Hi Bill,
I’m familiar with NSAttributedString and friends. I had thought that there was a higher level interface to it as it seems like a common thing to want to do.
Basically my ScrollView is just a scrolling line log similar to XCode’s NSLog window. I’m just appending an NSString to the Document View like this:
myTextView = [self documentView];
[[[myTextView textStorage] mutableString] appendString:theString];
Should I convert “theString” to a NSAttributedString and then set the attributes of this string, or set the attributes of [[[myTextView textStorage] mutableString] ? The reason I ask is because the TextView can get large and I’m not sure if setting the attributes each time would slow things down?
Thanks a lot,
All the Best
Dave

You should be looking at methods like NSMutableAttributedString's -setAttributes:range:. Basically, you start by creating a dictionary of formatting attributes, then you provide it to -setAttributes:range: with the range of characters to which you want those attributes applied. That's why they're called "attributed" strings -- they are strings with formatting attributes.

The "Paragraph Attributes" section of the Text Attribute Programming Topics is especially pertinent to your question, including its cross reference to the much more detailed Ruler and Paragraph Style Programming Topics.
