-(void)captureresult:(zxcapture *)capture result:(zxresult *)result {     if (!result) return;     // got result. display information result onscreen.     nsstring *formatstring = [self barcodeformattostring:result.barcodeformat];      nsstring *display = [nsstring stringwithformat:@"scanned!\n\nformat:      %@\n\ncontents:\n%@", formatstring, result.text]; }
