本文介绍了如何使用swift解析字典中的Any的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我不是如何解析类型为的字典值.
我能够读取为字符串的键,其值是Any类型,并且在给定键的示例values
以下
I'm not how do it parse a dictionary value which is of type .
I'm able to read the key which is string and value is type of Any and has below sample values
for given key
▿ 1 element
▿ 0 : 4 elements
▿ 0 : 2 elements
- key : nativeName
- value : Shqip
▿ 1 : 2 elements
- key : iso639_2
- value : sqi
▿ 2 : 2 elements
- key : name
- value : Albanian
▿ 3 : 2 elements
- key : iso639_1
- value : sq
从上面,我只需要提取名称":爱沙尼亚语" 疲倦的循环使用swift无效.
From above, I only need to extract "name":"Estonian" Tired looping it did not work using swift.
代码:
f(key == "languages"){
var nameArray = value as! NSArray
for str in nameArray{
print(str)
}
}
完成JSON响应

推荐答案
请勿使用Any.不要使用NSArray.不要使用NSDictionary.这是斯威夫特!使用Swift类型和JSON的Swift解码.
Do not use Any. Do not use NSArray. Do not use NSDictionary. This is Swift! Use Swift types and Swift decoding of the JSON.
以下是您作为数据对象的JSON:
Here is your JSON as a Data object:
[
{
"name":"Estonia",
"topLevelDomain":[".ee"],
"alpha2Code":"EE",
"alpha3Code":"EST",
"callingCodes":["372"],
"capital":"Tallinn",
"altSpellings":["EE","Eesti","Republic of Estonia","Eesti Vabariik"],
"region":"Europe",
"subregion":"Northern Europe",
"population":1315944,
"latlng":[59.0,26.0],
"demonym":"Estonian",
"area":45227.0,
"gini":36.0,
"timezones":["UTC+02:00"],
"borders":["LVA","RUS"],
"nativeName":"Eesti",
"numericCode":"233",
"currencies":[{"code":"EUR","name":"Euro","symbol":"€"}],
"languages":[
{
"iso639_1":"et",
"iso639_2":"est",
"name":"Estonian",
"nativeName":"eesti"
}
],
"translations":
{
"de":"Estland",
"es":"Estonia",
"fr":"Estonie",
"ja":"エストニア",
"it":"Estonia",
"br":"Estônia",
"pt":"Estónia",
"nl":"Estland",
"hr":"Estonija",
"fa":"استونی"
},
"flag":"https://restcountries.eu/data/est.svg",
"regionalBlocs":[
{
"acronym":"EU",
"name":"European Union",
"otherAcronyms":[],
"otherNames":[]
}
],
"cioc":"EST"
}
]
"""
let data = json.data(using: .utf8)!
以下是从中提取语言名称的方法:
Here is how to extract the language name from it:
struct Language : Decodable {
let name : String
}
struct Entry : Decodable {
let languages : [Language]
}
let entries = try! JSONDecoder().decode([Entry].self, from: data)
let lang = entries[0].languages[0].name // Estonian
