- (void)viewDidLoad
{
    [super viewDidLoad];

    // Button in center of Navigation Bar
    UISegmentedControl *button = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:LS(@"Save"), nil]];
    button.frame = CGRectMake(0, 0, 100, 30);
    button.center = self.view.center;
    button.momentary = YES;
    button.segmentedControlStyle = UISegmentedControlStyleBar;
    button.tintColor = [UIColor colorWithHue:0.6 saturation:0.33 brightness:0.69 alpha:0];
    [button addTarget:self action:@selector(saveToDocumentsClicked) forControlEvents:UIControlEventValueChanged];
    self.navigationItem.titleView = button;
}
