在[String:String]中转换[(key:String，value:String)] [英] convert [(key: String, value: String)] in [String:String]

问题描述

我想在[String:String]中转换[(键:字符串，值:字符串)]可以吗?如果是的话，我怎么做?谢谢

I want convert [(key: String, value: String)] in [String:String] is possible to do ? If yes how i make ? thanks

var KeyValuePair: [(key: String, value: String)] = [(key: "2017 01 04", value: "143.65"), (key: "2017 01 05", value: "140.78"), (key: "2017 01 06", value: "150.23")]

在

var dictionary: [String:String] =  ["2017 01 04":"143.65", "2017 01 05":"140.78", "2017 01 06":"150.23"]

推荐答案

您只需要遍历元组数组，并使用元组的值设置字典的键值对.

You just need to iterate through the array of tuples and set the key-value pair of your dictionary with the values of the tuple.

var keyValuePairs: [(key: String, value: String)] = [(key: "2017 01 04", value: "143.65"), (key: "2017 01 05", value: "140.78"), (key: "2017 01 06", value: "150.23")]

var dictionary = [String:String]()
keyValuePairs.forEach{
    dictionary[$0.0] = $0.1
    //since you have named tuples, you could also write dictionary[$0.key] = $0.value
}
print(dictionary)

请确保您遵循Swift命名约定，该约定对于变量名来说是小写字母.

Please make sure you conform to the Swift naming convention, which is lower-camelcase for variable names.
