Subclass ScrollingNavigationViewController and implement ScrollingNavigationDelegate.

Call setLabelFont to set the font of labels at navigation bar.

 [self setLabelFont:[UIFont fontWithName:@"HelveticaNeue-Bold" size:18.0f]];

```
Call setUnselectedLabelColor to set the color of unselected label.
```
 [self setUnselectedLabelColor:[UIColor lightTextColor]];
```
Set delegate to self.
```
 self.delegate = self;
```
Intialize navigationTitles (property of ScrollingNavigationViewController of type NSMutableArray) to set the titles at navigation bar.
```
self.navigationTitles = [[NSMutableArray alloc] initWithObjects:@"Home",@"Personal",@"Office", @"one more", nil];
```
Implement delegate method labelSwitchedAtIndex to know the highlighted option and take appropriate action in your View Controller.This method receives the current index value of the highlighted option.
```
-(void)labelSwitchedAtIndex:(NSUInteger)index{
  _selectedLabel.text = [self.navigationTitles objectAtIndex:self.selectedLabelIndex];
}
```
