我有这门课

class InboxInterests {

    var title = ""
    var eventID = 0
    var count = ""
    var added = 0

    init(title : String, eventID : NSInteger, count: String, added : NSInteger) {
        self.title = title
        self.eventID = eventID
        self.count = count
        self.added = added

    }
}

我就是这样用的

var array: [InboxInterests] = [InboxInterests]()

新增项目

let post = InboxInterests(title: "test",eventID : 1, count: "test", added: 0)
self.array.append(post)

我想eventID按键找到索引并added在同一索引中更改key的值

怎么可能？
