1.根据用户回答计算得分
ViewController.swift:
import UIKit
class ViewController: UIViewController {
var questionIndex = 0
var score = 0
@IBOutlet weak var questionLabel: UILabel!
@IBOutlet weak var scoreLabel: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
questionLabel.text = queastions[0].text
}
@IBAction func answerPressed(_ sender: UIButton) {
checkAnswer(sender.tag)
questionIndex += 1
nextQuestion()
}
func nextQuestion(){
if questionIndex <= 12{
questionLabel.text = queastions[questionIndex].text
}else{
questionIndex = 0
let alert = UIAlertController(title: "漂亮！", message: "您已经完成了所有问题，要再来一遍吗？", preferredStyle: .alert)
let action = UIAlertAction(title: "再来一遍", style: .default, handler: { _ in
self.questionLabel.text = queastions[0].text
})
alert.addAction(action)
//
present(alert, animated: true)
}
}
func checkAnswer(_ tag: Int){
if tag == 1 {
if queastions[questionIndex].answer == true{
print("huidazhengque")
score += 1
scoreLabel.text = "总得分：\(score)"
}else{
print("huidacuowu")
}
}else{
if queastions[questionIndex].answer == true{
print("huidacuowu")
}else{
print("huidazhengque")
score += 1
scoreLabel.text = "总得分：\(score)" }
} }
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
2.显示题目序号
ViewController.swift:
import UIKit
class ViewController: UIViewController {
var questionIndex = 0
var score = 0
@IBOutlet weak var questionLabel: UILabel!
@IBOutlet weak var scoreLabel: UILabel!
@IBOutlet weak var progressLable: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
questionLabel.text = queastions[0].text
}
@IBAction func answerPressed(_ sender: UIButton) {
checkAnswer(sender.tag)
questionIndex += 1
nextQuestion()
progressLable.text = "\(questionIndex + 1) / 13"
}
func nextQuestion(){
if questionIndex <= 12{
questionLabel.text = queastions[questionIndex].text
}else{
questionIndex = 0
let alert = UIAlertController(title: "漂亮！", message: "您已经完成了所有问题，要再来一遍吗？", preferredStyle: .alert)
let action = UIAlertAction(title: "再来一遍", style: .default, handler: { _ in
self.questionLabel.text = queastions[0].text
})
alert.addAction(action)
//
present(alert, animated: true)
}
}
func checkAnswer(_ tag: Int){
if tag == 1 {
if queastions[questionIndex].answer == true{
print("huidazhengque")
score += 1
scoreLabel.text = "总得分：\(score)"
}else{
print("huidacuowu")
}
}else{
if queastions[questionIndex].answer == true{
print("huidacuowu")
}else{
print("huidazhengque")
score += 1
scoreLabel.text = "总得分：\(score)" }
} }
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
3.为屏幕进度条更改约束
将1：13的宽度约束拖入ViewController。
因为progressBarView是只读，所以要根据屏幕宽度计算出1/13的宽度，然后加到Constant中。
ViewController.swift:
import UIKit
class ViewController: UIViewController {
var questionIndex = 0
var score = 0
@IBOutlet weak var questionLabel: UILabel!
@IBOutlet weak var scoreLabel: UILabel!
@IBOutlet weak var progressLable: UILabel!
@IBOutlet weak var progressBarViewWidth: NSLayoutConstraint!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
questionLabel.text = queastions[0].text
}
@IBAction func answerPressed(_ sender: UIButton) {
checkAnswer(sender.tag)
questionIndex += 1
nextQuestion()
progressLable.text = "\(questionIndex + 1) / 13"
progressBarViewWidth.constant = (view.frame.width / 13) * CGFloat(questionIndex)
}
func nextQuestion(){
if questionIndex <= 12{
questionLabel.text = queastions[questionIndex].text
}else{
questionIndex = 0
let alert = UIAlertController(title: "漂亮！", message: "您已经完成了所有问题，要再来一遍吗？", preferredStyle: .alert)
let action = UIAlertAction(title: "再来一遍", style: .default, handler: { _ in
self.questionLabel.text = queastions[0].text
self.scoreLabel.text = "总得分：0"
})
alert.addAction(action)
//
present(alert, animated: true)
}
}
func checkAnswer(_ tag: Int){
if tag == 1 {
if queastions[questionIndex].answer {
print("huidazhengque")
score += 1
scoreLabel.text = "总得分：\(score)"
}else{
print("huidacuowu")
}
}else{
if queastions[questionIndex].answer {
print("huidacuowu")
}else{
print("huidazhengque")
score += 1
scoreLabel.text = "总得分：\(score)" }
} }
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
4.制作弹窗
https://github.com/relatedcode/ProgressHUD
将gitHub上拉的swift文件拖到项目中去。
在ViewController中调用这个swift中的方法。
import UIKit
class ViewController: UIViewController {
var questionIndex = 0
var score = 0
@IBOutlet weak var questionLabel: UILabel!
@IBOutlet weak var scoreLabel: UILabel!
@IBOutlet weak var progressLable: UILabel!
@IBOutlet weak var progressBarViewWidth: NSLayoutConstraint!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
questionLabel.text = queastions[0].text
}
@IBAction func answerPressed(_ sender: UIButton) {
checkAnswer(sender.tag)
questionIndex += 1
nextQuestion()
progressLable.text = "\(questionIndex + 1) / 13"
progressBarViewWidth.constant = (view.frame.width / 13) * CGFloat(questionIndex)
}
func nextQuestion(){
if questionIndex <= 12{
questionLabel.text = queastions[questionIndex].text
}else{
questionIndex = 0
let alert = UIAlertController(title: "漂亮！", message: "您已经完成了所有问题，要再来一遍吗？", preferredStyle: .alert)
let action = UIAlertAction(title: "再来一遍", style: .default, handler: { _ in
self.questionLabel.text = queastions[0].text
self.scoreLabel.text = "总得分：0"
})
alert.addAction(action)
//
present(alert, animated: true)
}
}
func checkAnswer(_ tag: Int){
if tag == 1 {
if queastions[questionIndex].answer {
ProgressHUD.showSucceed("答对了")
score += 1
scoreLabel.text = "总得分：\(score)"
}else{
ProgressHUD.showError("答错了")
}
}else{
if queastions[questionIndex].answer {
ProgressHUD.showError("答错了")
}else{
ProgressHUD.showSucceed("答对了")
score += 1
scoreLabel.text = "总得分：\(score)" }
} }
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
