You can easily sort a NSMutableArray:

NSSortDescriptor *nameSort = [NSSortDescriptor sortDescriptorWithKey:@"Name" ascending:YES];
[lstAirports sortUsingDescriptors:[NSArray arrayWithObject:nameSort]];

IN viewWillAppear

NSSortDescriptor *aSortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"Name" ascending:YES];
[app.lstAirports sortUsingDescriptors:[NSArray arrayWithObject:aSortDescriptor]];
[aSortDescriptor release];

You need to order the array from which you populate the table view, in this case app.lstAirports. This will teach you how to do it.

Sort your array using NSSortDescriptor

NSSortDescriptor * sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"key_name" ascending:YES];
[yourArray sortUsingDescriptors:[NSArray arrayWithObject:sortDescriptor]];
