ZBARSDK using two-dimensional code scanning recognition

Import the necessary framework

1. Quick Integration

Implementing the Zbarreaderdelegate Protocol

QR Code recognition-(void) sysbutbuttonclick{    //Initialize camera controller      zbarreaderviewcontroller *reader = [zbarreaderviewcontroller new];         //Setup Agent     reader.readerDelegate = self;     //Basic Fit     reader.supportedOrientationsMask = ZBarOrientationMaskAll;         //QR Code/barcode Recognition Settings     zbarimagescanner * Scanner = reader.scanner;        [scanner setsymbology:  ZBAR_I25                    config: ZBAR_CFG_ENABLE                        to: 0];     //pop-up system camera, full screen shooting      [Self presentviewcontroller:reader animated:yes completion:nil];} -  (void)  imagePickerController:  (uiimagepickercontroller*)  reader   didfinishpickingmediawithinfo:  (nsdictionary*)  info {              nslog (@ "info=%@", info);          //  Get Barcode Results          id<NSFastEnumeration>  results =[info objectforkey: zbarreadercontrollerresults];          ZBarSymbol *symbol = nil;          for (symbol in results)                   // EXAMPLE: just grab the first barcode             &Nbsp;    break;       nslog (@ "%@", Symbol.data);} 

2 Customizing Windows

Implementing the Zbarreaderviewdelegate Protocol

QR Code recognition-(void) sysbutbuttonclick{        //Initialize camera window      ZBarReaderView *readview = [ZBarReaderView new];         //Custom Size     readview.frame = myscreen;    // Custom Add related instructions ..... Play the imagination of the respective app     //here omit to beautify the 10000 lines of code .... ...     //... ..... ..... ........ ...............     //  good to go to the point--  then set up a proxy     readview.readerdelegate =  self;        //add its camera capture view to the view you want to display     [ self.view addsubview:readview];            // QR Code/Barcode Recognition Settings     ZBarImageScanner *scanner = readview.scanner;         [scanner setSymbology: ZBAR_I25                    config: zbar_cfg_enable                         to: 0];        //boot, must start after The real-time images taken by mobile phone photographers can be displayed on Readview     [readview start];} -(void) Readerview: (zbarreaderview *) Readerview didreadsymbols: (zbarsymbolset *) symbols  FromImage: (uiimage *) image{    zbarsymbol *symbol = nil;     for  (Symbol in symbols)  {        break ;     }        nslog (@ "========%@==========", Symbol.data);}
