Question

我有一个预编译的静态库，用于扫描Scanner中的指纹。我可以轻松地将命令提供给扫描仪，它连接到我的应用程序，但我没有得到库的响应。库

没有执行覆盖方法

这是ApiDefinitions.cs文件的代码：

和struts.cs看起来像：使用System;

namespace ScanningLibrary
{
}

视图中的实现Controller是

using System;
using CoreGraphics;
using UIKit;
using ScanningLibrary;
using Foundation;

namespace testController.iOS
{
public class CustomViewController : IdentiFI_45_Delegate
{

    IdentiFI_45 myIdentiFI_45_Device = new IdentiFI_45();

    readonly UIViewController parent;

    public CustomViewController(UIViewController parent)
    {
        this.parent = parent;
        ViewDidLoad();
    }

    public  void ViewDidLoad()
    {
        myIdentiFI_45_Device.SetDelegate(parent);


        parent.View.BackgroundColor = UIColor.White;
        parent.Title = "My Custom View Controller";

        var btn_Connect = UIButton.FromType(UIButtonType.System);
        btn_Connect.Frame = new CGRect(20, 100, 280, 44);
        btn_Connect.SetTitle("Connect", UIControlState.Normal);

        var btn_Disonnect = UIButton.FromType(UIButtonType.System);
        btn_Disonnect.Frame = new CGRect(20, 130, 280, 44);
        btn_Disonnect.SetTitle("DisConnect", UIControlState.Normal);

        var btn_Battery = UIButton.FromType(UIButtonType.System);
        btn_Battery.Frame = new CGRect(20, 160, 280, 44);
        btn_Battery.SetTitle("Get Battery Level", UIControlState.Normal);

        btn_Connect.TouchUpInside += (sender, e) =>
        {
            myIdentiFI_45_Device.Connect();
        };

        btn_Disonnect.TouchUpInside += (sender, e) =>
        {
            myIdentiFI_45_Device.Disconnect();
        };

        btn_Battery.TouchUpInside += (sender, e) =>
        {
            myIdentiFI_45_Device.GetBatteryLevel();
            myIdentiFI_45_Device.GetFpPowerStatus();

        };

        parent.View.AddSubview(btn_Connect);
        parent.View.AddSubview(btn_Disonnect);
        parent.View.AddSubview(btn_Battery);

    }

    public override void OnCancelCapture()
    {
        throw new NotImplementedException();
    }

    public override void OnConnection()
    {
        //throw new NotImplementedException();
    }

    public override void OnDisconnection()
    {
        throw new NotImplementedException();
    }

    public override void OnGetBatteryLevel(float level)
    {
        throw new NotImplementedException();
    }

    public override void OnGetDeviceSerialNumber(string serialNumber)
    {
        throw new NotImplementedException();
    }

    public override void OnGetFirmwareVersion(string version)
    {
        throw new NotImplementedException();
    }

    public override void OnGetFpPowerStatus(byte fpPowerStatus)
    {
        throw new NotImplementedException();
    }

    public override void OnGetModelNumber(string model)
    {
        throw new NotImplementedException();
    }

    public override void OnGetReaderDescription(string deviceDescription)
    {
        throw new NotImplementedException();
    }

    public override void OnGetWSQEncodedFingerprintImage(NSData wsqEncodedFingerprintImageData)
    {
        throw new NotImplementedException();
    }

    public override void OnLastFrame(UIImage fpImage)
    {
        throw new NotImplementedException();
    }

    public override void OnLastFrame(NSData rawFpImageData, int nfiqScore)
    {
        throw new NotImplementedException();
    }

    public override void OnSetFpPowerOff()
    {
        throw new NotImplementedException();
    }

    public override void OnSetFpPowerOn(byte fpPowerStatus)
    {

    }

    public override void OnStreaming(UIImage fpImage)
    {
        throw new NotImplementedException();
    }

 }

正如@SushiHangover所说，您错误地使用了IdentiFI_45_Delegate。

此方法SetDelegate应设置为IdentiFI_45_Delegate，但您要将其分配给UIViewController。

解决方案：

public class CustomViewController : IdentiFI_45_Delegate
{

    IdentiFI_45 myIdentiFI_45_Device = new IdentiFI_45();

    public void ViewDidLoad()
    {
        myIdentiFI_45_Device.SetDelegate(this);
        btn_Connect.TouchUpInside += (sender, e) =>
        {
            myIdentiFI_45_Device.Connect();
        };
        //xxx
    }

    //Delegate Method 
    public override void OnConnection()
    {            
    }
}
