Configure the Barcode control

The following steps explain you how to create and configure a Barcode.

  1. Add reference to the SfBarcode in view controller as follows.

After installing Essential Studio for Xamarin, you can find all the required assemblies in the installation folders, typically: {Syncfusion Installed location}\Essential Studio{version number}\lib
You have to add the following assembly reference to the iOS unified project ios-unified \ Syncfusion.SfBarcode.iOS.dll

NOTE

Assemblies are available in unzipped package location in Mac.

2.Create an instance of SfBarcode in view controller and add it as sub view in viewDidLoad override method.

  • c#
  • public override void ViewDidLoad ()
            {
                base.ViewDidLoad ();            
                SFBarcode barcode = new SFBarcode ();
                this.View.AddSubview (barcode);
            }

    3.Then you can assign the text that you want to encode.

  • c#
  • barcode.Text  =   (NSString)"www.wikipedia.org";

    4.Specify the required symbology to encode the given text. By default, the given text is encoded by using the Code39 symbology.

  • c#
  • barcode.Symbology  =  SFBarcodeSymbolType.SFBarcodeSymbolTypeQRCode;

    5.To customize the Barcode, initialize the settings of the corresponding Barcode symbology.

  • c#
  • SFQRBarcodeSettings settings  =  new SFQRBarcodeSettings  ();       
        settings.XDimension  =  6;      
        barcode.SymbologySettings  =  settings;

    6.Finally, the Barcode is generated as displayed in the screenshot by using the following code example.

  • c#
  • public override void ViewDidLoad ()
            {
                base.ViewDidLoad ();
                SFBarcode barcode = new SFBarcode ();
                barcode.Text  =   (NSString)"www.wikipedia.org";
                barcode.Symbology  = SFBarcodeSymbolType.SFBarcodeSymbolTypeQRCode;    
                SFQRBarcodeSettings settings  = new SFQRBarcodeSettings  ();       
                settings.XDimension  =  6;      
                barcode.SymbologySettings  =  settings;
                this.View.AddSubview (barcode);
            }
