zxing连续扫描 - iphone [英] zxing continuous scanning - iphone

问题描述

我已将zxing库集成到我的应用程序中，但我的部分要求是能够连续扫描QR码。
我通过解雇和重新呈现zxing小部件已经在一定程度上实现了这一点，但对我的客户来说似乎太慢了。
还有另一种方法可以重置小部件以重新开始扫描吗？

I've integrated the zxing library into my app but part of my requirement is to be able to continually scan QR codes. I've accomplished this to a certain degree by dismissing and re-presenting the zxing widget but it appears to be too slow for my client. Is there another way to reset the widget to start scanning again?

推荐答案

你将不得不篡改ZXing图书馆，幸运的是，这并不难。

You will have to tamper with the ZXing library, fortunately it's not hard.

将以下方法添加到ZXingWidgetController

Add the following method to the ZXingWidgetController

在ZXingWidgetController.h中

In ZXingWidgetController.h

- (void)reset;

在ZXingWidgetController.m中

In ZXingWidgetController.m

- (void)reset
{
    decoding = YES;
    [overlayView setPoints:nil];
    wasCancelled = NO;
}

现在，在您的ZXing委托中，编辑以下方法

Now, in your ZXing delegate, edit the following method

- (void)zxingController:(ZXingWidgetController*)controller didScanResult:(NSString *)result
{
    //Handle your result as you want to

    [controller reset];
}

确保你没有打电话给 [self dismissModalViewControllerAnimated ：NO]; 因为它将删除扫描视图。

Make sure you don't call [self dismissModalViewControllerAnimated:NO]; as it will remove the scanning view.
