I assume you mean needsDisplay. In my tableViewSelectionDidChange: delegate method, if instead of setting needsDisplay on the table, I say [self.table

Can you set the background to needsRefresh?

I have a view-based NSTableView in a scroll view. I want to customized the way that selection highlighting is drawn. So, I set up a controller as a delegate of the table, and in the delegate method

I've made some progress on mocking by defining a protocol containing the CKDatabase methods I call; an empty extension to mark CKDatabase as implementing that protocol; and a mock class that

when I was working on CloudKit I made a separate User account on my Mac with my developer Apple ID, iCloud enabled, then you can see and test the Cloud data using the browser interface. I found it

A specific test zone, perhaps when running in the test configuration? Do you have a helper that can detect the build configuration used to run your app? I posted some a while ago and can repost if

I've come up with a solution for this: I can't erase containers/databases, but I can erase a zone by sending a delete followed by a create. That's fine for my purposes because all my code so far

I seem to recall that Axel Kee on Twitter completed a project that might be related to this. He’s in Singapore and is at @soulchildpls on Twitter. But you know Apple. It would probably be best to

Hey, is anyone here using CloudKit? I'm getting started with it and have issues. There's some content on Apple's dev forums, but frankly even the new improved forums have awful UX (why couldn't they

Check Objective-C headers in teh foundation classes. In there, you can see how you can declare a function’s availability to certain OS versions. Once you see how Apple does it in Objective-C, you

Suppose I have a protocol that contains a method with a default implementation: public protocol A { func foo() } public extension A { func foo() {

I have what must be a common problem, and am looking for some architectural suggestions. Over the years, I've built custom objects (e.g., popup calendars, button menus, etc) which have now been

I’m wondering if anyone thinks it’s remotely possible to automatically connect an iOS device to a WiFi network with user permission. Sort of select a network, wait for a network access over

I have a storyboard-based app based on a split-view. I have edited the split view as shown in the attached screenshot. My goal is to have a single storyboard that will handle both iPhone and iPad

OK, I have this problem generally solved. There’s one more thing I’d like to ask though - when a tile draws to the screen, it is animated. In some cases that’s annoying, like when something

Thanks to everyone who chipped in so far — interesting ideas. The zOrder is in fact a float (CGFloat, so 64 bit), but as Jens points out, it can’t go on indefinitely. In experimenting with this,

Does anyone have sample code or just a few hints how to use CATiledLayer in a NSView on Mac? I’m reasonably au fait with using layers in a view in general, but this one is very minimally documented

I have been using the following code to determine if a system is set to 12hr or 24hr time for sometime… NSString *formatStringForHours = [NSDateFormatter dateFormatFromTemplate:@"j"

Sadly, this only postpones the problem — you run out of precision after a while. A 64-bit double only has about 52 bits of mantissa, meaning that some sequences of 52 reorders will cause a
