I try, for simplicity's sake, to avoid intermingling C types and Cocoa
objects. I would probably rewrite your loop to use an NSMutableArray as
follows - *written in email, untested*:
NSMutableArray *allColumns = [[NSMutableArray alloc]
initWithCapacity:boardDimension];
for (NSUInteger i = 0; i < boardDimension; i++) {
// NSMutableArray retains objects added to it, so autorelease the
following unless you need it for something else
TileColumn *column = [[[TileColumn alloc] init] autorelease];
[allColumns addObject:column];
}
// Now you have an NSMutableArray containing all the columns, owned by you.
// If you really want an NSArray, perhaps for memory reasons, you can
follow up with:
NSArray *tableColumns = [NSArray arrayWithArray:allColumns];
[allColumns release];
// Now you have released allColumns and have an autoreleased
tableColumns - retain it if you need it to persist. You can of course
change the initializer calls to return either owned or autoreleased
objects depending on what suits you best - just follow the memory
management rules!
