Question

我想制作这种类型的结果：

{"":[["someId","someName"]]}

我想这样做：

var fields:[AnyObject] = [AnyObject]()

for someId:String in Preferences.getAllIds(){
        let someName = Preferences.getAllNames(someId)
        let value = String(format: "%@,%@", someId,someName)
        var field:[String] = [String]()
        field.append(value)
        fields.append(field as AnyObject)
    }
let dict = ["": fields]

我得到的输出是：

{"":[["012345,test_name"]]}

如您所见：在 012345 之前和之后 test_name

之前有双倍数据

＆＃34; 012345，TEST_NAME＆＃34;

但是我想在字符串的两边添加开头和结尾。

赞：＆＃34; 012345＆＃34;，＆＃34; test_name＆＃34;

我试图通过这个技巧获得所需的输出，但不幸的是失败了（不知道为什么这不起作用）...... :(

value1 = value.replacingOccurrences(of: ",", with: "\",\"")

你需要像这样定义它的数组，希望它会帮助你

;WITH CTE AS(
         SELECT myId,
         ROW_NUMBER()OVER(PARTITION BY col1 ORDER BY col1) AS RowN
   FROM dbo.Table1
)
DELETE FROM CTE 
WHERE RowN > 1

如果你有静态值然后你可以像这样制作数组

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

for someId:String in Preferences.getAllIds(){
    let someName = Preferences.getAllNames(someId)
    var arrValue : [String] = [String]()
    arrValue.append(someId)
    arrValue.append(someName)// ["someid","somename"]
    fields.append(arrValue as [String]) // [["someid","somename"]]
}
   let dict = ["": fields] // {"" : [["someid","somename"]]}
