ios - 如何制作一个自动调整的UiTextField Frame

Question

我正在尝试制作一个可根据屏幕尺寸和方向调整大小的 UiTextField 框架，但我没有取得太大成功。 (框架如 uitextfieldname.frame(x:,y:,width:,height:) 这是我的代码:

import SpriteKit
import GameplayKit
import UIKit

class GameScene: SKScene {

override func didMove(to view: SKView) {

    // Get label node from scene and store it for use later

    let animateList = SKAction.sequence([SKAction.fadeIn(withDuration: 1.0), SKAction.wait(forDuration: 2.0), SKAction.fadeOut(withDuration: 1.0)])

    let startScreen = SKLabelNode(fontNamed: "Helvetica Neue UltraLight")
    startScreen.text = "Welcome"
    startScreen.fontSize = 100.0
    startScreen.fontColor = SKColor.white
    startScreen.position = CGPoint(x: self.frame.midX, y: self.frame.midY)
    self.addChild(startScreen)
    startScreen.alpha = 0.0



    startScreen.run(animateList)

    _ = Timer.scheduledTimer(withTimeInterval: 5.0, repeats: false) { _ in
        startScreen.text = "I don't belive we have met before"

        startScreen.run(animateList)

    }

    _ = Timer.scheduledTimer(withTimeInterval: 10.0, repeats: false) { _ in
        startScreen.text = "What's your name?"

        startScreen.run(animateList)

    }

    _ = Timer.scheduledTimer(withTimeInterval: 15.0, repeats: false) { _ in
        let name = UITextField()
        //name.frame = CGRect(x: ,y: ,width: , height: )
    }
}

}

您需要使用自动布局约束固定前导、尾随、顶部和底部约束并设置numberofLines = 0以调整框架。
