Help!!!
My text program is having errors, when I attempt to reflow the text,
but only the second time!
Let me explain. My application displays text in 3 column format on
mulitble pages, depending on the length of the text. So I create a text
storage and layout objects, then on the fly, create container/text view
pairs to add to the layout. Each column is 1/3 of the page wide, and
one page long. After I add pair using addTextContainer, I call
glyphRangeForBoundingRect to have the text flow into the containers. I
receive the didCompleteLayoutForTextContainer method, and keep track
of when the text have enough containers/text views so to stop adding
new pairs to the layout. Everything works perfectly the first time
window is displayed. Then user changes a setting, and the text is
reformed. I remove the layout object from text storage, and release it
(which releases all the containers/text views). Then I create new
layout, and start filling in containers/text views. This is same code I
use to fill in first time. On the second pair of containers/text views,
when I call addTextContainer to add container to layout, I get the
following error:
2002-10-31 00:01:18.374 MyApp[3503] *** NSRunStorage,
_NSBlockNumberForIndex(): index (793) beyond array bounds (0)
2002-10-31 00:01:18.420 MyApp[3503] Exception raised during background
layout: *** NSRunStorage, _NSBlockNumberForIndex(): index (793) beyond
array bounds (0)
2002-10-31 00:01:18.428 MyApp[3503] *** NSRunStorage,
_NSBlockNumberForIndex(): index (793) beyond array bounds (0)
The funny thing is this code worked for awhile. As always, I was
messing with code to have correct appearance, and something broke!
Anyone have any suggestions or comments?
Thanks,
Steve Sheets
