Question

我正在尝试 iOS 并使用 Xamarin Forms..问题是 that.i 根本不知道 swift..

@objc func scanDocument()
        {
            let testViewController = ViewControllerCamer()
            testViewController.delegate = self
            present(scannler, animated: true)
        }

Answer 1

在 Xamarin 中我们需要像下面这样实现协议

public class MyDelegate : VNDocumentCameraViewControllerDelegate
{
    public override void DidFinish(VNDocumentCameraViewController controller, VNDocumentCameraScan scan)
    {
        base.DidFinish(controller, scan);
       //do something you want
    }

    public override void DidCancel(VNDocumentCameraViewController controller)
    {
        base.DidCancel(controller);
    }

    public override void DidFail(VNDocumentCameraViewController controller, NSError error)
    {
        base.DidFail(controller, error);
    }
}

VNDocumentCameraViewController control = new VNDocumentCameraViewController();

control.Delegate = new MyDelegate();
