self.title = @"QR Code Reader";
[qrCodeView setDelegate:self];
[qrCodeView startReading];
}

And here the delegate methods:

"M2" QRCodeReaderDelegate

#pragma mark - QRCodeReaderDelegate
- (void)getQRCodeData:(id)qRCodeData {
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"QR Code" message:qRCodeData preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *cancel = [UIAlertAction actionWithTitle:@"Close" style:UIAlertActionStyleDefault handler:nil];
[alertController addAction:cancel];

UIAlertAction *reScan = [UIAlertAction actionWithTitle:@"Rescan" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
[qrCodeView startReading];
}];
[alertController addAction:reScan];
[self presentViewController:alertController animated:YES completion:nil];
