Hello,
Take a look at the NSTextView delegate method
shouldChangeTextInRange:replacementString:
The replacementString parameter will be blank (@"") on deletes, nil
for attribute changes, and have a string on inserts or replacements of
existing text.
This method is called before the actual change, so you can use the
range passed in to determine whether an attachment will be deleted,
then act on that information in the didChangeText method.
hope that helps,

Hi,
I am using a NSTextView and i programatically insert images as
NSTextAttachments in the textView. These attachments are shown in an
NSTextAttachmentCell by the NSTextView.
I want to do some background processing just before the user deletes
the image from the textView. This can happen if the user simply hits
the delete key or replaces the image with some string.
How can i detect if an NSTextAttachment or it's NSTextAttachmentCell
is about to be removed from the textView?
Any help would be appreciated.
