I can’t remember where I mentioned those two things, but they should mean the same thing.

It's a 49" widescreen. :-)

Unfortunately, my friend, not. I am working through an M.S. in Data Science and have been pretty busy as of late. That said, I'm considering jumping back into contributing to local meet ups. I'll post here if I get around to the second part. I hope you at least enjoyed part one. :-)

Christian Di Lorenzo Thanks Christian! Really enjoyed part 1. Good luck on your M.S. degree!

I haven't done much unfortunately (in the way of talks since this one). I'm working on an M.S. in Data Science while working on both iOS & web projects. I do hope to get back into the swing once I finish or during a break. Thanks for asking and sorry I can't promise more. :-( Do let me know though if you are interested in a particular elixir talk. You might give me some motivation. :-)

Your question is not really related to this tutorial. I'd recommend getting assistance from great sites such as hackhands.com or codementor.io.

You'll need to create a delegate from the cell back to the table view controller after the date has been picked so even if the cell is the reloaded the data will be propagated properly. In other words, the date will not stick around unless it has been set in the underlying data source.

You'd likely have to create a new cell subclass (with it being properly registered with a cell reuse identifier) and then insert new content when expanded. Hope this helps!

Thank you

You'll need to be more specific for me to be able to be of any assistance.

Like, in the video you have two cells...the first cell expands with a slide animation and the second cell with a fade effect, how do I make both the cells with same expand animation.

you get the slide animation whenever there is another cell under the expanding cell. If not you get the fade

You need to have a conditional check in the heightForRowAtIndexPath delegate callback to always return the expanded size if the indexPath is referring to the first row. Hopefully, that makes sense. If not, please let me know.

The reason for KVO is that cells can be changed by the table view or other calls could be made to change its height without specifically telling the cell to update is contents. Does that make any sense? Please let me know if you have any additional questions.

Christian Di Lorenzo Thanks Christian!

Somehow disabling animation in the reloadRows section fixed it. I still have the animation of the cell expanding, but now there is no more flicker on the cell. What the...? But it works!

Doing that had an unintended consequence of the item being hidden not being hidden until a split second after the cell has collapsed. So that's not ideal. Back to flicker land...

Fixed! Replacing the reloadRows line with tableView.beginUpdates() tableView.endUpdates() solved the flickering problem and works fantastically.

Well... sort of. This has the unintended consequence of the hidden area being hidden instantaneously when unselected with no animation. But the initial tap animates.

I'm glad you got it all figured out. Let me know if I can be of further assistance.

I'm sorry I missed your comment in my notifications! :-o The reason for this behavior is likely that it still has not recognized the class of the cell. One alternate approach if you cannot get that to work is to create a custom nib for the cell. That way, you can reuse it in other storyboard controllers without the need for duplicating the XML :-). Let me know if this helps or if you have additional questions.

Yes. You can check it out at github.com/rcdilorenzo/vimfiles. Feel free to star the repo if you like it :-). It's changed a little bit but I would say for the better.

Unfortunately, I haven't done it yet. It's a monthly meet up group and I've been pretty busy between my undergraduate and work. I'm hoping to do the part two early next year. Really sorry for the wait.

thank you Christian, good luck

+Brandon McKay Crooks Thanks!

I'm using MacVim and using a remap in normal mode "<leader>t" to run the tests in the example. Is there something else you were trying to find out about the setup?

I was just interested how you'd go from/to command line while in editor mode. I'm not very familiar with vim so I might check it out. Have a nice day

Using ":!" you run shell commands. Like :!ls

Hmm... It sounds like a pretty specific problem. I'd be happy to help if you have it publicly available on GitHub or one-on-one at www.codementor.io/rcdilorenzo

Christian, I was able to figure out my problem. I had to adjust a couple of priorities with the constraints and found that programmatically bringing the expandedView to the front of the UIImage helped. Thank you again for your help and your amazing tutorials! I look forward to seeing future ones! :)

+Bob Bob Excellent. Glad you got it figured out.

I will... as soon as I do them. :-)

I realize it is kind of off topic but do anybody know a good website to stream newly released movies online?

@Davion Dean try FlixZone. You can find it on google :)

@Kylen Leonidas yea, I've been using Flixzone for months myself :D

@Kylen Leonidas Thanks, signed up and it seems like they got a lot of movies there =) I really appreciate it!!

+Jasdeep Narang Thanks so much!

hi Lorenzo, very nice intro, why dont you start a elixir tutorial series? it will be a hit here on youtube.. because couldn't find any good stuff about elixir here on youtube... BTW thanks for this video ...

Ah, if time were only on my side! Do you have any particular topics in elixir that you would be interested in hearing about?

I'd love to see more in depth coverage of supervisors and starting process dynamically.

Nathan Leniz I'm hoping to do part 2 at the same monthly elixir meetup group sometime this year. I'll definitely be covering supervisors and dynamic starts of processes in that talk.

+David West I've definitely thought about more content but am not sure what people would be interested in learning about. Any ideas? As far as multiple levels of nesting, I would probably reconsider the UI to perhaps use a long-press on a cell to bring up a menu. I know that the app "2Do" does this quite efficiently to expose some more options (as seen in this screenshot: pasteboard.co/2Bwrv0iZ.jpg).

Christian, I am personally using Firebase for my new app and I see a lot of movement here with Parse disappearing. However there is a distinct lack of video content around this, so knowing how to integrate Facebook and social platforms & how to extract information from those platforms (profile pic, location etc) in order to dump that data into Firebase....this would be really useful stuff. Some of the more complex but useful stuff for iOS apps, which goes far beyond just simple "Facebook login". I have loads of ideas about content though so best to keep my mouth zipped ;)

Christian Di Lorenzo As for the long-press, it's not a bad idea but I guess just with a simple tap on the second level item, it could load a custom modal with the content I need. I have used long-press and force touch within my app, but a lot of users just forget to use it. I was just hoping that I could have for example 3 sections within my settings tableview ("About Me", "Social", "Preferences") & each has about 5+ items that will need editing, so having an example of drilling down one cell further, would be really useful without displaying every single field and its option when you first click on the section.

+David West Unfortunately, I'm not a Facebook user and am not ready to jump on it. Any other ideas? :-)

Twitter? :p Another huge task I have at hand is finding out how to integrate contacts data into an app and integrate that with either Firebase, CoreData or any back end. Knowing how then to check which of those contacts have downloaded the app (and being able to contact and interact via messaging/requests) and inviting those users that haven't, would be super useful. Haven't found anything on this AT ALL, but it's one of the most valuable features for an app creator in my opinion.

+Keshav Aggarwal I'll need to know in more detail what the actual error is that you are seeing in order to assist.

+Christian Di Lorenzo Everythings works fine, but when I try to click the cells to expand them it expands the cell but then XCode takes me back to the project, saying "terminating with uncaught exception of type NSException" Cell Expander[14445:1896395] *** Terminating app due to uncaught exception 'NSRangeException', reason: 'Cannot remove an observer <Cell_Expander.PickerTableViewCell 0x7faa49cf2d60> for the key path "frame" from <Cell_Expander.PickerTableViewCell 0x7faa49cf2d60> because it is not registered as an observer.'

+Christian Di Lorenzo I used your code from github and it worked

+Keshav Aggarwal Excellent. If the code on GitHub was helpful, feel free to give me a little encouragement by starring the repository. Glad you got it all worked out.
