Mostrar una vista modal de izquierda a derecha

Para abrir la ventana
CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromRight;
[self.view.window.layer addAnimation:transition forKey:nil];
[self presentModalViewController:viewCtrl animated:NO];

Para cerrar la ventana cambiamos la llamada:

[self presentModalViewController:viewCtrl animated:YES];

Por

CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromRight;
[self.view.window.layer addAnimation:transition forKey:nil];

[self presentModalViewController:viewCtrl animated:NO];

Poner una imagen en un control UIPickerView

Hay que utilizar este metodo en lugar del que solo devuelve el texto.

– (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view
{
NSString *t=@»»;
UIView *tmpView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 280, 32)];
UILabel *channelLabel = [[UILabel alloc] initWithFrame:CGRectMake(30, 0, 250, 25)];
t=def.funciones[row];
UIImage *img = [UIImage imageNamed:@»Nombredelaimagen»];
UIImageView *temp = [[UIImageView alloc] initWithImage:img];
temp.frame = CGRectMake(0, 0, 25, 25);
[tmpView insertSubview:temp atIndex:0];
channelLabel.text = @»El texto que quieres»;
[channelLabel adjustsFontSizeToFitWidth];
channelLabel.textAlignment = UITextAlignmentLeft;
channelLabel.backgroundColor = [UIColor clearColor];
[tmpView insertSubview:channelLabel atIndex:0];

return tmpView;

}

Como detectar el dispositivo y el idioma

Para detectar el idioma:
NSString *locale = [[NSLocale currentLocale] localeIdentifier]; // en_US

Para detectar el dispositivo:
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
if (altopantalla == 568)
{
//es un iphone 5

}
else
{
//es un iphone

}
} else {
//es un ipad
}
