Just a quick update, as I've played with this some more: I have tried passing
in various ranges to -checkTextInRange:types:options:, thinking that maybe it
needed a typing range (of 1 in length), and trying to emulate the sorts of
ranges that get passed into the method by the text view (by overriding and
NSLogging to check the sort of ranges passed in); I've also tried specifying
the types (e.g. NSTextCheckingTypeReplacement and NSTextCheckingAllSystemTypes)
rather than relying on -enabledTextCheckingTypes and passing different things
into the options dictionary (which shouldn't be necessary), all to no avail.
For now kludging it with -checkTextInSelection: works, but I'd still love to
know how to use the -checkTextInRange:types:options: method if anyone has any
ideas...
Thanks and all the best,
Keith

Hello,
I am trying to force text checking in an NSTextView on Snow Leopard using the
new -checkTextInRange:types:options: method, but I can't seem to get this
method to work at all. I am aware that the documentation clearly states that
"this method *usually* would not be called directly" (although it does not say
"never" or "should not be") as NSTextView calls it from its various text
checking methods automatically, but my text view subclass adds other types of
substitutions which mean I need to force text checking on the built-in types
either before or after making my custom substitutions. (For instance, I have an
auto-capitalisation method that gets called in -textDidChange:. If
auto-capitalisation alters a word that is in the system "substitutions" list,
though, it prevents substitutions from happening, presumably because the
changed range gets affected before the substitutions code gets called.
Therefore in the situation where auto-caps is going to change
the text, I need to force text checking beforehand.)
The -checkTextInRange:types:options: method doesn't seem to work as expected,
though, presumably because the documentation is new and doesn't explain it
properly as yet. For instance, I would expect this:
// (Note that "self" here is an NSTextView subclass.)
[self checkTextInRange:NSMakeRange(0,[[self textStorage] length]) types:[self
enabledTextCheckingTypes] options:nil];
to have the same effect as this:
[self checkTextInDocument:nil];
or this:
[self setSelectedRange:NSMakeRange(0,[[self textStorage] length])];
[self checkTextInSelection:nil];
But it doesn't. Both of the latter methods - the action methods - work as
expected, checking and replacing the text where necessary - but the code using
-checkTextInRange:types:options: directly apparently does nothing at all - no
text gets replaced. (Even though the docs clearly describe the method thus:
"Check and replace the text in the range using the specified checking types and
options.")
(Note: [self enabledTextCheckingTypes] is not 0 - it includes quotes and text
replacement etc; hence the two action methods work. So I'm not doing anything
as silly as passing the method no checking types.)
I can get my auto-caps to work with the new substitution methods if I just use
-checkTextInSelection:, setting the selection before calling it and resetting
the selection immediately afterwards, but this is a bit of a kludge and I would
rather use the -checkTextInRange:... method directly if at all possible.
Has anybody tried this new method, encountered similar problems or found a
solution? Is there something I need to do in conjunction with this method to
get it working?
Many thanks in advance and all the best,
Keith
