I had a similar problem with Mac apps until a few months ago. Sometimes gdb would symbolicate, sometimes not. The problem was that, by default, gdb uses, er, Spotlight to locate dSYM files. The fact that I always put them in the same directory as the target app didn't seem to help. Surprise

I have two monitors connected. When I call NSreadPixel with a point that is on the main screen, origin 0,0 it returns the appropriate NSColor; When I call NSreadPixel with a point that is on the 2nd screen, origin -1280,0 it returns nil as the NSColor; So, how do I get the NSColor for a pixel

What I'm working with is a library that makes a QR code. It was built for iOS but I need desktop OSX (which, on a side note, seems silly because when you MAKE a qr code,  you'd usually want to print it right? Otherwise phones would just read them. Anyways...). It was easy enough to adjust the li

Hi Luc, how are you? When the user drags the divider and collapses it, the split view retains the view's frames before the collapse and that's probably something that is giving you some problems. In this sense, there are two different behaviors going on when a collapse happen: 1) If the user d

Hi, I'm really very close to having a working NSSplitView with animated "collapse" & "uncollapse" of the subviews, but there still is a problem when one of the subviews is first collapsed by dragging the divider over the subview's minimal size as controlled by the delegate. When I expand such

Hi all. I'm looking for leaks in my iPhone app and apparently finding some. Unfortunately, Instruments will not show my app's symbols, making it pretty worthless. I've tried "Re-Symbolicate Document", but this does nothing. When I navigate to the location of the app and dSYM files (which do exi
