The goal of this week was to implement custom navigation beyond the standard tab and navigation controllers.

Nice job on completed the required's and getting an optional in too, it's great to see that you're having a much easier time of it!

A few notes on the code:

• be very careful in your viewWillAppear func to use the pairing super.viewWillAppear call. In your code you paired it with a super.viewDidAppear and this could have unwanted side effects. Same for your viewDidDisappear you called super.viewDidAppear...
• in your viewDidDisappear you run an animation: it will never be seen since the view has fully disappeared. When your compose view does actually disappear, it will be removed and destroy itself, and the next time you open the compose view it will create a new one with viewDidLoad, so there is no need to reset to starting positions there.

Typos! Sorry about that. Thank you for pointing that out (and for the viewDidDisappear tip.) I fixed these and committed the changes. (Although now I have a strange behavior with one of my images - it drops back into the view on viewDidDisappear - maybe we can look later.) //cc @drnick23
