Thanks Finlay!
OK, I dove into NSTextView. It doesn't have much to
say about this, but luckily there is some info to be
gleaned from the TextEdit project sources in the
examples folder.
I got the following code to work:
- (IBAction)TestButton:(id)sender
{
NSURL *theURL;
NSURL *baseURL;
NSTextStorage *myTextStorage = [myTextView
textStorage];
NSMutableDictionary *options =
[NSMutableDictionary dictionary];
NSDictionary *docAttrs;
BOOL success;
baseURL = [NSURL URLWithString:
@"file:///Users/jra/test/"];
theURL = [NSURL URLWithString:
@"file:///Users/jra/test/index.html"];
[options setObject:baseURL
forKey:@"BaseURL"];
[myTextStorage beginEditing];
[myTextStorage readFromURL:theURL
options:options
documentAttributes:&docAttrs];
[myTextStorage endEditing];
}
It works great for very simple HTML. BUT, when I start
to get fancy (not really fancy, just not using really
simple HTML) and the thing just hangs. It certainly
didn't work with any of the web pages I had sitting
around to test it with. I'd be worried about sending
arbitrary - though perfectly legal HTML at it.
And I tried using an "
http://..."; URL instead of a
"file://..." URL and it went into orbit as well.
This all looks like it *should* be useful, but there
are too many quirks and gotchas. That and the fact
that there is absolutely no documentation for it.
One more reason to go back to Swing/Java (I'm getting
*this* close to chucking Cocoa and sticking with Swing
and Java).
