Hi,
I am writing a small application that reads a data file, it then determines
the number of columns to add to a tableview, builds a represention of the
file and then adds the columns to a table view that was created with no
columns.
The data shows up in the table automagically.
The problems appear when I try to repeat the process with another file...
Application crashes via a seg violation.
I enter the routine and delete the columns from the table view using many
variations of code similar to:
// Try to determine if we have been here before if so then clean up...
colArray =[NSArray arrayWithArray: [tableView tableColumns]];
NSLog(@"tmp array %@",colArray);
if([colArray count]) {
for(i=0; i< [tmpArray count] ; i++){
[tableView removeTableColumn: [tmpArray objectAtIndex:i]];
}
NSLog(@"Finished releasing columns");
// [colArray release];
// [tableView tile];
// NSLog(@"Released tmpArray");
}
I then get the file name from the user and build the data array.
I then add new columns
Of course the data array is used in the tableView delegate methods.
Taint clear to me what a suitable protocol might be for switching the number
of columns and supplying an data source that reflects the new file.
Thanks for any insight...
