如何使用ZBar SDK掃描QR碼時去除綠色矩形？

Question

- (IBAction)scanProduct:(id)sender 
{ 
    // for scanning product 
    ZBarReaderViewController *reader = [[ZBarReaderViewController alloc] init]; 
    reader.readerDelegate = self; 
    reader.supportedOrientationsMask = ZBarOrientationMaskAll;  
    ZBarImageScanner *scanner = reader.scanner;  
    [scanner setSymbology: ZBAR_I25 
           config: ZBAR_CFG_ENABLE 
            to: 0];  
    [self presentModalViewController: readerqr 
             animated: YES]; 
} 

當點擊按鈕readerqr時出現綠色的矩形。

看着the documentation for ZBarReaderViewController，它看起來像設置tracksSymbols到NO可能會伎倆。
