所以我目前正在读取这个 txt 文件：

我试图只打印出命令行中的名称（基本上只有大写字母），没有重复。例如：

ATLAS_CENTAUR
DELTA
SCOUT
PEGASUS …

我目前在标签无法自动读取 3 个文本字段值的添加时遇到问题，而无需按钮功能操作。因此，我只希望我的文本字段是一个 Int 输入。下面附上一个屏幕截图，以供更好地参考。感谢那些能帮助我解决这个问题的人。谢谢！

视图控制器

import UIKit

class TryingoutController: UIViewController {
    @IBOutlet var impact: UITextField!
    @IBOutlet var rigour: UITextField!
    @IBOutlet var response: UITextField!
    @IBOutlet var total: UILabel!

快速提问，有人知道如何去除视频顶部和底部的黑条吗？我刚开始使用 AVPlayer，我只是在这里和那里删除代码以尝试删除黑色图层。感谢那些可以帮助我的人，谢谢！

视图控制器

import UIKit
import AVKit
import AVFoundation
private var looper: AVPlayerLooper?

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        let path = Bundle.main.path(forResource: "Innie-Kiss", ofType:"mp4")
        let player = AVQueuePlayer(url: URL(fileURLWithPath: path!))
        looper = AVPlayerLooper(player: player, templateItem: AVPlayerItem(asset: AVAsset(url: URL(fileURLWithPath: path!))))
        let controller = AVPlayerViewController()
        controller.player = player
        let screenSize = UIScreen.main.bounds.size
        let videoFrame = CGRect(x: 0, y: 200, width: screenSize.width, height: (screenSize.height - 130) / 2)
        controller.view.frame = videoFrame
        self.view.addSubview(controller.view)
        player.play()
    }

}

我现在正在循环我的mp4视频,没有播放控件,有点像gif但有声音.但我不知道为什么当我转到下一个视图控制器时,视频仍在播放.有人知道解决这个问题的最简单方法吗？

视图控制器

import UIKit
import AVKit
import AVFoundation
fileprivate var playerObserver: Any?


class ScoreController: UIViewController {
    @IBOutlet var label: UILabel!

    override func viewDidLoad() {
        super.viewDidLoad()


        let returnValue: Int = UserDefaults.standard.integer(forKey: "userScore")
        label.text = "Your Score: \(returnValue)/30"

        do {
            try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
            let path = Bundle.main.path(forResource: "Innie-Kiss", ofType:"mp4")
            let player = AVPlayer(url: URL(fileURLWithPath: path!))
            let resetPlayer = {
                player.seek(to: kCMTimeZero)
                player.play()
            }
            playerObserver = NotificationCenter.default.addObserver(forName: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: player.currentItem, queue: nil) { notification in resetPlayer() }
            let controller = AVPlayerViewController()
            controller.player = player …

长话短说,我的segue无法执行到我已创建的下一个控制器.很多帮助将不胜感激.

    override func viewDidLoad() {
        super.viewDidLoad()


        var returnValue: Int = UserDefaults.standard.integer(forKey: "quiz1Validation")
        if (returnValue == 1)
        {
            performSegue(withIdentifier: "completed", sender: self)
        }
        else {
        var returnValue: Int = UserDefaults.standard.integer(forKey: "userScore")
        scorelabel.text = "Score:\(returnValue)"
        RandomQuestions()
    }

}
