Hi Shane,
The way I’ve been doing this is to keep hold of my own text finder in my
NSTextView subclass:
self.textFinder = [[NSTextFinder alloc] init];
then to set it up like this:
[self.textFinder setClient:self];
[self.textFinder setFindBarContainer:[self enclosingScrollView]];
[self setUsesFindBar:YES];
[self setIncrementalSearchingEnabled:YES];
then when I want to switch out the text (because I’m changing the underlying
text storage) I do
[self.textFinder cancelFindIndicator];
[self.textFinder noteClientStringWillChange];
Unfortunately I still get reports of crashes similar to what you report. I’ve
even made a test project that shows that doing this doesn’t fix the problem. On
switching the text storage, the find bar stays visible (even though I’m calling
-cancelFindIndicator, probably because this isn’t supposed to hide the find
bar, and I don’t know how to do that), and hitting enter again to get the next
search result shows a false result. If that result would be out of bounds of
the new text string, then a crash will happen, of course.
I’m happy to share my test project, if you are interested. And I’d be really
happy to hear about a way to deal with this. I’ve been in touch with Apple and
even provided my test project, but that was a long time ago, and still the
issue remains. So either there is a bug, or I’m doing something wrong in
swapping out the text storage for the text view.
Cheers,
Martin
