It says that the name should be in a set of predicates, which are boolean.
That doesn't make sens
Maybe another clue, if I NSLog the predicate, I get this:
name IN {{"name" = "Jones A."}, {"name" = "Williams S."}, {"name" =
"Brown M."}, {"name" = "Tobias S."}}
That seems as expected to me.

It looks to me like what you're doing should work as you expect. I don't think

Hi,
I have a plist with an array of dictionaries.
Now every of these dictionaries has a key 'ID' with an integer.
Now how I can get only one dictionary element out of this array where key is

Thanks for the reply, I'm a newbie and I'm still trying to figure out how are
things done in Cocoa.
I have another related question I'd like to ask you guys, cause I've searched
through documentation and tutorials but I cannot find the exact answer.
I'm trying to implement Model-Controller-Vie
A couple more things I've thought of:
- There is such a thing as a grayscale image that uses floats instead of
bytes for values. You may not even need to do a conversion.
- You may even be able to wrap your buffer up in an image rep without
copying it.
I don't use NSImage; my custom image views
Martin,
Have you looked at the API for CGImage? If not, this may be helpful as well.

You would use the methods of NSBitmapImageRep that allow you to get/set the
entire image buffer at once.

Hello,
I'm new in cocoa, and I want to accomplish something in a program i'm
developing.
I have an array of floats, that is basically a matrix, and I want to display it
on a view as a 2D grayscale image, with each pixel in a gray tone proportional
the value of that float.

Works fine.
"theArrayOfDictionaries" contains NSMutableDictionaries.
