Why Isn't NSUserDefaults working with my UISwitch

I'm trying to setup a UISwitch that is off by default until the user turns it on. However it is showing ON by default now.

AppDelegate's didFinishLaunching:

NSString *testValue = [[NSUserDefaults standardUserDefaults] stringForKey:@"pinCodeSwitch"];
if (!testValue) {
    // since no default values have been set, create them here
    [[NSUserDefaults standardUserDefaults] setBool:NO forKey:@"pinCodeSwitch"];
    [[NSUserDefaults standardUserDefaults] synchronize];
}

VC's viewDidAppear:

UISwitch* testSwitch = [[[UISwitch alloc] init] autorelease];
if ([[NSUserDefaults standardUserDefaults] boolForKey:@"pinCodeSwitch"]) {
    [testSwitch setOn:NO animated:NO];
}
self.pinCodeSwitch = testSwitch;

Method to save BOOL when UISwitch's value changed:

- (IBAction)pinCodeSwitchChanged:(id)sender
{
    [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"pinCodeSwitch"];
    BOOL test = [[NSUserDefaults standardUserDefaults] boolForKey:@"pinCodeSwitch"];
}

You're not getting to set the switch since you set 'pinCodeSwitch' to NO. It skips the if statement. Change it to:

if (![[NSUserDefaults standardUserDefaults] boolForKey:@"pinCodeSwitch"])

(Negate your test), then the switch will turn off.

you can specify this value in the Interface Builder by the "STATE" value to OFF. and after that save the switch value by applying this code: 

[YourUiSwitch setOn:NO animated:YES];
[[NSUserDefaults standardUserDefaults]setValue:YourUiSwitch forKey:@"youruiswitch"];
[[NSUserDefaults standardUserDefaults]synchronize];

and when the view did load comes load it from the defaults like this:`YourUiSwitch = 

[[NSUserDefaults standardUserDefaults]valueForKey:@"youruiswitch"];`

GOOD LUCK BUDDY!
