问题描述

我遇到的问题是我收到错误。

And the issue I am having is I keep getting the error.

类型任何没有下标成员错误在此函数...

"Type Any has no subscript members Error" in this function...

func allItems() -> [TodoItem] {
let todoDictionary = NSUserDefaults.standardUserDefaults().dictionaryForKey(ITEMS_KEY) ?? [:]
let items = Array(todoDictionary.values)
return items.map({TodoItem(deadline: $0["deadline"] as! NSDate, title: $0["title"] as! String, UUID: $0["UUID"] as! String!)}).sort({(left: TodoItem, right:TodoItem) -> Bool in
        (left.deadline.compare(right.deadline) == .OrderedAscending)
}

该行正在生成错误...

The error is being generated on this line...

return items.map({TodoItem(deadline: $0["deadline"] as! NSDate, title: $0["title"] as! String, UUID: $0["UUID"] as! String!)}).sort({(left: TodoItem, right:TodoItem) -> Bool in
        (left.deadline.compare(right.deadline) == .OrderedAscending)}

我完全陷入困境。

任何帮助将不胜感激！谢谢！

Any help would be appreciated! Thank you!

推荐答案

您需要明确指定类型的项目对象为 [[String：Any]] 。

You need to explicitly specify the type of items object as [[String:Any]].

let items = Array(todoDictionary.values) as! [[String: Any]]
