Quickest way to check multiple bools and changing image depending on that bool - swift

Question

I have multiple achievements that the user can achieve during the game. When the user goes to the achievement VC, he should see an image when the achievement is accomplished.
I am now using this code in the viewDidLoad function:
if unlockedAchievement1 == true
{
achievement1Text.textColor = UIColor.greenColor()
achievement1Image.image = UIImage(named: "achievement1Unlocked")
}
if unlockedAchievement2 == true
{
achievement2Text.textColor = UIColor.greenColor()
achievement2Image.image = UIImage(named: "achievement2Unlocked")
}
This would work, but it takes a lot of time to copy paste this overtime. How can I shorten this? Should I make a class? I read about for in loops, but I did not quite understood that. Any help is welcome!

Answer 1

I feel like I have seen this before. But anyway...
//use array of bools. First declare as empty array.
//Use Core data to achieve saving the Booleans if you need to.
let achievements:[Bool] = []
let achievementsImage:[UIImage] = []
let achievementsText:[UITextView] = []
func viewDidLoad() {
//Say you have 5 achievements.
for index in 0 ..< 5 {
achievements.append(false)
achievementsImage.append(UIImage(named: "achievementLocked"))
achievementText.append(UITextView())
//Then you can edit it, such as.
achievementText[index].frame = CGRect(0, 0, 100, 100)
achievementText[index].text = "AwesomeSauce"
self.view.addSubview(achievementText[index])
achievementText[index].textColor = UIColor.blackColor()
}
}
//Call this function and it will run through your achievements and determine what needs to be changed
func someFunction() {
for index in 0 ..< achievements.count {
if(achievements[index]) {
achievements[index] = true
achievementsImage[index] = UIImage(named: String(format: "achievement%iUnlocked", index))
achievementsText[index].textColor = UIColor.greenColor
}
}
}

I'd recommend making your unlockedAchievement1, unlockedAchievement2, etc. objects tuples, with the first value being the original Bool, and the second value being the image name. You'd use this code:
// First create your data array
var achievements = [(Bool, String)]()
// Then you can make your achievements.
// Initially, they're all unearned, so the Bool is false.
let achievement1 = (false, "achievement1UnlockedImageName")
achievements.append(achievement1)
let achievement2 = (false, "achievement2UnlockedImageName")
achievements.append(achievement2)
// Now that you have your finished data array, you can use a simple for-loop to iterate.
// Create a new array to hold the images you'll want to show.
var imagesToShow = [String]()
for achievement in achievements {
if achievement.0 == true {
imagesToShow.append(achievement.1)
}
}
