I know this is a subject that comes along on a regular
base :) But in all pages I found I cannot say that I
understand it completely. I want to know what is this
call exactly for.
If I have a component which consists of sub-components
I have to take care what is returned by the children
call. I know it works without but it causes problems.
I don't know exactly when the problem arises.
Same is with sub-components which are stored in an
ivar and which get exchanged according to the state
of the component.
So when do I have to use registerObjectForBacktracking?
- If I use sub-components in an ivar and want to be sure
the back button is working properly?
- Any other cases?
- Are the children call and the registerObjectForBacktracking
thanks in advance,
