Ah yes, external symbols in a dynamic library--you do have some chance of
looking them up at run time ;-)

Cool, I didn't know that CFBundle exposed

You should be able to look up extern variables manually, and you can use

Functions are not the same, because a function's name is a necessary part of
the runtime. A co
I can open a library and lookup a function by name using dlsym. These
constants are EXTERN. It seams there should be away to look these up as
well.

This is C, and just as with variables, the names are not there at runtime.
If you really need to do this, you'll have to build your own lookup tab
The constant *is* an NSString; essentially you could do:
NSString *constValue = NSDeviceResolution;
Though, that may be a little redundant.

This would work for finding out what the name is as well as logging it.
What if I'm getting a string passed in that is the name of the constant and
I want to return the constants string value. Is there a way to do that?
something like...
NSString * constValue = [SomeToolToLookupConstants constant
I think you're confused: the constant *is* the string; there is no lookup to
perform. You can do anything with it that you would do with any other
non-mutable string: log it, setStringValue on a text field in the user
interface, setMessageText in an alert, and so on.

Have you tried
[NSDeviceResolution description]
or
[NSString stringWithString:NSDeviceResolution]
?

Just log it, same as any other string:
NSLog(@"%@", NSDeviceResolution);

Is there a way to lookup what and NString constant is at runtime? I want to
know what the string is for a given constant. For example I would like to
pass in the constant name ( i.e. NSDeviceResolution) and get back
the NSString that constant represents. I know in this case that the Constant
name a
13 matches
