Re: Avoiding leaks with "initWithCGImage"

ARC only affects Objective-C objects. It has no effect on CF objects like CGImageRefs, CFArrayRefs, CFDictionaryRefs etc. If you play with CF objects in an ARC app you still need to release them. You don’t need to release Obj-C objects and the compiler will warn you if you try to. —Rob > On

Re: Avoiding leaks with "initWithCGImage"

CGImageForProposedRect returns an autoreleased CGImageRef, so your CFRelease(imageRef) is an overrelease and likely the cause of your problem. The rest of the code looks fine, including the release of subImageRef (if it was uncommented). —Rob > On Aug 23, 2023, at 4:47 PM, JPH via Cocoa-dev

Re: iCloud does not appear on open, save or move to dialogs for Mac Document based app

Does it show up in the Finder’s Sidebar? Do you have the iCloud Drive checkbox checked in the Finder Preferences -> Sidebar section? If it is disabled there it won’t show up in the Finder or open/save dialogs. —Rob > On Nov 19, 2018, at 1:16 AM, Jim McGowan wrote: > > Hi, > > I posted thi

Re: Bothersome "NSView-Encapsulated-Layout-Height" constraint?

I was going to suggest the same thing. NSPopUpButton should do what you want. —Rob > On Jul 25, 2018, at 12:51 PM, Jens Alfke wrote: > > > >> On Jul 25, 2018, at 10:45 AM, Casey McDermott wrote: >> >> The goal is to auto-fill an account from what they type, and ignore typing >> if not a
