如何在Xamarin iOS中符合协议

问题描述

强文本我正在Xamarin中实现iZettle支付SDK。我创建了绑定库，并将所有头文件转换为ApiDefintions。 我一直坚持在Xamarin中遵守iZettleSDKAuthorizationProvider协议。

这是我的APIDeFinition.cs文件代码；

[BaseType(typeof(NSObject))]
[Model,Protocol]
interface iZettleSDKAuthorizationProvider
{
    // @required -(void)authorizeAccountWithCompletion:(void (^ _Nonnull)(iZettleSDKOAuthToken * _Nullable,NSError * _Nullable))completion;
    [Abstract]
    [Export("authorizeAccountWithCompletion:")]
    void AuthorizeAccountWithCompletion(Action<iZettleSDKOAuthToken,NSError> completion);

    // @required -(void)verifyAccountWithUuid:(NSUUID * _Nonnull)uuid completion:(void (^ _Nonnull)(iZettleSDKOAuthToken * _Nullable,NSError * _Nullable))completion;
    [Abstract]
    [Export("verifyAccountWithUuid:completion:")]
    void VerifyAccountWithUuid(NSUuid uuid,Action<iZettleSDKOAuthToken,NSError> completion);
}

// @interface iZettleSDKAuthorization : NSObject <iZettleSDKAuthorizationProvider>
[BaseType(typeof(NSObject),Name = "_TtC10iZettleSDK23iZettleSDKAuthorization")]
[disableDefaultCtor]
interface iZettleSDKAuthorization : IiZettleSDKAuthorizationProvider
{
    // -(instancetype _Nullable)initWithClientID:(Nsstring * _Nonnull)clientID callbackURL:(NSURL * _Nonnull)callbackURL error:(NSError * _Nullable * _Nullable)error enforcedUserAccount:(Nsstring * _Nullable (^ _Nonnull)(void))enforcedUserAccount __attribute__((objc_designated_initializer));
    [Export("initWithClientID:callbackURL:error:enforcedUserAccount:")]
    [DesignatedInitializer]
    IntPtr Constructor(string clientID,NSUrl callbackURL,[NullAllowed] out NSError error,Func<Nsstring> enforcedUserAccount);
}

简而言之，我想要Xamarin ios等效于以下代码；

 id<iZettleSDKAuthorizationProvider> authorizationProvider = [[iZettleSDKAuthorization alloc]
                           initWithClientID:clientId
                           callbackURL:[NSURL URLWithString:callbackURL]
                           error:&error
                           enforcedUserAccount:^Nsstring * _Nullable{
    return [AccountManager shared].enforcedUserAccount;
}];

为shown here。这样任何人都可以帮助我，那就太好了。
