Entered the parameter in front of the class:

let defaults = NSUserDefaults.standardUserDefaults() , after it there is a button that makes a comparison, and in it there is a picture + animation and text input:

 if TextField1.text == navigationItem.title { self.StarTextField.hidden = false UIView.animateWithDuration(4.0, animations: { self.StarTextField.frame = CGRect(x: 142, y: -800, width: 316, height: 158)} defaults.setObject(StarTextField, forKey: "StarTextFieldData") return stopFlashingbutton(stopListening()) } else { print("inCorrect TextField") }

sort of like should save the picture in memory. Further ViewDidLoad () I write:

 defaults.objectForKey("StarTextFieldData")

Run, crash ... what to do?)

Ps is the Spark CollectionViewController along with the ViewController (the button is in the VC).

    NSUserDefaults cannot by default store pictures. Only such types are supported: float, double, int, Boolean, NSURL, NSData, NSString, NSNumber, NSDate, NSArray, NSDictionary. I would save the image to a file, but you can also transfer it to NSData and then save it in the user settings.

    • Thanks, I will transfer it to NSData. And what does it mean (I would save the image to a file) through a binary view? - Alex Gr
    • Yes, in the file. If the picture is one, you can always store it with the same name. If you have a bunch of similar ones, then you can store a dictionary with file names in defaults, or even have a folder with all the program files - make a choice based on the features and growth prospects of your program. - AivanF.
