Question

我有一个这样的字典：

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

存储这个键和值我已经创建了一个关键字的数组和这样的值：

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

并将键和值保存到数组中：

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

这是我的defaultName Model类：

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

现在我如何打印设置值的值，如..

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)

            }
        }

我看到你正在使用EVReflection（EVObject是你的基本类型）。然后，您可以基于字典启动对象。为什么不把数据的值放在字典中呢？更好的是，为什么不用常规属性而不是键和值属性创建对象。以下是一些有效的示例代码：

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?
}

Swift：比较字典键
