populate a button from coredata - core-data

Question

I’m spending lots of time trying to figure this out and getting no where.
I have an entity with a NSDate attribute, which successfully saves.
How on Earth do I fetch the NSDate from the store(year only section) and make it populate the text on a button.
so the button can be pressed later and taken to another View Controller/Table View Controller.
I have spent hours trying to figure this out, I’m totally stuck can’t find any examples.
Does anyone have the time to help with this please.
Using Swift
(hopefully I have formated this question correctly, bit of a noob here)
Thank you for looking
//year button
#IBAction func btnYear(sender: AnyObject) {
//APP DEL REFERANCE
var appdel: AppDelegate = (UIApplication.sharedApplication().delegate as AppDelegate)
var context: NSManagedObjectContext = appdel.managedObjectContext!
let ent = NSEntityDescription.entityForName("FilmInfo", inManagedObjectContext: context)!
// fetch request
var request = NSFetchRequest(entityName: "FilmInfo")
request.returnsObjectsAsFaults = false

Answer 1

First, get the date from your data.
object.date
Then, format it so you can display it on the button.
var formatter = NSDateFormatter()
formatter.dateStyle= .ShortStyle
let buttonTitle = formatter.stringFromDate(object.date)
Finally assign the title to the button
button.setTitle(buttonTitle, forState: .Normal)
To get to the object in the first place, fetch it. Don't forget to execute your fetch request.
var request = NSFetchRequest(entityName: "FilmInfo")
request.predicate = NSPredicate(format:"id = %#", aFilmInfoID) // example
request.fetchLimit = 1
let results = context.executeFetchRequest(request, error:nil)! as [FilmInfo]
let object = results.first!

Answer 2

You need to execute your fetch request in your context.
var resultsArray = context.executeFetchRequest(request,nil)
if let arr = resultsArray {
//we have some results
var firstObject: FilmInfo = arr[0] as FilmInfo
var date = firstObject.date
}
If you are interested in only one object you can always set request.fetchLimit = 1
Getting more advanced you can also fetch only the date property:
fetch.propertiesToFetch = ["date"]
fetch.resultType = .DictionaryResultType
