Save a tuple in NSUserDefaults

Question

I\'m using a tuple to store something like this.

var accessLavels: (hasInventoryAccess: Bool, hasPayrolAccess: Bool)
accessLavels = (hasInventoryAccess: true         


        

Answer 1

You can store Bool, Float, Int, Object, Double or URL but not a Tuple. So you have two options, save two only hasPayrolAccess and hasPayrolAccess Bool values:

NSUserDefaults.standardUserDefaults().setBool(true, forKey: "hasInventoryAccess")
NSUserDefaults.standardUserDefaults().setBool(false, forKey: "hasPayrolAccess")
let hasInventoryAccess  = NSUserDefaults.standardUserDefaults().boolForKey("hasInventoryAccess")
println(hasInventoryAccess)

let hasPayrolAccess  = NSUserDefaults.standardUserDefaults().boolForKey("hasPayrolAccess")
println(hasPayrolAccess)

Or save it using an Array of Bool:

var accessLavels = [true,false]
println(accessLavels)
NSUserDefaults.standardUserDefaults().setValue(accessLavels, forKey: "accessLavels")
if let loadAccessLavels = NSUserDefaults.standardUserDefaults().arrayForKey("accessLavels") as? [Bool] {
    if let hasInventoryAccess = loadAccessLavels.first {
        println(hasInventoryAccess)
    }
    if let hasPayrolAccess = loadAccessLavels.last {
        println(hasPayrolAccess)
    }
}
