var imgsrc: String = "" ///< store user's name, optional
var title: String = "" ///< store user's telephone number
var replyCount: Int = 0
//方法二的model
override init() {
super.init()
}
func setModel(_ imageUrl: String ,_ contentStr: String, _ replyCount:Int) {
self.imageUrl = imageUrl
self.contentStr = contentStr

}
}

2. 利用swift自有的函数进行解析-------推荐
