Here's what I want to do:
NSRange r = NSMakeRange(0,5);
id a = [NSMutableArray a];
[a addObject: r]; // but NSRange is not a NSObject *
With a boolean, I'd use code like this:
[a addObject: [NSNumber numberWithBool: YES]];
or with an integer:
[a addObject: [NSNumber numberWithInteger: 3]];
So what's the equivalent with a NSRange
? What I don't really want to do is create my own subclass of NSObject
to accomplish this. Surely there's a way with what Apple's already provided?
Use NSValue's +valueWithRange:
. To retrieve the range structure back, use the property rangeValue
.
[a addObject:[NSValue valueWithRange:r]];
...
NSRange r = a[4].rangeValue;
