An Example:
mTable = member instance for your TableView
mData = member array which provides the data-objects.
Put the following code at a place where your table and data-source array is
initialized. Like in awakeFromNib: method.
Here I'm sorting on key "name", Change it to whatever key you have in your
data-object on which you want to do the sorting. You can do the same thing
from IB as well, then you don't have to write the following code.
[mTable setSortDescriptors:[NSArray arrayWithObject:
[[[NSSortDescriptor alloc]initWithKey:@"name" ascending:YES
selector:@selector(caseInsensitiveCompare:) ]autorelease]]];
[mData sortUsingDescriptors:[mTable sortDescriptors]];
Now implement the following delegate for NSTableView:
- (void)tableView: (NSTableView *)aTableView
sortDescriptorsDidChange: (NSArray *)oldDescriptors
{
[mData sortUsingDescriptors: [aTableView sortDescriptors]];
[mTable reloadData];
}
