使用委托绑定方法

Question

我正在创建一个绑定库来绑定本机Objective-C框架.

我有以下委托,我需要将它的声明添加到ApiDefinition文件,然后我需要使用我的Xamarin.iOS应用程序实现它:

- (void)Initialize:(id <MMSDKDelegate> _Nullable)pDelegate;

MMSDKDelegate:

@protocol MMSDKDelegate <IMMDelegate>
- (void)Started;
@end

IMMDelegate:

@protocol IMMDelegate
- (void)Inserted;
- (void)Removed;
- (void)ReaderConnected;
- (void)ReaderRemoved;
@end

我需要ApiDefinition文件中的必需定义,我需要一个示例代码来从我的Xamarin.iOS应用程序调用此方法.

更新

我正在处理的框架是与连接iPhone的读卡器设备进行通信以读取ID卡信息,它具有在读取器插入/移除和插入/移除卡片时调用的方法.

我已经实现了@ cole-xia的答案,但问题是IMMDelegate我插入读卡器或ID时从未调用过里面的方法.当我打电话ReadCardData(),它应该调用Started()这将显示由保存的信息Inserted(),但目前的结果是,Started()方法调用后调用ReadCardData(),但Inserted()和ReaderConnected()在任何阶段都不会被调用.

在Framework的演示应用程序中,它用作以下(并且正常工作):

// Demo app -> ViewController.m

@interface ViewController () <MMSDKDelegate>

@end


@implementation ViewController {
    MMSDK *sdkInstance;
}


- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    sdkInstance = [MMSDK SharedInstance];
    [sdkInstance Initialize:self];
}


- (void)Started
{
    // Update UI by: reading in progress ..
}


- (void)Inserted
{
    // Update UI by: card inserted
    // And read card data
    [self readData:self];
}

- (void)Removed
{
    // Update UI by: card removed
}

- (void)ReaderConnected
{
    // Update UI by: card reader connected
}

- (void)ReaderRemoved
{
    // Update UI by: card reader removed
}


- (IBAction)readData:(id)sender
{
    var *data = [sdkInstance ReadCardData:YES pWithSignatureImage:YES pWithAddressData:YES];
    if (data.hasError) {
        // No data fetched
        return;
    }

    if (data) {
        // return card data
    }
}

欢迎并赞赏所有建议.

总之,我只需要在Xamarin.iOS应用程序中执行相同的演示应用程序功能.

使用Sharpie来创建 ApiDefinition

我这边的结果是：

// @protocol IMMDelegate
[BaseType (typeof (NSObject))]
[Protocol, Model]
interface IMMDelegate
{
    // @required -(void)Inserted;
    [Abstract]
    [Export ("Inserted")]
    void Inserted ();

    // @required -(void)Removed;
    [Abstract]
    [Export ("Removed")]
    void Removed ();
}

// @protocol MMSDKDelegate <IMMDelegate>
[BaseType (typeof (NSObject))]
[Protocol, Model]
interface MMSDKDelegate : IMMDelegate
{
    // @required -(void)Started;
    [Abstract]
    [Export ("Started")]
    void Started ();
}

// @interface ACR : NSObject
[BaseType (typeof(NSObject))]
interface YourClass
{
    // -(void)Initialize:(id<MMSDKDelegate> _Nullable)pDelegate;
    [Export ("Initialize:")]
    void Initialize ([NullAllowed] MMSDKDelegate pDelegate);
}

用法：

class MyDelegate : MMSDKDelegate {
    public void Started()
    {
    }

    public override void Removed()
    {
    }
    public override void Inserted()
    {
    }
}


//In ViewController

public override void ViewDidLoad()
{
    base.ViewDidLoad();

    YourClass yourClass = new YourClass();
    yourClass.Initialize(new MyDelegate());
}
