Hi all, I have some code which fetches an XML file from a URL and then parses it using NSXMLParser. Currently this code is contained within the viewController which calls it. I would like, for re-usability sake, to move the parsing code to an external class and call it from the viewController. I tried to achieve this as follows: Crea...
I have a NSTextField object in my window which has to be disabled when a check box is clicked. I have written a IBAction to receive the check box click and disabled/enabled the text filed based on the check box state. [mName setEnabled: [mNameCheck state]]; This work fine with the basic functionality, but I found some strange behavio...
How would I send a command to a Mac (which has network sharing turned on) over the Wi-Fi network that both it and the iphone is connected to? In my case I want it to open an application. ...
Hi All I am subclassing NSTextView and over-riding the drawRect method in order to draw an NSBezierPathWithRoundedRect around the textview, however - as it has rounded edges, they interfere with the text in the text view. Is there any way to apply some kind of margin or padding all around the text input area of the NSTextView so that i...
I have a NSArrayController bound to NSUserDefaultsController, and the array stores a custom class of mine, which conforms to NSCoding. It seems like I need NSArchiver, but I can't quite figure out how to glue it all together ...
I'm writing a Cocoa app. There is a socket in the application, and whenever the socket becomes readable I want to read data from the socket, process the data, and update the user interface accordingly. I want to integrate the read event check in the main loop, i.e. I want to attach the socket to the main loop and have the main loop call ...
Has anyone tried exporting data to Numbers in iWork? I want to generate a spreadsheet programmatically but I'm not having much success. I've tried unzipping a .numbers document and analysing the XML to see if I could interpret it but it's far too complicated. Also, I couldn't find the DTDs used by Apple. Judging by what's out there thi...
Hi, I'm creating an application, from which a part looks like this: I all dragged them to a window in IB, but the problem is that the NSImageView, Action Buttons (Suggest, Send, Poke etc...), Information NSBox, and Friends NSTabView can all vary in height. They should always be placed below each other, with a margin of 8px. Just like...
I'm going through a refactoring and reorganization of my application at the moment. I've realized that some of the separation between models and views, and their controllers has diminished and I wish to do some cleaning up. I have several key classes used in my app: NSPersistentDocument, NSWindowController, and a model class. The NSPer...
I'm trying to programmatically discover and then mount network volumes shared using OS X's file sharing from a Cocoa app. I'm using NSNetServiceBrowser to discover which servers are advertising file sharing - easy enough. My question is about the next step - how do you discover what shares are available for a given machine? ie. given th...

In a pure C++ world we can generate interfacing or glue code between different components or interfaces at compile time, using a combination of template-based compile-time and runtime-techniques (to e.g. mostly automatically marshall to/from calls using legacy types). When having to interface C++ applications with Objective-C/Cocoa fo...

Hi! I have a piece of network code that uses AsyncSocket but moves it to a separate runloop. I'm creating this runloop with the following piece of code: [NSThread detachNewThreadSelector:@selector(_workerLoop) toTarget:self withObject:nil]; and here's how my _workerLoop looks like (they're both in the same class): -(void)_workerLoop...

I know the UUID of a volume - as found in Disk Utility. How can I get additional information on the volume? Most importantly, I want to know its mount point. Looking at /etc/fstab doesn't do the trick. This does not list the root volume. I would at least need to figure out the UUID of the root volume to verify my known UUID against it...
