That's what I was afraid of. What I'm doing is cycling through the

attributes of every character. Damn.
It's often more efficient to iterate through the attributes, because
they are typically unchanged for long runs, and the APIs return them
per run. You can get both attachments and links by iterating through
the attributes, looking for the attachment and link attributes.
Attribute fixing makes sure that the attachment attribute is not
applied to non-attachment characters.

Good suggestion. Since attributeRuns is so thinly documented, I have
one other question. Given that I've got my array of attribute runs, I'm
iterating through them, I've found a run with a link attribute, like
so:
NSArray *attRuns = [[entryView textStorage] attributeRuns];
int runCount = [attRuns count];
int runs = 0;
for (runs = 0; runs < runCount; runs++) {
NSRange range;
NSAttributedString *localAtts = [attRuns objectAtIndex:runs];
if ([localAtts attribute:NSLinkAttributeName atIndex:0
effectiveRange:&range] != nil) {
NSLog([localAtts description]); <=just checking
}
}
Is there a way for me to get the range of localAtts within [entryView
textStorage]? -rangeOfString:[localAtts string] won't be much use,
because it might pounce on a different occurrence of that substring.
(What I'm trying to do is insert html tags in the string, so I need to
be able to replace, say, "ADC Home" with "<a
href=\"
http://developer.apple.com/\";>ADC Home</a>".)
