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

I had a tuple with 3 values.

The following code was used for saving the tuple. Basically, I created a string from tuple (with components separated by a comma).

let defaultsLoad = NSUserDefaults.standardUserDefaults()
if appSingleton.runwayDestShared != nil
{
   // Creating a String from the tuple
   let runwayDestString = appSingleton.runwayDestShared!.0 + "," + appSingleton.runwayDestShared!.1  + "," + appSingleton.runwayDestShared!.2
   defaultsLoad.setObject(runwayDestString, forKey: "RunwayDest")
}

To retrieve the tuple, I retrieved the string, broke it into array and used the array to re-create a tuple.

let runwayDestString = defaultsLoad.stringForKey("RunwayDest")
if let runwayDestString = runwayDestString
{
    let runwayDestArray = runwayDestString.componentsSeparatedByString(",")
    appSingleton.runwayDestShared = (runwayDestArray[0],runwayDestArray[1],runwayDestArray[2])
}
