How to programmatically add a UISegmentedControl to a container view

Question

How would I define the frame for a UISegmentedControl? I would like the segmented control to appear at the bottom of a container view i.e UI

Answer 1

Step 1. Create segment control with index values

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"common-bg.jpg"]];
    [self.navigationItem setHidesBackButton:YES];

    //-- For creating segment control in navigation bar
     UISegmentedControl *mainSegment = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"Back", @"Month", @"Year", @"Home", nil]];
    [mainSegment setSegmentedControlStyle:UISegmentedControlStyleBar];
    mainSegment.frame = CGRectMake(0,0, 400, 43);
    self.navigationItem.titleView = mainSegment;
    mainSegment.selectedSegmentIndex = 1;
    [mainSegment addTarget:self action:@selector(mainSegmentControl:) forControlEvents: UIControlEventValueChanged];
    [self.view addSubview:mainSegment];
    //--**--

}

Step 2. Create subview

- (void)mainSegmentControl:(UISegmentedControl *)segment
{

    if(segment.selectedSegmentIndex == 0)
    {
        // action for the first button (Current or Default)
    }
    else if(segment.selectedSegmentIndex == 1)
    {
        // action for the second button 
    }
    else if(segment.selectedSegmentIndex == 2)
    {
        // action for the third button 
    } 
    else if(segment.selectedSegmentIndex == 3)
    {
        // action for the fourth button 
    }
}
