如何将这个.plist文件直接解析为Swift中的对象

Question

我有一个covid.plist文件，如下所示，并试图找出如何解析到对象并读取这些数据？

新冠肺炎.plist

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>key1</key>
<string>value for key1</string>
<key> key2</key>
<string>valua for key1</string>
<key>Covid1</key>
<dict>
<key>covid1_key</key>
<string>covid1_value</string>
</dict>
<key>Covid2</key>
<dict>
<key>covid2_key</key>
<string>covid2_value</string>
</dict>
</dict>
</plist>

你的代码似乎被感染了，所以我戴上口罩，洗手，与mac保持一点距离：(无论如何，我认为PropertyListDecoder可以用于将plist文件直接解码到你的对象，用于你的情况

struct Covid1:Codable {
var covid1_key:String?
private enum CodingKeys : String, CodingKey {
case covid2_key = "covid1_key"
}
}
struct Covid2:Codable {
var covid2_key:String?
private enum CodingKeys : String, CodingKey {
case covid2_key = "covid2_key"
}    
}
struct PlistConfiguration:Codable {
var key1:String?
var covid1: Covid1?
var covid2: Covid2?

private enum CodingKeys : String, CodingKey {
case key1 = "key1"
case covid1 = "Covid1"
case covid2 = "Covid2"
}
}

并使用此功能进行操作：

func parseCovid() -> PlistConfiguration {
let url = Bundle.main.url(forResource: "covid", withExtension: "plist")!
let data = try! Data(contentsOf: url)
let decoder = PropertyListDecoder()
return try! decoder.decode(PlistConfiguration.self, from: data)
}
