Hi, Gabriel As far as I know, if it is not a standard application package, you cannot use the organizer to archive properly a package and then send it to the notarizing server. I struggled with it for a long time, more than a year, until Apple gave us the proper documentation in WWDC 2019 for u

Hi Sean Yes, I was bitten by that too, very, very recently, when I was translating a few files into Swift and I got warning when I didn’t use an optional for the object of the method. Actually, I suspect that’s a bug in the headers, or probably that’s a non-audited header for nullability. Alt

Re: Date Formatter relative date formatting

As a native Portuguese speaker, I can tell you that it is NOT normal to capitalize “Hoje” at the end or in the middle of a sentence. The same is true for “today" in English. Thus, I think these variations of capitalisation are bugs. A similar bug was true when the days of the week were not capit

NSScrollView and NSTrackingArea woes

Hi, I am implementing two custom classes, one of them is the document view inside an NSScrollView and the other is a subview of the document view. I need to create two NSTrackingArea’s to display the appropriate cursor when the mouse hovers over specific areas of the subviews. As instructed by

Re: Who is launching my helper?

I’m just guessing here but most probably your helper is being relaunched automatically by the OS itself by receiving a reopen command, because it was running before the user logged out. I think you need to either prevent that or handle that possibility in your code. I had a similar problem that

Re: 32bit vs 64bit and QuickTime/AVFoundation

I second what Mark said. I did exactly as he suggested. To move to 64-bit I isolated all QuickTime dependent code in a 32-bit only helper. The main app, the other helpers and a private framework are now fat binaries and I migrated all the media code to AVFoundation and related APIs. The 32-bit only

I would really appreciate if someone could help me with this mixed bag of problems I'm having while drawing a custom NSView: I have a textured window on which I display either an NSOutlineView or this custom view (both are subviews of the window's content view). This window has a toolbar with seve

No, isKindOfClass check for the superclass. It returns true if self class is myClass or a subclass of myClass. You should use isMemberOfClass: to got something equivalent. Yes, you are right. Thanks for pointing it out. because in the first example we are calling -class: in [self class

( [self class] == [aReceiver class] ) ? If it is, sorry for the noise, but I would find it weird that a pointer to a class instance also had the same end result as invoking the NSObject method 'class'. Is it? JV On 2009/01/25, at 14:07, Jean-Daniel Dupas wrote: Le 25 janv. 09
