I have asked this before but I think my question was not understood, so here goes again:
We do not handle memory anymore, since ARC does that. We cannot even invoke memory release commands etc.. So what CAN one do programmatically at RUN TIME to address a memory warning issue if the delegate receives the memory warning notification?
I do NOT want to know how to fix my code!!!
Code cannot fix itself at run time.
Assuming I have coded correctly, BUT still receive a memory warning, what can be done ..
ie Can you give an example of what to code into the
// Release any cached data, images, etc that aren't in use.
Of course you still have control over memory. You're just operating at a higher abstraction level with ARC.
You can use:
object = nil to clear a strong reference. When all strong references are cleared, the object is deallocated.
If you are familiar with manual reference counting:
object = nil; << ARC
is like this when doing your own reference counting:
[object release], object = nil;
