Sorry for the multitude of iPhone Programming newb questions but..
what is the reason for having an unsigned type for something such as
- (unsigned)count
for the NSArray class.
Why not just define it as
- (int)count
?
+8
A:
An array can't have a negative number of items, so an unsigned integer is a much better match for the kinds of values this method will actually return.
