estoy recibiendo el mensaje de error que no puedo entender por qué su suceso, porque no estoy usando cualquier UIImageView. A veces recibo el mismo error pero es un CALayer?!?selector no reconocido enviado a la instancia
Vale la pena mencionar también que tengo 2 nibs y 2 controladores y un controlador de base donde reside el código.
EDIT:
Ésta es la estructura de mi proyecto
MainViewController & su punta - HomeViewController en punta
MainViewController-paisaje & su punta - HomeViewController-paisaje en punta
HomeViewControllerBase - sin punta - Clase base donde todos o existe el código de configuración de artículos y utlets. - Las dos clases secundarias utilizan los puntos de venta a continuación. - Las salidas están vinculadas a los controles en cada una de las puntas principales.
HomeViewController - hereda de HomeViewControllerBase
HomeViewController-paisaje - hereda de HomeViewControllerBase
Así qué está sucediendo es que la clase niño está tratando de dealloc su clase base (que tiene todos los puntos de venta en el mismo) . Lo he diseñado de esta manera para evitar la duplicación de código en los diferentes viewcontrollers de orientación.
@implementation MainViewController
- (void)orientationChanged:(NSNotification *)notification

UIDeviceOrientation deviceOrientation = [UIDevice currentDevice].orientation;
if (UIDeviceOrientationIsLandscape(deviceOrientation) && !isShowingLandscapeView)

animated:YES];
isShowingLandscapeView = YES;
}
else if (UIDeviceOrientationIsPortrait(deviceOrientation) && isShowingLandscapeView)

isShowingLandscapeView = NO;
}

Una cosa que estoy notando es que a tomar la contentSize del ScrollView 150 veces algo mientras se está creando 151 botones. – onnoweb
