Okay, I give up.
I am making a Flash card game where the app will randomize two numbers, then the user would enter the answer. The app will then tell the user if he/she is correct. But I cannot seem to figure out how to get it to add two numbers and check if the user's correct or not.
Any help is greatly appreciated!
Here's the code:
import UIKit
import AVFoundation
import Foundation
class YouSolveIt: UIViewController {
@IBOutlet var topProblem: UILabel!
@IBOutlet var botProblem: UILabel!
@IBOutlet var youAnswer: UITextField!
@IBOutlet var actualCard: UIImageView!
let speakit = AVSpeechSynthesizer()
var problem1 = Int(0)
var problem2 = Int(0)
var answer = 0
var ranA = 0
var ranB = 0
override func viewDidLoad() {
super.viewDidLoad()
// Load Flash Card image:
actualCard.image = UIImage(named: "FlashCard")
solveitproblem()
}
func solveitproblem()
{
let ranA = Int(arc4random_uniform(UInt32(9)))
let ranB = Int(arc4random_uniform(UInt32(9)))
topProblem.text = String(ranA)
botProblem.text = String(ranB)
youAnswer.text = String(answer)
let speakProblem = AVSpeechUtterance(string: "What is \(topProblem.text! + ", plus ," + botProblem.text!)")
speakit.speak(speakProblem)
}
@IBAction func btncheckAnswer(_ sender: Any)
{
if (ranA) + (ranB) == answer
{
correctAnswer()
}
else {
wrongAnswer()
}
}
func correctAnswer()
{
let right = [1,2,3,4,5]
let randomIndex = Int(arc4random_uniform(UInt32(right.count)))
switch(randomIndex)
{
case 1:
let speakRight = AVSpeechUtterance(string: "That is correct")
speakit.speak(speakRight)
youAnswer.text = ""
solveitproblem()
case 2:
let speakRight = AVSpeechUtterance(string: "You're right!")
speakit.speak(speakRight)
youAnswer.text = ""
solveitproblem()
case 3:
let speakRight = AVSpeechUtterance(string: "Correct! Let's try.")
speakit.speak(speakRight)
youAnswer.text = ""
solveitproblem()
case 4:
let speakRight = AVSpeechUtterance(string: "You are right! Next Try.")
speakit.speak(speakRight)
youAnswer.text = ""
solveitproblem()
case 5:
let speakRight = AVSpeechUtterance(string: "Great answer!")
speakit.speak(speakRight)
youAnswer.text = ""
solveitproblem()
default:
let speakRight = AVSpeechUtterance(string: "Very good!")
speakit.speak(speakRight)
youAnswer.text = ""
solveitproblem()
}
}
func wrongAnswer()
{
let wrong = [1,2,3,4,5]
let randomIndex = Int(arc4random_uniform(UInt32(wrong.count)))
switch(randomIndex)
{
case 1:
let speakRight = AVSpeechUtterance(string: "That is wrong")
speakit.speak(speakRight)
case 2:
let speakRight = AVSpeechUtterance(string: "You're wrong, please try again.")
speakit.speak(speakRight)
case 3:
let speakRight = AVSpeechUtterance(string: "No, that's not it. Please try again.")
speakit.speak(speakRight)
case 4:
let speakRight = AVSpeechUtterance(string: "No")
speakit.speak(speakRight)
default:
let speakRight = AVSpeechUtterance(string: "I'm sorry, no. Please try again.")
speakit.speak(speakRight)
}
}
}
