作業：⭐️ 猜數字 App & 1A2B
Published in
11 min readSep 20, 2022
目的: 學習產生隨機數字，數字和字串之間的轉換。
左邊是猜數字，右邊是1A2B，我覺得我真的沒有什麼美術天份，然後這是兩個專案，因為我還不知道怎麼他們弄成一個，但至少功能還算正常🤔
猜數字操作畫面：
1A2B操作畫面：
猜數字算是比較簡單的，1A2B比較難，寫起來感覺亂七八糟的，有種缺什麼補什麼的感覺，全部寫完才又再重新看一次，並加上註解，才覺得有好點。
猜數字程式碼：
import UIKitclass ViewController: UIViewController {@IBOutlet weak var lifeLable: UILabel!
@IBOutlet weak var guessNumberTextField: UITextField!
@IBOutlet weak var showResult: UILabel!
@IBOutlet weak var GO: UIButton!
var answer = Int.random(in: 1...99)
var min = 0
var max = 100
var life = 6
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
showResult.text = "請輸入\(min)~\(max)之間的數字"
lifeLable.text = "\(life)"
}
@IBAction func goBtn(_ sender: Any) {
let guessNumber = Int(guessNumberTextField.text!)
if guessNumber != nil{
if guessNumber! == answer{
showResult.text = "太強了！"
GO.isEnabled = false
guessNumberTextField.isEnabled = false
}else if guessNumber! < answer{
min = guessNumber!
showResult.text = "太小了，再試試，請輸入\(min)~\(max)之間的數字"
guessNumberTextField.text = ""
}else{
max = guessNumber!
showResult.text = "太大了，再試試，請輸入\(min)~\(max)之間的數字"
guessNumberTextField.text = ""
}
life -= 1
if life == 0, guessNumber! != answer{
lifeLable.text = "\(life)"
showResult.text = "芭比Ｑ了～Game Over～"
guessNumberTextField.isEnabled = false
GO.isEnabled = false
}else{
lifeLable.text = "\(life)"
}
}
}
@IBAction func replayBtn(_ sender: Any) {
guessNumberTextField.isEnabled = true
GO.isEnabled = true
life = 6
lifeLable.text = "\(life)"
answer = Int.random(in: 1...99)
showResult.text = ""
guessNumberTextField.text = ""
min = 0
max = 100
showResult.text = "請輸入\(min)~\(max)之間的數字"
}
}
1A2程式碼：

super.viewDidLoad()
// Do any additional setup after loading the view.
newGame()
