Swifty question, macOS: As part of its functionality, my sandboxed app allows users to search for files across the entire filesystem. In the results of the search (displayed in an NSTableview), I

I'm doing the development of a small app on 10.10, so all the 10.11 additions to NSCollectionView aren't available. I have a window filled with an NSCollectionView in a scrollview, which contains 1

Did you call -reloadData after resizing the itemPrototype? You have to get the collection view to regenerate all the views with the newly resized prototype. - Jon

Annoyingly, reloadData wasn't introduced until 10.11, so that's not going to work. Sent from iCloud's ridiculous UI, so, sorry about the formatting

Oh right - well, there's the manual 'reloadData' method - set content to an empty array, then back to your content array :-/ - Jon

Got it working simply by changing the collectionView.maxItemSize to the size I want in the NSViewFrameDidChangeNotification callback. Whodathunk. Sent from iCloud's ridiculous UI, so, sorry about

iOS - Landscape Only. Hi, I have a View Controller in a Storyboard that contains a hierarchy of Stack Views, the leafs are a Custom Class that inherits from UIView. The Custom Class LTWGameCellView :

Mike Ash has been offline for a while, but his Friday Q&A is back with a detailed line-by-line analysis of the objc_msgsend function on ARM64. This is the core Objective-C runtime function that sends

Hi All, Does anyone know of an alternative for Auto Layout. I find myself wasting so much time with it as to be ridiculous, so I’d like to get away from it if possible. I’m writing a Game for

No. Find a good guide that will really teach you how to use it correctly and you'll thank yourself for taking the small amount of time it takes. What's AU? Audio Units? Steve via iPad

It sounds like a really easy task. Unless there is something else you haven't mentioned the basic idea is to have two views that sit side-by-side, where the ratio of widths is 1:2. If so then you end

There isn’t one that I can find and there’s no help available just people telling me to find a good guide! If there was a good guide I’d use it - there isn’t one! So the best thing to do is no

Hi, As I said, the board view is working ok with Auto Layout and also the Frame of the Player View is also working, but that’s the easy bit! I want to display the following information: Game: 999

That’s been my opinion of auto-layout too … in theory it should be awesome, but configuring it is ridiculously complex. Every iteration of IB seems to make some of the process easier, but adds

Great. Where’s that good guide? Xcode’s own documentation is so sparse as to be useless. The 3rd party books I’ve seen are massive doorstops aimed at newbies that spend 990 pages on the basics

Jens, Dave, I agree that auto-layout is a bit touchy. If it's any help, I think that under the hood it is solving a problem in "linear programming," https://en.wikipedia.org/wiki/Linear_programming

BTW, frequently I wish for the boxes & glue (& penalties) layout model that Plass & Knuth famously used for typesetting (TeX and all that). I believe the default layout manager for NSTextView uses

Hi All, Do I *need* to add constraints to a Scroll View or the Views inside a Scroll View? I’m trying to avoid applying any constraints in a View, I’ve started again using the old fashioned way

Sorry should have said, XCode 8.3.3. and iOS.
