    copied!<p>I have 3 classes</p> <p>First -> MainViewController:</p> <pre><code>@interface MainViewController : UIViewController { UtilityBadah *utility; } @property (strong, nonatomic) NSManagedObjectContext *managedObjectContext; - (IBAction)option; @end @implementation MainViewController @synthesize managedObjectContext = _managedObjectContext; (IBAction)option{ UtilityBadah *util = [[UtilityBadah alloc] initWithContext:_managedObjectContext]; OptionController *ovc = [[OptionController alloc] init]; ovc.util = util; ovc.managedObjectContext = _managedObjectContext; [self.navigationController pushViewController:ovc animated:YES]; [util release]; [ovc release]; } @end </code></pre> <p>Second -> UtilityBadah:</p> <pre><code>@interface UtilityBadah : NSObject { NSManagedObjectContext *managedObjectContext; NSString *kitab; NSString *lagu; NSString *font; NSString *sizefont; } @property (nonatomic, retain) NSManagedObjectContext *managedObjectContext; @property (nonatomic, retain) NSString *kitab; @property (nonatomic, retain) NSString *lagu; @property (nonatomic, retain) NSString *font; @property (nonatomic, retain) NSString *sizefont; (id) initWithContext: (NSManagedObjectContext *) context; @end @implementation UtilityBadah @synthesize managedObjectContext; @synthesize kitab; @synthesize lagu; @synthesize font; @synthesize sizefont; -(id) initWithContext: (NSManagedObjectContext *) context { NSError *err; NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *enDesc = [NSEntityDescription entityForName:@"OptionDB" inManagedObjectContext:context]; [request setEntity:enDesc]; NSArray *arrData = [context executeFetchRequest:request error:&amp;err]; for (OptionDB *data in arrData) { lagu = data.lagu; kitab = data.kitab; font = data.font; sizefont = data.sizefont; } return self; } </code></pre> <p>Thrid -> OptionController:</p> <pre><code>@interface OptionController : UIViewController{ NSManagedObjectContext *managedObjectContext; UtilityBadah *util; } @property (nonatomic, retain) NSManagedObjectContext *managedObjectContext; @property (nonatomic, retain) UtilityBadah *util; @end (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { bla..bla.. NSLog(@"value is %@",self.util.kitab); cell.textLabel.text = [listData objectAtIndex:row]; return cell; } </code></pre> <p>i wonder why this piece of code:</p> <pre><code>NSLog(@"value is %@",self.util.kitab); </code></pre> <p>cause an error "Receiced signa: "EXC_BAD_ACCESS" ? i wonder ther somthing wrong the way i passed the UtilityBadah object from MainViewController to my OptionController.</p> <p>Many thanks for any answer.</p> <p>P.S what is wrong with my xcode 4.2 error information, why it always show "Program received signal: "EXC BAD ACCESS"? cant it be informative?</p>
