, for this I also searched the internet about the implementation of the scan login. When this function was completed, I decided to organize the whole realization, so that I can see it later and also facilitate other programs with similar requirements.To implement a scan login we need to address two issues:1. How do I resolve a privilege security issue without entering a username and password? In other words, ho
