I've started to read all available apple docs on this topic. A fast overview gave me a number of about 8.000 (eight thousand) DIN A4 PDF pages. About 10% of the content is almost equal for my feeling. After reading for 2 weeks now, I figured out that I would forget fast what I have been reading a week ago. Unless I start to do something ...

To phrase my question as simply as possible, is there a way to create a core animation sequence to repeat over and over until a stop? Specifically, I'm making a custom class that I want to have a -start and -stop method that will cause it to pulsate. Writing the animation code for the pulse is not the problem, rather, how to make it rep...

In my application I have some controls like NSButton and NSTextfield I want to turn invisible. I know I can do it n the Interface Builder but I need to do it in the code. I still haven't found the right message I need to send to the controls. ...
Back in the day of C/C++, the part of the language that really hung me up was pointers. I understand them now, of course. Now, Interface Builder Proxy Objects or more importantly, how to use Interface Builder and what to put in the .XIB window (window that contains the File's Owner, First Responder, etc...) for a given XIB. I've gone t...
I have created a simple NSWindow with an NSTextField and an NSButton in Interface Builder on Leopard. I set the window background color in my program. Everything looks fine when I run the program in Leopard. But when I run it in Tiger, the background color of the window is not set. It has a default Tiger look with horizontal stripes. ...
Hi! I'm developing a Cocoa (Touch) app and there's certain data (like own device information and a list of locations) that I have to persist between different views and controllers. I thought of storing it as instance variables in my App Delegate, but addressing the delegate is quite cumbersome (no joy typing [[[UIApplication sharedAp...
In the wikipedia article on Cocoa it says: There are also open source implementations of major parts of the Cocoa framework that allows cross-platform (including Microsoft Windows) Cocoa application development, such as GNUstep, Cappuccino, and Cocotron. Yet when I looked into whether Mac application Tweetie was available for windo...

What I really like in C# are generic lists. A list that can contain only one type of objects. Is there something like a generic list in Cocoa/Objective-C? As far I only know NSArray who will take a pointer to any object. ...
In a project that I am currently working on I have an transparent NSWindow overlayed on a QTMovieView. At certain points I slide a custom view into this child window with animation so that it is displayed over the movie for a short period of time. The only odd behavior is that the animation is smooth on a Mac Book Pro but on a Mac Book(S...
I'm recording from a webcam. The camera looks great in PhotoBooth. However, when I preview it in my program with a QTCaptureView, or record it to a file, it is very, very slow. The reason is that QuickTime is giving me the maximum possible resolution of 1600x1200. How can I force a more reasonable size for both my QTCaptureView and my re...
In many Books and on many Sites I see -drain. Well, for an Autorelease Pool that sounds cool. But does it do anything other than an release? I would guess -drain just makes the Pool to -release all it's objects, without releasing the Pool itself. Just a guess. ...
I need to write a simple ping method in Cocoa/Objective-C. It also needs to work on the iPhone. I found an example that uses icmp, will this work on the iPhone? I'm leaning towards a solution using NSNetServices, is this a good idea? The method only needs to ping a few times and return the average and -1 if the host is down or unreach...
