Well assuming this so-called "UIButton" is a view class of your own
creation, why are you using NSArchiver but then NSKeyedUnarchiver
(keyed is recommended for all modern apps). The more common Cocoa
approach is not to "copy" the view, but instead have it in its own
dedicated nib where you can load a new copy as you need it.

If it were an NSView, archiving works for copying views, but maybe
UIButtons aren't archivable? (Guessing, obviously).
When you say it "breaks" what do you mean if you get no error
message?

I'm trying to add a copy of a view as a subview to the parent view.
This
is
what I tried:
UIButton* firstButton = [[UIButton alloc]
initWithFrame:CGRectMake(0,0,360,
360)];
NSData *btnData = [NSArchiver
archivedDataWithRootObject:firstButton]; //
Breaks Here
[parentView addSubview:firstButton];
UIButton *twin = [NSKeyedUnarchiver
unarchiveObjectWithData:btnData];
[parentView addSubview:twin];
It breaks when I try to archive the object, and I don't get any
error
message in the console. Maybe there's another error console (I'm
new to
Cocoa) that shows what's wrong.
Is there any way to copy or mirror a view?
Thanks,
Phil
