    <p>I am stuck on a EXC_BAD_ACCESS” crash within my dealloc of a table view controller. The crash occurs when releasing an NSMutableArray that was given a retain property. I have a second NSMutableArray that was also given a retain property, but it's release does not cause a crash. Please take a look at the following code to see if I am overlooking something about memory management. Thanks.</p> <p>In my header file, I have the following:</p> <pre><code>@interface selectSourcesTableViewController : UIViewController &lt;UITableViewDelegate, UITableViewDataSource&gt; { NSMutableArray *selectedNames; NSMutableArray *selectedAvailability; } @property (retain, nonatomic) NSMutableArray *selectedNames; @property (retain, nonatomic) NSMutableArray *selectedAvailability; </code></pre> <p>In my implementation, I have the following:</p> <pre><code>@implementation selectSourcesTableViewController @synthesize selectedNames; @synthesize selectedAvailability; - (void)viewDidLoad { NSArray *names = [selectedSourceFileContent objectForKey:@"selectedNames"]; selectedNames = [[NSMutableArray alloc] initWithObjects: nil]; NSArray *availability = [selectedSourceFileContent objectForKey:@"selectedAvailability"]; selectedAvailability = [[NSMutableArray alloc] initWithObjects: nil]; for (int i=0; i &lt; [names count]; i++) { NSString *aName = [names objectAtIndex:i]; [selectedNames addObject: aName]; NSString *anAvailability = [availability objectAtIndex:i]; [selectedAvailability addObject: anAvailability]; } } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: kCellIdentifier]; ... for (int i=0; i &lt; [selectedNames count]; i++) { if ([contentForThisRow isEqualToString:[selectedNames objectAtIndex:i]]) { cell.accessoryType = UITableViewCellAccessoryCheckmark; } } } - (void)dealloc { [super dealloc]; [selectedNames release]; [selectedAvailability release]; } </code></pre> <p>The code shown above shows the only uses of these two arrays.</p> <p>So, nothing bad happens when selectedNames is released, but I get a EXC_BAD_ACCESS crash when selectedAvailability is released.</p> <p>One last observation. There is no crash the very first time I run this code after launching xcode. Thereafter, it crashes every time I rerun the app.</p> <p>Any thoughts?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
