Answer 1

Use -

NSData *tempArchiveView = [NSKeyedArchiver archivedDataWithRootObject:self.view];
UIView *viewOfSelf = [NSKeyedUnarchiver unarchiveObjectWithData:tempArchiveView];

Similarly -

NSData *tempArchiveViewController = [NSKeyedArchiver archivedDataWithRootObject:self];
UIViewController *controller = [NSKeyedUnarchiver unarchiveObjectWithData:tempArchiveViewController];
