ios - 从字典的 NSMutableArray 获取字典

Question

我正在尝试从 NSMutableArray 获取 NSMutableDictionary。

我这样设置数组:

let test : NSMutableDictionary = NSMutableDictionary()
    test.setValue("Monday", forKey: "day")
    test.setValue("7PM - 8PM", forKey: "hour")

    self.availabilityArray.add(test)

    let test1 : NSMutableDictionary = NSMutableDictionary()
    test1.setValue("Saturday", forKey: "day")
    test1.setValue("8PM - 10PM", forKey: "hour")
    self.availabilityArray.add(test1)

    let test2 : NSMutableDictionary = NSMutableDictionary()
    test2.setValue("Sunday", forKey: "day")
    test2.setValue("2PM - 8PM", forKey: "hour")
    self.availabilityArray.add(test2)

在另一种方法中，我尝试获取“日”和“小时”值以在 UILabel 中设置它们。

我尝试过这样做:

let dico = self.availabilityArray[i] //i being the index of a loop, not important here
self.dayNameLabel.text = (dico as AnyObject).object(forKey:"day") // This line does not work, I want to do something like that.

那么如何获取 NSMutableArray 的内容作为 NSDictionary 的精确索引？

谢谢。

感谢 Larme，我找到了解决方案，我只需更换

self.dayNameLabel.text = (dico as AnyObject).object(forKey:"day")

与

self.dayNameLabel.text = (dico as! NSMutableDictionary).object(forKey:"day") as! String?
