UISegmentedControl insert animation completion handler

UISegmentedControl has a method:

- (void)insertSegmentWithTitle:(NSString *)title atIndex:(NSUInteger)segment animated:(BOOL)animated

If I set the animated to true, is there a way for me to find out when the animation is completed(i.e. completion handler, animation delegate, duration)?

Some time back I also faced this kind to problem to check animation complete of UITableView, I have found one very useful post - Animation End Check

You can also use this approach for your use, Before posting this answer I have checked this on segment control and it is working well. You might use like - 

- (void)viewDidLoad {
    [super viewDidLoad];

    NSArray *itemArray = [NSArray arrayWithObjects: @"One", @"Two", @"Three", nil];

    self.segmentedControl = [[UISegmentedControl alloc] initWithItems:itemArray];
    self.segmentedControl.frame = CGRectMake(10, 100, 250, 50);
    self.segmentedControl.selectedSegmentIndex = 0;
    [self.view addSubview:self.segmentedControl];
}


- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];

    [CATransaction begin];
    [CATransaction setCompletionBlock:^{
        NSLog(@"Animation finished");
    }];

    [self.segmentedControl insertSegmentWithTitle:@"Four" atIndex:3 animated:YES];
    [CATransaction commit];
}

This works as the default animations use CALayer animations and here we define one implicit CATransaction.
