However, if I make the window smaller than the image, the scrollbars appear as they should, but the BOTTOM of the image is locked to the bottom of the window, instead of the top of the image being locked to the top of the window. In other words, I w...

But I can't seem to find out how to do it in ObjC/Cocoa. I'm pretty sure it's quite easy but I fail to find any info about it. Thanks... ...
I'm writing some code that is wrapping up some CFNetwork stuff to do DNS resolution in Objective-C. Everything is fine and it's working, but I have a few questions: The callback function prototype for CFHost's asynchronous resolution is passing references to CFStreamError structures even though the documentation says CFStreamError is d...
I hope i did not skip this part in the ObjC manual but is it possible to refer to a class from within one of its class methods?

Hello. I know the iPod touch 1g does not have a speaker like the 2g, and the iPhone, but I do know that it has a small speaker, capable of making various beeps. Is there a way to make the iPod touch 1g beep, or does it only work on 2g and above? If so, what would the code be? Thanks, HiGuy ...
The @encode directive returns a const char * which is a coded type descriptor of the various elements of the datatype that was passed in. Example follows: struct test { int ti ; char tc ; } ; printf( "%s", @encode(struct test) ) ; // returns "{test=ic}" I could see using sizeof() to determine primitive types - and if it was a full ...

As someone that's new to Objective-C can someone give me an overview of the retain, assign, copy and any others I'm missing, that follow the @property directive? What are they doing and why would I want to use one over another? Thanks ...
When I try to crop an image using NSImage's imageFromRect, I get an EXEC_BAD_ACCESS crash about 50% of the time. This is something that runs on startup (triggered in an awakeFromNib), so the environment shouldn't be changing. I am not sure why it crashes one one launch and not another. When I have a breakpoint set before I crop the image...
