A view can only be associated with at most one view controller at a time (UISegmentedControl)

Question

Hello The error occurs in the simulator on iOS 6.

Terminating app due to uncaught exception 'UIViewControllerHierarchyInconsistency', reason: 'A view can only be associated with at most one view controller at a time! View <UIView: 0xa3ae880; frame = (0 0; 320 367); autoresize = W+H; layer = <CALayer: 0xa3ae8e0>> is associated with <SearchHotelsViewController: 0xa3a6a20>. Clear this association before associating this view with <SecondViewController: 0xa1a9e90>.'

Initialization code

UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"Поиск туров", @"Выбор отеля", nil]];  segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar; self.navigationItem.titleView = segmentedControl;  [segmentedControl addTarget:self action:@selector(changeSegments:) forControlEvents:UIControlEventValueChanged]; segmentedControl.selectedSegmentIndex = 0; self.navigationItem.title = [segmentedControl titleForSegmentAtIndex:segmentedControl.selectedSegmentIndex]; [self setView:searchTours];  SearchHotelsViewController *searchHotelsController = [[SearchHotelsViewController alloc] initWithNibName:@"SearchHotelsViewController" bundle:[NSBundle mainBundle]]; selectHotels = searchHotelsController.view; 

App crashes when selected == 1 is true

-(void)changeSegments:(id)sender {     NSInteger selected = [sender selectedSegmentIndex];     if (selected == 0) {         [self setView:searchTours];     }     if (selected == 1) {         [self setView:selectHotels];     }     self.navigationItem.title = [sender titleForSegmentAtIndex:selected]; } 

I cannot understand where the problem is.

Make sure your ViewController does not contain another view controller object. For example if your main view controller has a tableview, do not put the UITableViewController with in. It this used to pass in iOS 5, but in iOS 6 they will not allow this.
