如何在Swift中用NSUserDefaults将自定义对象保存到数组中？

class CustomObject: NSObject, NSCoding {
    var name: String
    var age: Int
    
    init(name: String, age: Int) {
        self.name = name
        self.age = age
    }
    
    func encode(with aCoder: NSCoder) {
        aCoder.encode(name, forKey: "name")
        aCoder.encode(age, forKey: "age")
    }
    
    required init?(coder aDecoder: NSCoder) {
        name = aDecoder.decodeObject(forKey: "name") as? String ?? ""
        age = aDecoder.decodeInteger(forKey: "age")
    }
}

var customObjects: [CustomObject] = []

let userDefaults = UserDefaults.standard

// 将自定义对象编码为Data类型
let encodedData = NSKeyedArchiver.archivedData(withRootObject: customObject)

// 将Data类型存储到UserDefaults中
userDefaults.set(encodedData, forKey: "customObjects")

if let decodedData = userDefaults.object(forKey: "customObjects") as? Data {
    if let decodedObjects = NSKeyedUnarchiver.unarchiveObject(with: decodedData) as? [CustomObject] {
        customObjects = decodedObjects
    }
}
