如何在Swift中创建接口 [英] How to create an interface in Swift

问题描述

我想快速创建类似接口的功能，我的目标是当我调用另一个类时假设我正在调用API，并且该类的响应我想反映到当前屏幕中，因此在android接口中用于实现但是我该如何快速使用呢?谁能帮我举个例子. android的代码在下面给出...

i want to create functionality like interface in swift, my goal is when i call another class suppose i'm calling API and the response of that class i want to reflect in to my current screen, in android interface is used to achieve but what should i use in swift for that? can anyone help me with example. the code for android is given below...

public class ExecuteServerReq {
    public GetResponse getResponse = null;

    public void somemethod() {
        getResponse.onResponse(Response);
    } 
    public interface GetResponse {
        void onResponse(String objects);
    }
}


ExecuteServerReq executeServerReq = new ExecuteServerReq();

executeServerReq.getResponse = new ExecuteServerReq.GetResponse() {
    @Override
    public void onResponse(String objects) {
    }
}

推荐答案

而不是界面swift拥有协议.

Instead of interface swift have Protocols.

协议定义了适合特定任务或功能的方法，属性和其他要求的蓝图.然后，该协议可以由类，结构或枚举采用，以提供这些要求的实际实现.满足协议要求的任何类型都被认为符合该协议.

A protocol defines a blueprint of methods, properties, and other requirements that suit a particular task or piece of functionality. The protocol can then be adopted by a class, structure, or enumeration to provide an actual implementation of those requirements. Any type that satisfies the requirements of a protocol is said to conform to that protocol.

让我们参加考试.

protocol Animal {
    func canSwim() -> Bool
}

并且我们有一个确认此协议名称为Animal

and we have a class that confirm this protocol name Animal

class Human : Animal {
   func canSwim() -> Bool {
     return true
   }
}
