我需要在应用程序中集成QR码阅读器并找到它的教程.

我从这个链接下载了Z-bar sdk .

这就是我所做的.

在QRscannerViewController.m中

-(IBAction)StartScan:(id) sender
{
    ZBarReaderViewController *reader = [ZBarReaderViewController new];
     reader.readerDelegate = self;

     reader.readerView.torchMode = 0;

    ZBarImageScanner *scanner = reader.scanner;
    // TODO: (optional) additional reader configuration here

    // EXAMPLE: disable rarely used I2/5 to improve performance
    [scanner setSymbology: ZBAR_I25
     config: ZBAR_CFG_ENABLE
      to: 0];

     // present and release the controller
     [self presentModalViewController: reader
       animated: YES];
     [reader release];

    resultTextView.hidden=NO;
 }

 - (void) readerControllerDidFailToRead: (ZBarReaderController*) reader
                         withRetry: (BOOL) retry{
     NSLog(@"the image picker failing to read"); …
