Swift：比較字典鍵

Question

我有一本這樣的字典：

var dataDictionary : [String:String] = ["Result" : "result", "Date Added" : "dateAdded", "Entered By" : "enteredBy"]

為了存儲這個鍵和值，我已經將一個數組和一個鍵和值做成了數組：

var selectedDictKeys :[String] = [String]()
var selectedDictValues :[String] = [String]()

並將鍵和值保存在數組中，如下所示：

self.selectedDictKeys = Array(self.dataDictionary.keys)
self.selectedDictValues = Array(self.dataDictionary.values)

這是我的defaultName模型類：

class DefaultNameModel: EVObject {
    var key : String = ""
    var value : String = ""
}

現在我該如何打印為類似的值設置值。

self.selectedDictKeys = Array(self.dataDictionary.keys)
self.selectedDictValues = Array(self.dataDictionary.values)

var dataSet = [DefaultNameModel]()
for i in 0...(self.selectedDictKeys.count-1) 
{
    let dataRow = DefaultNameModel()
    dataRow.key = String(self.selectedDictKeys)

    if dataRow.key == "Result"
    {
        dataRow.value == "Success"
        dataSet.append(dataRow)
        print("The data Row is\(dataRow)")           
    }

    if dataRow.key == "Date Added"
    {
        dataRow.value == "2016-12-12"
        dataSet.append(dataRow)
        print("The data Row is\(dataRow)")   
    }

    if dataRow.key == "Entered By"
    {
        dataRow.value == "Me"
        dataSet.append(dataRow)
        print("The data Row is\(dataRow)")
    }
}

Answer 1

for key in self.selectedDictKeys {
    let dataRow = DefaultNameModel()
    dataRow.key = key

    switch key {
    case "Result":
        dataRow.value == "Success"
    case "Date Added":
        dataRow.value == "2016-12-12"
    case "Entered By":
        dataRow.value == "Me"
    default:
        dataRow.value == ""
    }

    dataSet.append(dataRow)
    print("The data Row is\(dataRow)")
}

        var dataSet = [DefaultNameModel]()
        for i in self.selectedDictKeys
        {
            let dataRow = DefaultNameModel()
            dataRow.key = i

            if dataRow.key == "Result"
            {
                dataRow.value == "Success"
                dataSet.append(dataRow)
                print("The data Row is " + dataRow.Key + " " + dataRow.value)

            }

            if dataRow.key == "Date Added"
            {
                dataRow.value == "2016-12-12"
                dataSet.append(dataRow)
                print("The data Row is " + dataRow.Key + " " + dataRow.value)

            }
            if dataRow.key == "Entered By"
            {
                dataRow.value == "Me"
                dataSet.append(dataRow)
                print("The data Row is " + dataRow.Key + " " + dataRow.value)

            }
        }

我看到您正在使用EVReflection（EVObject是您的基本類型）。 然后，您可以基於字典啟動對象。 為什么不將數據的值放在字典中？ 更好的是，為什么不創建具有常規屬性而不是鍵和值屬性的對象。 這是一些有效的示例代碼：

func testxx() {
    // Why not setting the values in the dictionary?
    let dataDictionary: NSDictionary = ["Result" : "Success", "Date Added" : "2016-12-12", "Entered By" : "Me"]

    // Then you could just map it to the model using:
    let defaultNameModel: [DefaultNameModel] = dataDictionary.map { DefaultNameModel(dictionary: ["key": $0.key, "value": $0.value]) }
    print("defaultNameModelOld = \(defaultNameModel)")

    // But you could directly map it to a real model
    let defaultNameModelNew = DefaultNameModelNew(dictionary: dataDictionary)
    print("defaultNameModelNEw = \(defaultNameModelNew)")
}

class DefaultNameModel: EVObject {
    var key: String?
    var value: String?
}

class DefaultNameModelNew: EVObject {
    var Result: String?
    var Date_Added: String?
    var Entered_By: String?
}
