如何将一个数组保存到UserDefaults，然后检索该数组并打印

Question

这是我的代码。这似乎是一个错误。任何人都可以请帮忙。

class PopUpVC: UIViewController { 
    var myArray1 = ["1","2","3"] 
    var myArray2 = [String]() 
    UserDefaults.standard.set(myArray1, forKey: "array") 

    override func viewDidLoad() { 
    super.viewDidLoad() 
    self.myArray2 = (UserDefaults.standard.string(forKey: "array") as? [String])! 
    print(self.myArray) 
    }

class PopUpVC: UIViewController { 
    var myArray1 = ["1","2","3"] 
    var myArray2 = [String]() 

override func viewDidLoad() { 
     super.viewDidLoad() 
     UserDefaults.standard.set(myArray1, forKey: "array") 
     self.myArray2 = UserDefaults.standard.stringArray(forKey: "array")! 
     print(self.myArray2) 
}
