In IB one can instantiate controllers, build up references to UI elements, and define action targets. It is also possible to do that programmatically. I wonder what (most) seasoned Cocoa developers prefer? In many other environments, I would not bother too long with interface builders (lower case), but the Apple tools are clearly a clas...
Can anyone point me to a really simple hello world type of application that introduces ScriptingBridge? Something that takes you step by step to creating a 1 class - 1 method project that can be instantiated from ruby/python/applescript, etc. I'm having a hard time wrapping my head around what is actually required to create a scriptable...

In the Core Data Programming Guide under "Transformable Attributes" here: http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/CoreData/Articles/cdNSAttributes.html It is stated "You can now use the attribute as you would any other standard attribute, as illustrated in the following code fragment:" The follow line of ...
I am trying to subclass NSSlider to create a control called a jog dial. Basically what I need is a slider which always starts at the middle and when it is moved to the left or right it will send notifications every so often (determined by an attribute one can set) informing its container of its current value, then when you let you go of...

Since the last question similar to this one is from 2008, I thought I'd ask it anyway to see what's new since then. I'm looking for books or other resources (though I prefer epubs for reading them on the go) for learning how to use DTrace, preferably but not necessarily for Cocoa, ruby or node.js development. ...
I'm trying to get the integer value of an NSNumber initialized with a float and I was expecting that intValue handle the conversion (as the docs say). #import <Foundation/Foundation.h> #import "Fraction.h" #import "Complex.h" #import "ComplexMathOps.h" int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutore...

My app uses Core Data with a simple model with two entities, 'Category' and 'Item', both with a 'name' attribute and a relationship one-to many (a category has many items). In IB I have a tableview and a Array Controller for the items. Also a textfield and a comboBox (for user type items name and select a category) and "add" button. Wh...
I have implemented thread-targeted notifications as per the Apple document "Delivering Notifications To Particular Threads" (http://developer.apple.com/library/ios/#documentation/Cocoa/Conceptual/Notifications/Articles/Threading.html#//apple_ref/doc/uid/20001289-CEGJFDFG) in my app, and it works great when run in the Simulator (iPhone 4 ...
Hi! In my small Core Data application I have some NSTableView views binded with NSArrayController controllers in Entity mode. When I try to import some big amount of data to my table in background thread, after some successfully added imports (from dozens to hundreds items) I get crash with log: Serious application error. Exception w...

In interface builder, I have an NSWindow with an NSView subview, and a custom NSOpenGLView as a subview of the NSView. I have my depth buffer set as 24 bit and a double buffer enabled. Everything else is set to the default value. I've used my NSOpenGLView elsewhere so I know the OpenGL parts work correctly. If I put an NSLog call in ...
Hi, I've got a custom image browser view with IKImageBrowserCell subclass where I've added a little sign graphic that I would like to animate on some occasions. It's kind of like the "i" sign on Panic's Coda Sites view (which I'm guessing is an ImageBrowserView customized.. right?). On Coda's sites view, if you hover on a project the l...
