hi,

I am making a booking page. I have included 3 pickers in it. I have included all the delegates required for the pickers to work but it wont rotate.

I have enabled user interaction and multitouch in the nib file. Here is my code. Please help me. :(

@interface ChooseContactsFrom : UIViewController { IBOutlet UIPickerView *statePickup; IBOutlet UIPickerView *paymentMethodPickup; IBOutlet UIDatePicker *expiryDatePickup;

IBOutlet UIView *statePickupView; IBOutlet UIView *paymentMethodPickupView; IBOutlet UIView *expiryDatePickupView;

}

• (void)viewDidLoad { self.title = @"Choose Contacts"; //Fill in the states name/ stateArray = [[NSArray alloc]initWithObjects:@"",nil]; paymentModeArray = [[NSArray alloc] initWithObjects:@"Credit Card", @"Cash",@"Account",@"Voucher",@"Debit Card", nil];

  paymentMethodPickup.frame = CGRectMake(0.0, 44.0, paymentMethodPickup.frame.size.width, paymentMethodPickup.frame.size.height); paymentMethodPickup.userInteractionEnabled = YES; paymentMethodPickup.multipleTouchEnabled = YES; paymentMethodPickupView.frame = CGRectMake(0.0, 210.0, paymentMethodPickupView.frame.size.width, paymentMethodPickupView.frame.size.height);

  statePickup.frame = CGRectMake(0.0, 44.0,statePickup.frame.size.width, statePickup.frame.size.height); statePickupView.frame = CGRectMake(0.0, 210.0, statePickupView.frame.size.width, statePickupView.frame.size.height); stateArray = [[NSArray alloc] initWithObjects:@"state1", @"state2", @"state3", @"state4", @"state5", @"state6", @"state7", @"state8", @"state9", @"state10", nil];

  expiryDatePickup.frame = CGRectMake(0.0, 44.0, expiryDatePickup.frame.size.width, expiryDatePickup.frame.size.height); expiryDatePickupView.frame = CGRectMake(0.0, 210.0, expiryDatePickupView.frame.size.width, expiryDatePickupView.frame.size.height);

  [super viewDidLoad]; }

-(IBAction)back:(id)sender { [self dismissModalViewControllerAnimated:YES]; }
