ios - 需要帮助更新 NSMutable 数组 - iOS Swift

Question

我有一个表格，其中填充了以下数据:

var vaccineEntry: NSMutableArray = [[
    ["name" : "Rabies 1-yr", "detail": "Set"],
    ["name" : "Rabies 3-yr", "detail": "Set"],
    ["name" : "Distemper", "detail": "Set"],
    ["name" : "Parvovirus", "detail": "Set"],
    ["name" : "Adenovirus", "detail": "Set"]],
[
    ["name" : "Parainfluenza", "detail": "Set"],
    ["name" : "Bordetella", "detail": "Set"],
    ["name" : "Lyme Disease", "detail": "Set"],
    ["name" : "Leptospirosis", "detail": "Set"],
    ["name" : "Canine Influenza", "detail": "Set"]
]]

var section = ["Core Dog Vaccines", "Non-Core Dog Vaccines"]

我的 tableview 方法正在运行，因为无论我在这些字典位置数组中放入什么，都会正确地填充我的表。但是，我的应用程序将根据 bool 值更新所有“详细信息”值，然后将其转换为字符串。我似乎无法找到正确的 NSMutable Array 方法来执行此转换。这是我的代码:

if object["expired"] as! Bool == true {

        let expiredTag: String = "Expired"

        self.vaccineEntry.setValue("Expired", forKey: "Rabies 1-yr")
        self.vaccineEntry.setValue(expiredTag, forKey: (name: "Rabies 1-yr"))
        self.vaccineEntry.setValue(expiredTag, forKeyPath: "Rabies 1-yr")
        self.vaccineEntry.valueForKeyPath("Rabies 1-yr")
        self.vaccineEntry.setValue("Expired", forKeyPath: "Rabies 1-yr")
        self.vaccineEntry.objectAtIndex(0).valueForKeyPath("name")
        self.vaccineEntry.setValue("Expired", forKey: "name")
        self.vaccineEntry.objectAtIndex(0).valueForKey("Rabies 1-yr")
        self.vaccineEntry.replaceObjectAtIndex(0, withObject: "Expired")
        let rabiesObject = ["name" : "Rabies 1-yr", "detail": "Expired"]
        self.vaccineEntry.replaceObjectAtIndex(0, withObject: rabiesObject)


 } else {

        let updatedTag: String = "Up To Date"

        self.vaccineEntry.setValue("UP to date", forKey: "name")
        self.vaccineEntry.objectAtIndex(0).valueForKey("Rabies 1-yr")

 }

这些都是我的尝试。它们都编译得很好，但我的表数据并没有改变我在顶部的原始输入(“Set”只是占位符文本)。在我进行尝试时，我对这些尝试中的每一个都进行了注释，仅供引用。非常感谢任何帮助!!
