Hi. I'm slowly coming up to speed with the slightly twisty relationship
between Cocoa and C (at least from a perspective of one who doesn't
know C very well yet.) My current problem:
NSRange myRange;
NSMutableArray *myArray;
myRange = NSMakeRange(0,119);
myArray = [[NSMutableArray alloc] init];
[myArray addObject: myRange];
This doesn't work, because of "incompatible type for argument 1" on
that last line. It looks to me like I can only put Objective-C objects
in NS(Mutable)Arrays; I get similar warnings, though not errors, when I
try to put an int in one.
With ints I can wrap them in an NSNumber at some unknown cost in
performance, but with NSRanges I'm sort of stuck. I hope to heck I
don't have to resort to stashing pairs of NSNumbers instead of
storing nice clean NSRanges. I don't even know how I'd do that
cleanly. Arrays of 2-item arrays?
[NSValue valueWithRange:myRange];
