Error with integer

Question

This is my code to disable buttons on a view controller if an integer is below a certain amount.

if (plancnt.value(forKey: "plancnt") != nil){
        plancnt.set(1, forKey: "plancnt")
    }
if (plancnt.integer(forKey: "plancnt") <= 1) {
        two.isEnabled = false

    }

However when i write

plancnt.set(20, forKey: "plancnt")
    plancnt.synchronize()

all of the button except button one are disabled. Im not sure if my greater than/less than signs are wrong or something else, please help.

@OrenEdrich Use an Array! Read up the Swift language guide. If you have questions, come back here and we can help :) — Alexander, Jan 06 '17 at 07:06
You should make an array to store all these numbers, and simply loop over from 0 to `plancnt.integer(forKey: "plancnt")`, setting the `isEnabled` false — Alexander, Jan 06 '17 at 07:15
@MitchWheat Using array for over 20 item will not work. Xcode will get stuck on indexing stackoverflow.com/questions/13831559/xcode-stuck-on-indexing — Oren Edrich, Jan 06 '17 at 09:41

Because all you did were to disable buttons, you never reenable them when plancnt changes. And your code gives me a headache. Try something like this:

if plancnt.value(forKey: "plancnt") == nil {
    plancnt.set(1, forKey: "plancnt")
}

let buttons = [one, two, three, ..., twenty]
let cnt = plancnt.integer(forKey: "plancnt")

for i in 0..<buttons.count {
    buttons[i].isEnabled = i < cnt
}

This could not work, beacuse a twenty item array cause Xcode to crash. I tried this out my self and it was unable to index. http://stackoverflow.com/questions/13831559/xcode-stuck-on-indexing – Oren Edrich Jan 06 '17 at 09:37
1) Press `Cmd + Shift + K` to clean your project and rebuild 2) If that still doesn't work, give Xcode a hint of what's in your array: `let buttons: [UIButton] = [one, two, ...]` – Code Different Jan 06 '17 at 14:29

Do something like this:

var buttons = [one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen,sixteen,seventeen,eighteen,nineteen,twenty]
        let i: Int = plancnt.value(forKey: "plancnt")
        for index in i..<buttons.count {
            print("\(index)")
            buttons[index].isEnabled = false
        }

In the starboard file unclick the "enabled" button and type this under the viewdidload

if (plancnt.integer(forKey: "plancnt") >= 1) {
        one.isEnabled = true
    }
    if (plancnt.integer(forKey: "plancnt") >= 2) {
        two.isEnabled = true
    }
    if (plancnt.integer(forKey: "plancnt") >= 3) {
        three.isEnabled = true
    }
    if (plancnt.integer(forKey: "plancnt") >= 4) {
