POEXEC_BAD_ACCESS upon re-loading a UIViewController containing a UITableView
text
Body
copied!<p>I get an EXEC_BAD_ACCESS when executing the following steps:</p> <p><strong>STEP 1: Click on "Scores" button from a Main Menu:</strong> This Removes the Menu (UIView), and loads the Scores (UIView) which subsequently initiates the process of populating a UITableView with values. No problems here.</p> <pre><code> self.viewController4 = [[ScoresViewController alloc] initWithNibName:@"ScoresViewController" bundle:nil]; [window addSubview:viewController4.view]; [viewController.view removeFromSuperview]; NSLog(@"LOADING SCORES SCREEN"); </code></pre> <p><strong>STEP 2: Click on "menu" button from the Scores Screen:</strong> This Removes the Scores (UIView), and loads the Menu (UIView) again. No problems here.</p> <pre><code>self.viewController = [[MainMenuViewController alloc] initWithNibName:@"MainMenuViewController" bundle:nil]; [window addSubview:viewController.view]; [viewController4.view removeFromSuperview]; NSLog(@"Loading MAIN MENU"); </code></pre> <p><strong>STEP 3: Click on the "Scores" button again from the Main Menu:</strong> Again, this Removes the Menu (UIView), and loads the Scores (UIView) which subsequently initiates the process of populating a UITableView with values. <strong><em>Problematic!</em></strong></p> <p>The application crashes before displaying the Score Screen (UIView). Using the debugger I traced the problem to the single line of code: <strong><em>cell.text = [self->theScoresArray objectAtIndex:indexPath.row];</em></strong> appearing in the below routine:</p> <pre><code> - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [theTable dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease]; } cell.text = [self->theScoresArray objectAtIndex:indexPath.row]; return cell; } </code></pre> <p>Could this be a problem with the indexPath object not being properly released the first time? Any insight would be helpful. Thanks for your valuable time.</p>
