ios - 使用Swift语法收听Objective-C回调

我有一个看起来像这样的Objective-C回调。

//APIClient.h
typedef void (^DetailSearchFinishedCallBack)(RestaurantDetailModel *detailModel);

//Called in a different class as follows.

@property (nonatomic, copy)   DetailSearchFinishedCallBack detailSearchFinishedCallBack;

self.detailSearchFinishedCallBack(nil);

在Swift类中，我希望能够侦听此回调，但是在查找此调用的正确语法时遇到了麻烦。这是我的快速代码:

lazy var apiClient: APIClient =
    {
        var apiClient : APIClient = APIClient()

        //TODO: Set up callback listener here.

        return apiClient
    }()

我检查了这篇文章:
What's the equiv. Swift Closure-Callback to Objective-C's block callback?

但是该块是在本地定义的，而我的块是在apiClient中定义的。如果有人可以帮助我，我将不胜感激。

最佳答案

我认为类似这样的东西应该可以代替TODO

apiClient.detailSearchFinishedCallBack = { detailModel in
    // Do something with detailModel if not nil
}

detailModel的类型将被推断，但您也可以是明确的

apiClient.detailSearchFinishedCallBack = { (detailModel: RestaurantDetailModel!) in
    // Do something with detailModel if not nil
}
