According to Apple's documentation (Programming Topics: Strings),
NSScanners are deprecated. They suggest using NSFormatters instead. Is
it really so? I think NSScanners and NSFormatters serve two different
purposes. E.g., how can I use an NSFormatter to parse a
string, say, to
discard spaces and newlines (or whatever parsing process you like)?
Apple engineering managers have said here more than once that
scanners are
NOT deprecated. I don't know why that line still appears in the
documentation. I think the current intent is that scanners are
particularly
useful for writing formatters, and that otherwise formatters
are probably
more useful than scanners for many applications.
There also seems to be a mention of Java there in the docs.
NSScanner's API wouldn't translate very well into Java, plus
Java has its own StringTokenizer class that people can use, so
I'm guessing that was the original intent of the statement. I
can't say that NSScanner is a particularly fun class to work
with, either...
