Let's say that I'm receiving data from the network and need to store it in

Hello,
If you are still learning I would recommend NSImage, it's the easiest to use.
If you need many images and high framerates I would recommend to use OpenGL.
CGImage, CIImage are rarely used for special purposes.. I wouldn't bother with
them at the beginning.

I have an NSImage. I want to save it with a CGImageDestination. the
CGImageDestination wants a resolution.
I know that the NSImage is resolution independent, but I happen to know that
this image has only one NSImageRep. I also know that the image is bitmapdata.

Your formula is inverted, and you should multiply before dividing to get best

I'm trying to take an attributed string from a PDF document and reproduce it on

basically, i write to the database using

Ok, so a little research reveals that the problem is much earlier than I
thought: the images I'm creating have no resolution data.
So, the next question is: Given a bunch of bitmap data, and a resolution, how
do I create an NSImage (or CGImage or CGImageSource) with the correct
resolution?

I'm not sure why you feel it necessary to drop your selector view directly into
the map view? My experience
I’ve got a place in my code where I need to block waiting for an
otherwise-asynchronous action to complete, so I use a fairly standard technique
of running a nested runloop. But sometimes the runloop just keeps waiting
forever even after the action’s completed, so my app locks up.

Thank you david,
I think i'll try serializing it and de-serializing it

This is a noob question, and as I pour through the docs, I thought I would
ask here too.
I have buttons that have different text colors. All I would like to do is to
check the color after it's been clicked.
-(void) aButtonWasClicked:(id)sender
{
UIButton* resultButton = (UIButton*)sender;
UICol
You shouldn't be relying on the color of a button to determine what to do next.
The color of the button should reflect some state that's maintained internally
by the controller, and you should rely on that state to determine what to do
next.

Well, to clarify, do you really mean "size"? I would assume that
imageRep.size.width == image.size.width (both are in points), but
imageRep.pixelsWide would be different, if the resolution is not 72 dpi.
