It makes the code copy/paste-able. No dependency on the name of class you are adding it to.

Why is this necessary? Apologies if I'm missing something obvious, but what's wrong with literally using DataSingleton (in your example)? Even if the method is called on a subclass it should still

Awesome. TY. +1

No no - not: static id *instance; but static id instance; The id type is itself a pointer to an object. - Jon

I wish. Pointer to non-const type ‘id’ with no explicit ownership.

Couldn't you just make it: static id instance; instead? - Jon

I did this a few years ago but can’t find my sample and figured I’d ask the brain trust here. In iOS, when I’m making an Objective-C singleton, in the public method that returns the

Or have your subclass implement -isFlipped to return YES. Keary Suska Esoteritech, Inc. "Demystifying technology for your home or business"

What you need is #if MAC_OS_X_VERSION_MIN_REQUIRED < MAC_OS_X_VERSION_10_11 MAC_OS_X_VERSION_MIN_REQUIRED is the deployment version, and MAC_OS_X_VERSION_MAX_ALLOWED is the SDK

Hi, This seems to do the trick: -(LTWNativeRectType) adjustRectForPlatform:(LTWNativeRectType) theRect { LTWNativeRectType myRect; myRect = theRect; myRect.origin.y = self.frame.size.height -

Mac uses bottom-left for the origin, which is why everything is "flipped in the Y direction". You *can* do the calculation to move the origin to top-left and scale the transform in the opposite Y

tell application “MyApp" open alias "Macintosh HD:path:to:file" -- HFS path end tell or if you don't want to use an HFS path directly: set theFile to POSIX file "/tmp/abc" as alias tell

Hi, I’m converting some Manual Layout code from iOS to Mac. I’m overriding “layout” in my class, it calculates and sets the Frame Rect for all its subviews. This works ok on Mac, except, as

Hi, Yeah, realised that afterwards, I made it a property for now, it will be retained by the App Manager once I add it, Cheers Dave

Sorry, if my explanation was not too clear. This is the code: - (void)applicationWillFinishLaunching:(NSNotification *)aNotification { NSAppleEventManager *sharedAppleEventManager = [

Your code answers that question. What you don't explain is what you want to do, presumably with the descriptor, when you get there. You ask about creating a typeAlias eventDescriptor, but your code

I have some (old) code like: NSAppleEventDescriptor *eventDecriptor = …. DescType descriptorType = eventDecriptor.descriptorType; if ( descriptorType == typeAlias ) // ‘alis’ { … How to

I need something like: #if MACOSX_DEPLOYMENT_TARGET < 10.11 ← this of course does not work … some code, which is only needed in this case … #endif Is this possible? Gerriet.

No, I'm not talking about subclassing NSView. I'm talking about writing two category methods in Objective-C, setBackgroundColor: and backgroundColor. In Swift, you'd call a category an extension. With

(code edited to get rid of the noise) That’s what you’re doing, really? The window controller you create here has no owning references outside this method’s local variable, so it’s going to
