I just tried it again, and now Xcode told me that: “ Action ‘boxClicked:' sent by 'Check Box' is connected to 'File's Owner,' an invalid target (Objects inside view based table views may only be

It does indeed. Thanks very much for telling me. Kind regards, Gerriet.

Though in concept, I love the idea of KV observers, in practice, I’ve found that they lead to too many crashes. I’ve switched over to sending notifications and it’s much less to worry about and

Gerriet, I am doing the same thing now on iOS. Here’s what I am doing and am open to better approaches. Being able to do this requires a special set up where the cell contents are retrieved from

So, doesn’t NSWorkspace’s activateFileViewerSelecting method do that?

I want to have a Finder window with “/a/hugeFolder/someThin"g selected. [ NSWorkspace.sharedWorkspace openFile: @“/a/hugeFolder/someThing” withApplication: @“Finder" ] results in an

It was the app delegate. I found another solution: The contentArray contains only a few dictionaries - less than a dozen. So I decided to observe all of them: for( NSDictionary *d in

This ought to work, so I think you should focus on finding out why it isn’t. What are you specifying for the target? It should be something that doesn't depend on the cell itself, like the view

macOS 12.6 I have an ArrayController which has ContentArray bound to AppDelegate.contentArray The contentArray contains MutableDictionaries with a key “Flag”, value: boxed BOOL. And a TableView

Just after posting, a web search turned up this, which is I think what I was looking

Hi all, Can anyone link any sort of documentation that explains what all the stuff NSView does for printing does? I’m sure there used to be documentation explaining this but I just can’t find it.

Did you try removing and re-adding the linked binary? It could be that the changes required for the newer versions to work would not function because of an API change if you wanted it to work on

Thanks, I have managed to get it working, but the reason is something of a mystery. Xcode 9 showed the same problem, so that wasn’t it. I created a new project and just added the CCToneGenerator

what I usually do to debug these things is pull the link line from the detailed build log, go to the same directory, run it by hand and ensure I see the same result. Then I

All looks OK. I’m going to try Xcode 9, just in case (grasping at straws perhaps). I did upgrade Xcode and the OS separately, but this particular project wasn’t recompiled until

It sounds like the one of a few things might help. Look in your "link to binaries” build section to see if any binaries are added twice, or are missing. Also, check to see in the build file phases

I’m using 8.3.3 ;) Yes, that was an update! Maybe I should try 9, but somehow an issue like this doesn’t quite seem like an Xcode problem. —Graham

Which version of Xcode? I haven’t had problems with Xcode 9.0, but 9.0.1 was released and some people are reporting various errors. Are you using 9.0 or 9.0.1?

Hi all, I’m suddenly running into some linker errors against AudioToolbox on a project after upgrading Xcode and installing High Sierra (not sure which of these did it). Undefined symbols for
