How to add data to last selected and default index using SegmentControl ios

I am using Segment Control. it contains two data. and one data is default and i need to display default in segment.

I am setting default data like this:

- (void)awakeFromNib 
{
    [super awakeFromNib];
    [priceOptionSeg addTarget:self action:@selector(segmentedControlValueDidChange:) forControlEvents: UIControlEventValueChanged];
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated 
{
    [super setSelected:selected animated:animated];
    [self assignDO:priceList];
}

- (void)assignDO:(NSMutableArray *)inputList 
{
    for (int x = 0; x < inputList.count; x++) 
    {
        if (tempDO.price_is_default == YES) 
        {
            [priceOptionSeg setSelectedSegmentIndex:x];
            NSLog(@"%ld",(long) priceOptionSeg.selectedSegmentIndex);
        }
    }
}

I am mananing index like this way:

- (void)segmentedControlValueDidChange:(UISegmentedControl *)segment
{
    switch (segment.selectedSegmentIndex) 
    {
        case 0:
            NSLog(@"First was selected");
            break;

        case 1:
            NSLog(@"Second was selected");
            break;

        default:
            break;
    }
}

I am able to add default value in segment control. I can change values in segment. suppose I select 2nd segment but when I move to next controller and back to my controller segment is at first index.i want like if i move to next controller but when I come at my controller. last selected segment should be there what to do

In your ViewController.h declared int like

@property(nonatomic,assign)int selectedIndex;

in ViewDidLoad assign the default value

self.selectedIndex = 0;

in CellForRowAtIndexpath selected index

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    //Create you custom class cell here
    ..
    [cell.priceOptionSeg addTarget:self action:@selector(segmentedControlValueDidChange:) forControlEvents: UIControlEventValueChanged];
    [cell.priceOptionSeg setSelectedSegmentIndex:self.selectedIndex];
    ..
}

and add the value change action of segment in same view controller 

- (void)segmentedControlValueDidChange:(UISegmentedControl *)segment
{
    switch (segment.selectedSegmentIndex) 
    {
        case 0:
            self.selectedIndex = 0;
            break;

        case 1:
            self.selectedIndex = 1;
            break;

        default:
            break;
    }
}

From your existing Cell SubClass remove Following line 

[priceOptionSeg addTarget:self action:@selector(segmentedControlValueDidChange:) forControlEvents: UIControlEventValueChanged];
