Hello all,
I have a view-based table in which there are four distinct row types,
representing distinct object types which may appear. The tableRowViews are in
the nib and represented in the code here as xxxCellView entities.
- (CGFloat)tableView:(NSTableView *)tableView heightOfRow:(NSInteger)row {
id obj = [_content objectAtIndex:row];
if([obj isKindOfClass:[RSPostalAddress class]]) {
return self.postalCellView.bounds.size.height;
}
else if([obj isKindOfClass: [RSEmailAddress class]]) {
return self.emailCellView.bounds.size.height;
}
else if([obj isKindOfClass: [RSPhoneNumber class]]) {
return self.phoneCellView.bounds.size.height;
}
else { // note field
return self.notesCellView.bounds.size.height;
}
}
My problem is that on first pass, this code returns quite sane and reasonable
results: the manually set sizes of the prototype tableRowViews. However on
second pass, it goes insane: 132.0 becomes 266.0, 28.0 becomes 118.0, 104.0
becomes 210.0 ... And the next thing the -tableView:heightOfRow: does is throw
it's brain in the air and gives up …. :P

My expectation is that I ought to be able to clear the table (iterating through
the rows and applying -removeRowsAtIndexes:withAnimation: to discard the
present rowViews, and start clean with the next record to be displayed,
generating new rowViews as needed (because the number of component elements
(phone numbers/email addresses/etc) will vary from one record to the next).
I have no iterator code running at the time this error occurs, so I suspect I
have failed to correctly setup some aspect of the tableView/rowView mechanics.
Does anything suggest itself to anyone ?
Hopefully,
Erik
