Question

func setPostcommentData(postmodel:model1,index: IndexPath) {
     btnReply.tag = index.section
     lblName.text = postmodel.getFullName()
     btnReply.setTitle("Reply", for: UIControlState.normal)
     btnCount.setTitle("0", for: UIControlState.normal)
     TxtViewComment.text = postmodel.description
     lblTime.text = ChatDates.commentTimeData(postmodel.createdDate).dateString
}

用法：

cellComment.setPostcommentData(postmodel: model1,index:indexPath) 
cellComment.setPostcommentData(postmodel: model2,index:indexPath) 
cellComment.setPostcommentData(postmodel: model3,index:indexPath)

如何编写通用函数以便它接受不同的模型并设置数据？

如果我的想法正确，这是一个解决方案

protocol PostComment {
    var value1: String {get}
    var value2: String {get}
    var value3: String {get}
}

class PostCommentParent: PostComment {
    var value1: String {
        return self.myValue1
    }

    var value2: String {
        return self.myValue2
    }

    var value3: String {
        return self.myValue3
    }

    var myValue1 = "1"
    var myValue2 = "2"
    var myValue3 = "3"
}

class PostCommentChild: PostCommentParent {
    override var value3: String {
        return self.myValue4
    }

    var myValue4 = "4"
}

let myParent = PostCommentParent()
let myChild = PostCommentChild()

func parse(comment: PostComment) {
    print(comment.value3)
}

parse(comment: myChild)
parse(comment: myParent)

如何为不同的类编写通用泛型函数？
