Question

I want to store segmented control into the property list and also retrieve from plist too.
So how should I do that ?

Answer 1

Create a UISegmentControl Outlet in your viewcontroller

IBOutlet UISegmentedControl *mySegment;

Connect it to your UISegmentControl in Interface Builder

Add this IBAction method and wire it up in Interface Builder

- (IBAction) changeSegment: (id) sender {
    //save UISegment value in NSUserDefaults
    [[NSUserDefaults standardUserDefaults] setInteger:[sender selectedSegmentIndex] forKey:@"savedSegment"];
}

Restore the saved value when the view is loaded in viewDidLoad

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    self.mySegment.selectedSegmentIndex = [[NSUserDefaults standardUserDefaults] integerForKey:@"savedSegment"];
}
