Dear list,
I have an application which uses NSTextStorage objects to provide multiple
views of the content of files. In principle, everything seems to be working
fine; I can have multiple views of the same document and edit just fine. In
most cases the text storage is initialized with some content, but in the case
that the text storage is initialized with an empty string, I get exceptions the
first time an attempt is made to insert a string using a NSTextView (calls to
insertText:). The code that initializes the text storage is (simplified):
textStorage = [[NSTextStorage alloc] initWithString:str];
// Add a main layout manager
NSLayoutManager *layoutManager = [[NSLayoutManager alloc] init];
[textStorage addLayoutManager:layoutManager];
// Now add the container to the layout manager
[layoutManager addTextContainer:textContainer];
// Clean up
[textContainer release];
[layoutManager release];
[str release];
The exception I get is shown below. So as long as 'str' has at least one
character in it, then I don't get the problems. I can then delete all in the
text view and then type and all is well - just if I start from an empty text
storage ...
Any advice or clues would be gratefully received.
Best wishes,
Martin
p.s. the implementation of insertText: doesn't do much, and removing this
method from the text view subclass doesn't fix the problem.
