ios remove sub view from another controller

I added a sub view from controller A. Now in controller B which is the subview controller, how can I reload view A when the user is done with B? My codes of adding subview:

ChangeProfileImage *changeProfileImage =[[ChangeProfileImage alloc] init];  
    changeProfileImage.modalPresentationStyle = UIModalPresentationFormSheet;
    changeProfileImage.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
    changeProfileImage.view.frame = CGRectMake(50, 50, 300, 300);  
    UIView *dimBackgroundView = [[UIView alloc] initWithFrame:self.view.bounds];
    dimBackgroundView.backgroundColor = [[UIColor grayColor] colorWithAlphaComponent:.5f];  
    [self.view addSubview:dimBackgroundView];
    [self.view addSubview:changeProfileImage.view];

you can set a tag for "dimbackground" .. and remove it like this:

dimBackgroundView.tag = 111;//you will do this line when you create the view.
UIView *view = [controllerA.view viewWithTag:111];
[view removeFromSuperview];

To Refresh your viewController :

when the user click the submit button and you remove the B view .. post a notification using NSNotificationCenter like this :

[[NSNotificationCenter defaultCenter] postNotificationName:@"UserSubmit" object:nil];

and in controllerA .. viewDidLoad For example add it as observer like this

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(refreshView) name:@"UserSubmit" object:nil];

and you will implement this function :

- (void) refreshView
{
    //Do your stuff
}
