使用 Swift 将输入从 TextField 打印到 Xcode 中的标签 [英] Printing input from TextField to a Label in Xcode with Swift

问题描述

我正在开发一个简单的猜谜游戏应用程序，只是为了更好地使用 Swift 和 Xcode.我已经能够在 userInput 中输入并让它向控制台打印一条消息，但是当我尝试让它将我的输入打印到 usersGuess(这是一个标签)时，我无法弄清楚.

I'm working on a simple guessing game app, just to get more comfortable with Swift and Xcode. I have been able to input within userInput and get it to print a message to the console, however when I try to get it to print my input to usersGuess(which is a label), I can not figure it out.

这是我通过 Xcode 在单视图应用程序中的代码:

Here's my code within a single view application via Xcode:

import UIKit

class ViewController: UIViewController {
    @IBOutlet weak var correctAnswerLabel: UILabel!
    @IBOutlet weak var usersGuess: UILabel!

    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.
    }

    @IBAction func buttonPressed() {
        correctAnswerLabel.text = "Changes when the button is pressed."
    }

    @IBAction func userInput(sender: UITextField) {
        println("This is working")
    }


}

我确定这很简单，但我正在挠头哈哈.

I'm sure this is simple, but I am scratching my head lol.

推荐答案

@IBAction func userInput(sender: UITextField) {
    println("This is working")
    usersGuess.text = sender.text
}
