copied!<p>I've a problem with an array. There's an array with some objects of the class Car in my CarViewController:</p> <p>...Car.h</p> <pre><code>@interface Car : NSObject @property (nonatomic, strong) NSString *name; </code></pre> <p>..and Car.m</p> <pre><code>- (void)encodeWithCoder:(NSCoder *)coder; { [coder encodeObject:name forKey:@"name"]; } - (id)initWithCoder:(NSCoder *)coder; { self = [[Car alloc] init]; if (self != nil) { name = [coder decodeObjectForKey:@"name"]; } return self; } </code></pre> <p>and CarViewController</p> <pre><code> Car *car1 = [Car new]; car1.name = @"A1"; ... cars = [NSArray arrayWithObjects: car1, car2, ..., nil]; </code></pre> <p>But when I now try to have access to this array in NewViewController there is a problem:</p> <pre><code>- (IBAction)btn:(id)sender { UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Storyboard" bundle:nil]; CarViewController *vc = (CarViewController *)[storyboard instantiateViewControllerWithIdentifier:@"CarVC"]; Car *car = [vc.cars objectAtIndex:0]; NSLog(@"%@", car.name); } </code></pre> <p>But in the log is just written that <strong>car.name = (null)</strong>. Thanks in advance to your effort.</p> <p><strong>UPDATE</strong>:</p> <pre><code>- (IBAction)btn:(id)sender { UINavigationController *nav = self.tabBarController.viewControllers[1]; CarViewController *vc = nav.topViewController; Car *car = [vc.cars objectAtIndex:0]; NSLog(@"%@", car.name); } </code></pre> <p>I've tried something (thanks to <strong>rdelmar</strong> for his effort), but the result is still the same.</p>
