ios - 如何创建一个以数组为对象的字典？

Question

class MyClass {

    var lists = Dictionary<String, Any>()

    init(){
        lists["lobby"] = [Int]()
        lists["events"] = [Int]()
        lists["missed"] = [Int]()
    }


    func isInsideList(id: Int, whichList: String) -> Bool{ //whichList could be "lobby", "events", or "missed"
        //check if "id" is inside the specified array?
       if let theList = lists[whichList] as? Array {  //this throws an error
           if theList.contains(id) ......
       }
    }
}

我怎样才能做到这一点？

Answer 1

func isInsideList(id: Int, whichList: String) -> bool {

if let theList = lists[whichList] as? [Int] {  

  if theList.contains(id) {

        return true
    }
}

return false
