Alternatively you can use sortedArrayUsingFunction:context: without
risking the name space collisions that categories have at times.
And if you don't want to have to rewrite your category much, just
call the first parameter of your function self. Like:
NSComparisonResult LengthCompare(id self, id other, void* context)
{
return [[NSNumber numberWithInt:[other length]] compare:[NSNumber
numberWithInt:[self length]];
}
then you just call:
[array sortedArrayUsingFunction:LengthCompare context:NULL];

you'd need to write your own sort method to use with it, but it's pretty easy.
You'd add a category to the objects you want to sort.

Hi,
How would i go about sorting an array of strings in
ascending/descending order of string lengths. Is there an easy way
to do this, like using something like:
[array
sortedArrayUsingSelector:@selector(caseInsensitiveCompare:)], is
there a different selector i could put in there that would sort the
array by string length?
