Question

How can you clear the contents of an array and a UIImageView? So that the array and the UIImageView aren’t deleted, but instead “cleared” of what was stored in them?

Answer 1

You need the mutable array for ‘clearing’, call removeAllObjects method:

[array removeAllObjects]; 

Set image property for UIImageView to nil in order to ‘clear’ it:

imageView.image = nil;
