I want my UIView subclass to position itself automatically when it is added to a parent container view.
Can I somehow detect when it is added and run my positioning code then or do I need to do something like?
[parentView addSubview:subView];
[setView calcPosition];
UIView provides the methods willMoveToSuperview:
and didMoveToSuperview
. Just override those to know when the view is added to another view (or later removed).
Write calcPosition
methord inside the subview and call it from the didMoveToSuperview
of subview
- (void)didMoveToSuperview
{
[super didMoveToSuperview];
[self calcPosition];
}
