Question

I’m having some trouble with displaying results from a datasource. This code will show a different (and correct) result in the console, but results in all kinds of random crap in the simulator.

(‘results’ is an NSMutableArray property for the class.)

-(void) handleSearchForKeywords: (NSString *) keywords {     [results removeAllObjects];     int r = rand() % 10;     for( int i = 0; i < r; i++ ) {         [results addObject:[NSString stringWithFormat:@'test %i: %@', i, keywords]];     }     [self reloadTheTable]; }  -(void) reloadTheTable {     NSLog( @'current array contents: %@', results );     [tableView reloadData]; }

I’m guessing that this might have something to do with memory retention of the array, or the strings in the array? I’m afraid I still haven’t got the hang of that.

[edit in response to Marc Bessey — I think everything here is your basic datasource methods]

-(NSInteger) tableView: (UITableView *) tableView numberOfRowsInSection: (NSInteger) section {     return [results count]; }  -(UITableViewCell *) tableView: (UITableView *) tableView cellForRowAtIndexPath: (NSIndexPath *) indexPath {     static NSString *SearchViewControllerCell = @'SearchViewControllerCell';     UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: SearchViewControllerCell];     if( cell == nil ) {         cell = [[[UITableViewCell alloc] initWithFrame: CGRectZero reuseIdentifier: SearchViewControllerCell] autorelease];         NSUInteger row = [indexPath row];         [cell setText:[results objectAtIndex:row]];     }     return cell; }

I don’t think the problem is in the code that you’ve posted. It’s more likely in the code that implements the datasource for your table view.
