It would be nice if NSSpellChecker offered a delegate relationship,
something like "willMarkMispelledWordInRange:" ... where I could
choose to have it keep quiet instead.
On 10.5 and later, there is public API which you can override in your
NSTextView subclass:
- (void)setSpellingState:(NSInteger)value range:(NSRange)charRange;
// May be called or overridden to control setting of spelling and
grammar indicators. Values are those listed for
NSSpellingStateAttributeName. Calls the delegate method
textView:shouldSetSpellingState:range:.
or the delegate variant:
- (NSInteger)textView:(NSTextView *)textView shouldSetSpellingState:
(NSInteger)value range:(NSRange)affectedCharRange;
// Delegate only. Allows delegate to control the setting of
spelling and grammar indicators. Values are those listed for
NSSpellingStateAttributeName.
If you need to support 10.4, perhaps you can use a custom layout
manager which avoids setting the temporary spelling attributes for
ranges you don't wish to display misspellings for.
