All I want to do is find out the number of items in an NSArray and
store that as a variable, which I can then find the square root of.
The docs tell me that [NSArray count] returns an NSUInteger, but
exactly WHAT one of these is, or how I use it is baffling me.
An NSUInteger is just an integer that is 32-bits or 64-bits depending
on if your application is compiled for 32-bit or 64-bit.
a simple
int i = [myArray count];
crashes out, and I've tried various other types of variable to no
avail. Any thoughts? Am I missing something blindingly obvious here?
Are you getting an exception? perhaps myArray isn't really an NSArray
at the time that you are sending it the -count message?
