Paste "M1, M2" methods in your view controller (i.e. "ViewController.m")

"M1" viewDidLoad, viewWillAppear, viewWillDisappear

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    [qrCodeView setDelegate:self];
}

- (void)viewWillAppear:(BOOL)animated {
    if (!qrCodeView.isRunning) {
        [qrCodeView startReading];
    }
}

-(void)viewWillDisappear:(BOOL)animated {
    // stop reading
    [qrCodeView stopReading];
}

And here the delegate methods:

"M2" V3QRCodeReaderDelegate

#pragma mark - V3QRCodeReaderDelegate
- (void)getBarCodeData:(NSDictionary *)scanDictonary {
    NSLog(@"scanDictonary : %@",scanDictonary);
    
    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:[scanDictonary valueForKey:@"barCodeType"] message:[scanDictonary valueForKey:@"barCodeValue"] preferredStyle:UIAlertControllerStyleAlert];
    UIAlertAction *cancel = [UIAlertAction actionWithTitle:@"Close" style:UIAlertActionStyleDefault handler:nil];
    [alertController addAction:cancel];

    // Get Screenshot of Barcode
    if ([scanDictonary valueForKey:@"image"]) {
        /* scan image
        UIImageView *imgView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 200, 100)];
         */
    }
    
    UIAlertAction *reScan = [UIAlertAction actionWithTitle:@"Rescan" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
        [self reScanBarCode];
    }];
    
    [alertController addAction:reScan];
