Save an array of colors to User Defaults - iOS Swift 2.3
1
I am wondering how to save an array of UIColors to user default.
I have the following code to save a single UIColor to user defaults, does anyone know how to modify this to allow me to store arrays of UIColor in NS User Defaults?
extension NSUserDefaults {
func colorForKey(key: String) -> UIColor? {
var color: UIColor?
if let colorData = dataForKey(key) {
color = NSKeyedUnarchiver.unarchiveObjectWithData(colorData) as? UIColor
}
return color
}
func setColor(color: UIColor?, forKey key: String) {
var colorData: NSData?
if let color = color {
colorData = NSKeyedArchiver.archivedDataWithRootObject(color)
}
setObject(colorData, forKey: key)
}
}- I am using Swift 2.3

You can do it in following way
let colors = [UIColor.whiteColor(), UIColor.greenColor()] // Array of colors
NSUserDefaults.standardUserDefaults().setObject(NSKeyedArchiver.archivedDataWithRootObject(colors), forKey: "ColorsKey") //For saving in NSUserDefaults
//For retrieving use following
let decodedColorsData = NSUserDefaults.standardUserDefaults().objectForKey("ColorsKey") as! NSData
let colorsArray = (NSKeyedUnarchiver.unarchiveObjectWithData(decodedColorsData) as! NSArray) as Array

Swift 4.2: Saving and loading colours / colours to user defaults
note: the load from defaults works but contains a deprecated item which does not yet have a good worked example to replace it.
let colorToSetAsDefault : UIColor = view.backgroundColor!
do
{
let data : NSData = try NSKeyedArchiver.archivedData(withRootObject: colorToSetAsDefault,requiringSecureCoding: false) as NSData
UserDefaults.standard.set(data, forKey: "userHeadingColor") // your key in quotes
UserDefaults.standard.synchronize()
} // end of do
catch
{
print("Couldn't save color")
} // end of catch
// load the color back as a test to make sure the save has worked
if let colorObject = UserDefaults.standard.object(forKey: "userHeadingColor")
{
let colorData = colorObject as! NSData
let color = NSKeyedUnarchiver.unarchiveObject(with: colorData as Data) as? UIColor
// replace with unarchivedObjectOfClass:fromData:error:
self.testDefaultsView.backgroundColor = color
}
else
{
}
