Hi All,
I've run into a situation where it would be great to have a
multidimensional NSArray or NSMutableArray. Is there such a class?
If not, any suggestions on the most elegant solution?
Thanks,
Daniel
It's actually one of the major annoyances (to me anyway) of working
in pure Obj-C code on this project: there is no direct support for
multi-dimensional arrays, or even static arrays of PODs. Implementing
an NSArray of NSArrays just feels ugly, and the syntax to access
items is awful. And having to revert to good old-fashioned C-style
indexing (e.g. myArray[y * rowLength + x]) is annoying. Since my
arrays are part of larger objects, I end up writing an accessor that
looks like [self itemAt:x:y]. I miss the simpler myArray[x][y] syntax
of C++, and the STL containers, and the temptation is always there to
start mixing the two languages; but I swore to myself I'd write this
app in pure Obj-C so I could honestly know what it's like.
All I can say is:
#define x<y> [x objectAtIndex:y]
