Question

我将以下功能与Zbar文件一起使用，以拍摄条形码的照片

- (IBAction)scanUPCBtnActn:(id)sender {
    //check camera available or not 
    if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
    {
        reader = [ZBarReaderViewController new];
        reader.readerDelegate = self;
        reader.supportedOrientationsMask = ZBarOrientationMaskAll;

    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];

    UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;
    if (UIDeviceOrientationLandscapeLeft == orientation)
    {
        //Rotate 90
        reader.cameraViewTransform = CGAffineTransformMakeRotation (4*M_PI/2.0);
    } else if (UIDeviceOrientationLandscapeRight == orientation) {
        //Rotate 270
        reader.cameraViewTransform = CGAffineTransformMakeRotation (4*M_PI/2.0);
    }
    // present and release the controller
    [self.navigationController presentViewController:reader animated:YES completion:nil];


}
else
{
    UIAlertView *cameraAlert=[[UIAlertView alloc]initWithTitle:@"Camera Alert" message:@"Camera Not Available" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
    [cameraAlert show];
}

}

我在我的项目中有zbar的文件，但是当我单击“提交”按钮时，它会打开相机，但是它不显示图标相机来拍照，而且我不知道我是否有手动添加此按钮或将其添加到zbar文件中，因为我没有可添加此按钮的屏幕或界面。任何帮助将不胜感激！谢谢

使用UIImagePickerController和Zbar扫描条形码不会向我显示图标相机
