将[String：Any]字典数组转换为Swift中的[String：String]

我有一个字典<String,Any>类型的数组。现在我想转换为字符串，因为我想在textField中显示数据，而文本字段则不了解Any数据类型。

我的数据如下：

var myarr = [[String:Any]]()

[
    [
        "Area" : "",
        "Good" : "-",
        "Level" : 2,
        "Link" : "<null>",
        "Photo" : "-",
        "Repair" : "-",
        "Section" : "Others"
    ],

    [
        "Area" : "",
        "Good" : "N",
        "Level" : 2,
        "Link" : "http://google.com",
        "Photo" : 1,
        "Repair" : "Y",
        "Section" : "Grounds"
    ]

]

我想要新的Array Dictionary：

var myarr = [[String:String]]()

Answer 1

地图是你的朋友，也许就像

let stringDictionaries: [[String: String]] = myarr.map { dictionary in
    var dict: [String: String] = [:]
    dictionary.forEach { (key, value) in dict[key] = "\(value)" }
    return dict
}

Answer 2

这是一个实际给出正确结果的解决方案：

let myarr = [
    [
        "Area" : "",
        "Good" : "-",
        "Level" : 2,
        "Link" : "<null>",
        "Photo" : "-",
        "Repair" : "-",
        "Section" : "Others"
    ],

    [
        "Area" : "",
        "Good" : "N",
        "Level" : 2,
        "Link" : "http://someurl",
        "Photo" : 1,
        "Repair" : "Y",
        "Section" : "Grounds"
    ]
]


var newarr = [[String:String]]()
for dict in myarr {
    var newdict = [String:String]()
    for (key, value) in dict {
        newdict[key] = "\(value)"
    }
    newarr.append(newdict)
}
print(newarr)

输出：

[[“Level”：“2”，“Area”：“”，“Good”：“ - ”，“Link”：“＆lt; null＆gt;”，“修复”：“ - ”，“照片” ：“ - ”，“Section”：“Others”]，[“Level”：“2”，“Area”：“”，“Good”：“N”，“Link”：“http://someurl”， “修复”：“Y”，“照片”：“1”，“部分”：“理由”]]

Answer 3

您可以使用以下代码创建新词典：

var newArray:[[String: String]] = []
for data in myarr {
    var dict: [String: String] = [:]
    for (key, value) in data {
        let strData = String(describing: value)
        dict[key] = strData
    }
    newArray.append(dict)
}

在Swift中将任何字典数组转换为String
