I'm trying to use an NSTextView to display the output of a shell
script, but when my script outputs too much data, too quickly (on
the order of a dozen lines nearly simultaneously), my app gives up
with a pinwheel. I'm using an NSPipe to get the data,
readInBackgroundAndNotify to know when to put it in my view, and
[[[myTextView] textStorage] appendAttributedString:] to do the
actual view updating. After a while, when my view starts to contain
thousands of lines or so, attempting to do any scrolling causes a
pinwheel for some length of time. Any ideas on how I could do this
better?
Have you tried using Shark or Spin Control to find out why this is
happening?
