将类型从字符串转换为字符串数组

Question

我想从我的应用程序中删除计划通知，为此我需要String数组来删除待处理的通知。我有这种类型的字符串，而不是从fbdb数据库返回String的数组，但是我想要数组

 ["01D94B0E-F1AB-421E-9EC3-4A78F0211ED8",
 "76E16E51-CB59-4D3F-939E-4D492FFB22BE",
 "97696EBD-252F-4A12-962E-995EF306B557",
 "84EB98BB-14EB-4D19-83F6-798DCF75E3CD",
 "B55621AE-B124-4767-8D6E-C728598E5279"]

我有此格式的数组，该怎么办？我知道这是初学者的问题，希望你们能帮忙

Answer 1

let str = """["01D94B0E-F1AB-421E-9EC3-4A78F0211ED8", "76E16E51-CB59-4D3F-939E-4D492FFB22BE", "97696EBD-252F-4A12-962E-995EF306B557", "84EB98BB-14EB-4D19-83F6-798DCF75E3CD", "B55621AE-B124-4767-8D6E-C728598E5279"]"""
let ids = try? JSONSerialization.jsonObject(with: Data(str.utf8)) as? [String] ?? []

您可以使用默认的JSONDecoder ...

import Foundation

var stringToData: Data? = "[\"01D94B0E-F1AB-421E-9EC3-4A78F0211ED8\", \"76E16E51-CB59-4D3F-939E-4D492FFB22BE\", \"97696EBD-252F-4A12-962E-995EF306B557\", \"84EB98BB-14EB-4D19-83F6-798DCF75E3CD\", \"B55621AE-B124-4767-8D6E-C728598E5279\"]".data(using: .utf8)

let decoded = try JSONDecoder().decode(Array<String>.self, from: stringToData!)
print(decoded)

输出：

[“ 01D94B0E-F1AB-421E-9EC3-4A78F0211ED8”，“ 76E16E51-CB59-4D3F-939E-4D492FFB22BE”，“ 97696EBD-252F-4A12-962E-995EF306B557”，“ 84EB98BB-14EB-4D19-83F6-798DCF75 ”，“ B55621AE-B124-4767-8D6E-C728598E5279”]

您可以尝试

let str = """ 
["1","2","3"]
"""
let res = str.dropFirst(1).dropLast(1)
let arr = res.components(separatedBy: ",").map { $0.replacingOccurrences(of: "\"", with: "") }
