Hello,
I don’t understand this line
picker.delegate = self
what does it do?
Thanks!
What this piece of code does is simply inform the picker object that the current class will handle any delegate events. Your object creates the picker, then tells the picker that it will respond to any picker events. You could alternatively create an entirely different object to respond to picker events as well.
I hope that helps!
