With CHTCollectionViewWaterfallFlowLayout implemented, my viewForSupplementaryElementOfKind and referenceSizeForFooterInSection are not called.
This only happens with collectionViews that use CHTCollectionViewWaterfallFlowLayout. The library readme states that it supports header and footer, but not seem to be the case? Or am I missing something here?

I've tried opening an issue but haven't seen anything.
Thanks!

I have been using Fancytree quite successfully for several years. Of late a new requirement has arisen. I would like to change the tooltip for a node that is currently visible. Is there a way to do this? How? Using an API? I have tried changing the tooltip property of an existing Fancytree node. Strangely, this did not work. What will work? Thank you.
Over on Github, this was resolved by Mr. Wendt. He suggested calling node.renderTitle() after modifying node.tooltip (which was correct) and he found a typo in my code. See Github issue #1093
I'm trying to add custom content type to existing page builder module in Magento 2 following https://devdocs.magento.com/page-builder/docs/create-custom-content-type/overview.html
Bit of a problem that docs is kind of outdated, but the biggest issue for me right now, is that for some reason, panel with settings of content type is not loading. Console doesn't throw any errors and I'm not even sure how to debug this.
Normal behavior: https://drive.google.com/open?id=1OClPda-WGuc7idNogUnTz0wi4ZSk_Qu_
Behavior of custom content type (settings are not loading at all): https://drive.google.com/open?id=1I-IeTImec-M8DuLfgjiA193mhm0Fwtd8
Maybe someone already stumbled upon issue like this and know possible ways to solve it?
Ok I've found out what problem was, so I'm answering this question in case someone will need this in future.
Check your ui_component xml structure, I was having an issue with naming there (namespace was not correct), and that's why it was not loading.
I already asked this in the Apple Dev Forum but received no replies, so I'll try here.
I'm unsure if this is a bug or whether I've missed something since I'm still very new to programming.
I have multiple view controllers and have made multiple classes. I have set the custom class "bit" of each view controller to the revelent class. When I ctrl-drag anything from the view to the relevent class header, I get the usual pop-up. I fill in the info, press connect, and BAM. It does the same kind of error whether I choose "Outlet" or "Action" It worked in the previous Xcode but I'm not sure if I've forgotten something.
The view controller and class that I added with Xcode 4 is still working beatifully.
I've tried adding the image manually but all that gave me was a SIGBART error just trying to get to the view. Again, I may have missed something, but I don't think there's much to miss is there?
Any help would be appreciated.
Just to eliminate a few things... I've deleted derived data, restarted Xcode and done a "clean". That's all I can remember that I've done.
Problem solved:
When selecting the implementation file. When I looked in the File Inspector, I found that under "Target Membership", the app name wasn't ticked. I ticked it and it now works well.
Since I didn't need to do that in Xcode 4, I suspect in Xcode 5, it doesn't do that automatically. Maybe that's a bug? I don't know if it was deliberate by Apple, but I think I'll file a bug report anyway since It's a bit of a nuisance.
I have a cocoa app that allows the user to enter a query. I'm using an NSWebView with a TextArea HTML object. The problem is, as soon as I type anything into the textarea, my document gets marked as updated. Does anyone know of a way to prevent this?
I've verified that using a NSTextField does not reproduce this behaviour, but I specifically want to go with the HTML/TextArea for styling.
So basically: Can I make it so an NSDocument does not get marked as edited unless I manually call:
[document updateChangeCount: NSChangeDone];
This post on the Apple mailing list seems to match your problem exactly.
The solution suggested is to set a custom undo manager to the webview (sounds like hard work), however a quick-and-dirty hack looks to me like subclassing updateChangeCount and perverting things to your way of thinking.
I am working on trying to make a splitview based application. I am trying to use Apple's MultipleDetailView example code
http://developer.apple.com/library/ios/#samplecode/MultipleDetailViews/Introduction/Intro.html
I have never really used example code like this (I usually just atart from scratch). All i did was copy the code into the correct classes of my app, but when I try to run it on the simulator the app doesn't open.
I feel like I am maybe forgetting something obvious, since I didn't code it myself.
Thanks!
The usual debugging technique applies. Put a breakpoint somewhere early in the program -- the first line of main() for instance, and debug from there. Do you hit the breakpoint? If yes, move forward through the code until you find the line that causes the problem. If no, try to back up even further if you can, and also look for any clues as to what's going wrong. If the app is running at all, there should be some sort of error message in the console output.
"...the app doesn't open" doesn't tell us nearly enough to help you. Something like "the app delegate is instantiated, but it's window and splitViewController properties are nil" goes much further toward getting to the root of the problem.
