You could store the state as a member variable, then update the UI in viewWillAppear:animated:. For example, in FlipsideViewController.h file, declare a member variable called switchIsOn:

@interface FlipsideViewController : UIViewController {
    BOOL switchIsOn;
    // Other member variables here
}

@property (nonatomic) BOOL switchIsOn;

Then in FlipsideViewController.m:

@synthesize switchIsOn;

-(void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    [self.switch setOn:self.switchIsOn animated:NO];
}

You can set the value of self.switchIsOn in response to the switch being toggled. e.g. create a method like this:

-(IBAction)handleSwitch:(id)sender {
    self.switchIsOn = self.switch.on;
}

and then bind that method to the switch's Value Changed event.

Hope this helps.
