CKComponentController::componentTreeWillAppear not called

[myeyesareblind]

Those methods are not called on CKComponentSubclass:

• (void)componentDidAcquireView
• (void)componentWillRelinquishView
• (void)componentTreeWillAppear
• (void)componentTreeDidDisappear
  Not sure if I am missing something

[adamjernst]

They're called on CKComponentController, not CKComponent instances.

[myeyesareblind]

Yeah, that is what I actually meant, see title. They are not called on ComponentController.

[adamjernst]

Ah I see. Can you submit an example project?

[myeyesareblind]

This does happen in Example project, simply add InteractiveQuoteComponentController with those methods.
-(void).*mount methods are properly called, those 4 - not.

[adamjernst]

componentDidAcquireView and componentWillRelinquishView will not be called because InteractiveQuoteComponent itself does not have a view. (Only its sub-component CKStackLayoutComponent does.)

However componentTreeWillAppear and componentTreeDidDisappear should be called. That warrants further investigate.

[adamjernst]

Verified this is a bug. Assigning @benlodotcom to fix.

[adamjernst]

Actually I'll take it

[myeyesareblind]

It works, thank you.
There is another thing now.
Currently, if you ask dataSource for not existing indexPath, it will crash since there is direct access to NSArray[index].
What happens for me is that I delete a cell and receive didEndDisplayingCell, the app crashes on announceDidDisappearForItemAtIndexPath because the model was deleted.
It might be better to simply return nil I guess.
Minor thing since I can actually check in my model, but still...

[adamjernst]

That's bad — opened #129 to track.

@myeyesareblind Hi guy! Can you help me to submit your example project to me? Thank you very much!

[myeyesareblind]

@thanhturin what exact issue are you working on? componentTreeWillAppear is fixed now

[thanhturin]

@myeyesareblind : I'm sorry about my late reply! I had the same problem 3 days ago. But i already fixed it. Thank you for your listening :)
