Make a Property for the reader and when you call it multiple times you can check, if a Object of the reader where initialize ...
Here is what i´m doing:

- (IBAction)ShowZBarReader
{
    // ADD: present a barcode reader that scans from the camera feed
    if (!self.reader) {
        self.reader = [[ZBarReaderViewController alloc]init];
    }

    self.reader.readerDelegate = self;
    self.reader.supportedOrientationsMask = ZBarOrientationMaskAll;

    ZBarImageScanner *scanner = self.reader.scanner;
    //  zusätliche Configurationen ...

    [scanner setSymbology: ZBAR_I25
                   config: ZBAR_CFG_ENABLE
                       to: 0];
    // stellt Bild zur verfügung
    [self presentViewController:self.reader animated:YES completion:nil];
}

Worked perfectly for me ! Hope it helps :)
