Very, very cool.  I'm new to the Mac platform but have developed with Borland C++ Builder and MS Visual Basic before, but Xcode and it's associated tools left me puzzled when I tried them.  This is just the sort of thing I need to get a good feel for how to get a working interface created .

hey

that looks like a good tutorial. I don't want to hijack this thread, only add more useful information.  i too have been learning cocoa recently. Here are a couple sites that I found useful:

a long series of articles, covering many important aspects of cocoa: http://www.macdevcenter.com/pub/ct/37 . the bottom ones are the oldest, and the most basic.

smaller site, also helpful: http://cocoadevcentral.com/

anyway, i hope these help others as much as they helped me.

btw, if i should post this in a separate thread, or forum, just tell me and i will (or mods can do it)

Would you mind taking a stab at updating this for xcode 3.0?

I'm fairly good with Cocoa, but I can't seem to get Interface Builder 3.0 to generate the source for my classes.  I assume it instantiates when you drag one from the library over to your app window, but the generating source code step, I'm just not finding it.

The docs seem to imply that it should do it automatically (that would be nice) but it's not on mine, 9a559.  Also, there is "Write Source Files..." but that makes files that are broken, and if you fix them, don't seem to operate.

I know it's some small simple thing I'm probably missing that Apple has made "easier."

Any ideas?

i have the same problem

You have to make the classes in Xcode, drag them into Interface Builder, then instantiate NSObject and set it's class to the header you just dragged in.

My first cocoa application
hehe, thanks a lot

Nice tutorial.

I'd suggest a step further down.
How can I make it, so when I leave the slider, the value also is printed in the console? (e.g. with printf?)


What I am trying to do is, how to connect "events" with real programming (and not only click & drag & drop)

I can't even seem to do the simpliest things.

I have 1 label that contains "1.23".
A 2nd label that has "4.56".
I want to add the values together... and display the total in a 3rd label.

> lblThree.text = (float)lblOne.text + (float)lblTwo.text;

I'm stumped.

Any help?

[lblThree setStringValue:[NSString stringWithFormat:@"%f", [lblOne floatValue] + [lblTwo floatValue], nil]];

Happy easter.
