arrays - 我收到错误 = 无法将类型 'String?' 的值分配给类型 '[String]' 我到处都看了，但似乎找不到答案

Question

import UIKit

class FirstViewController: UIViewController
 {

    @IBOutlet var Dishname: UILabel!

    @IBOutlet var TEXT: UITextField!

    @IBOutlet var recipy: UIView!



    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

        let secondVC: SecondViewController = segue.destinationViewController as! SecondViewController


        secondVC.items = TEXT.text! as? String    //Error

// Cannot assign value of type 'String?' to type '[String]'

    }

Answer 1

SecondViewController 中的 items 变量是字符串数组，[String] 类型，您尝试为其分配一个字符串，而不是插入或追加到其中。
