    copied!<p>My iPhone application blows up when it accesses an instance variable from within one of the UITableView delegate methods. I think I'm retaining it so I do not understand why I can't access it without a problem.</p> <p>Here's my .h file</p> <pre><code>#import &lt;Foundation/Foundation.h&gt; #import "AlertSummaryCell.h" #import "AlertDetailViewController.h" @interface AlertSummaryTableViewController : UITableViewController { NSDictionary *alerts; NSString *alertKind; } </code></pre> <p>@property (nonatomic, retain) NSDictionary *alerts; @property (nonatomic, retain) NSString *alertKind;</p> <p>@end</p> <p>In my .m, the application dies at the first NSLog call:</p> <pre><code>- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { NSLog(@"AlertSummaryTableViewController.numberOfRowsInSection entered"); NSLog(@" alerts description = %@", [alerts description]); // To know how many alert summaries we have, get the value for count out of the input dictionary int theCount = [[alerts objectForKey:@"count"] intValue]; NSLog(@" Going to return %d",theCount); return theCount; } </code></pre> <p>What am I missing???</p> <p>There's no problem at all in the viewDidLoad method:</p> <pre><code> - (void)viewDidLoad { NSLog(@"AlertSummaryTableViewController.viewDidLoad entered"); NSLog(@" alerts description = %@", [alerts description]); // We want the View title to include the alert count // To know how many alert summaries we have, get the value for count out of the input dictionary int theCount = [[alerts objectForKey:@"count"] intValue]; // Now construct the title text and set our views title to it NSString *myTitle = [[NSString alloc] initWithFormat:@"%@ Alerts (%d)",alertKind,theCount]; [self setTitle: myTitle]; // Memory cleanup [myTitle release]; [super viewDidLoad]; } </code></pre>
