An easy application for create and scan QR code on iOS using Xamarin.iOS
You can create a QRCode by using this code:
UIimage qrCodeImage = QRCodeCreater.Instance().GetQRCodeImageByString(sourceStr,showQRCodeImgView.Frame.Width);
And you can scan a QRCode by using the Extension Methods in every UIViewController like:
this.ShowQRCodeReaderViewController((result)=>{
UIAlertView alert = new UIAlertView("Result",result,null,"OK",null);
alert.Show();
});
Or the origin method, like:
QRCodeReaderViewController.Intance().Show(controller.NavigationController,(result)=>{
UIAlertView alert = new UIAlertView("Result",result,null,"OK",null);
alert.Show();
});
This are some screenshot showing the effect:
