Remove Blur View from another subview

I have added 2 subviews into my view(EOPSessionsViewController), blurEffectView and reLogInView. 

    if (!UIAccessibilityIsReduceTransparencyEnabled()) {
        self.view.backgroundColor = [UIColor clearColor];

        UIBlurEffect *blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleExtraLight];
        UIVisualEffectView *blurEffectView = [[UIVisualEffectView alloc]initWithEffect:blurEffect];
        blurEffectView.tag = 123;
        blurEffectView.frame = self.view.bounds;
        blurEffectView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

        [self.view addSubview:blurEffectView];
    }else{
        self.view.backgroundColor = [UIColor blackColor];
    }

    self.reLogInView = [[ReLoginViewController alloc]initWithNibName:@"ReLoginViewController" bundle:nil];

    [self.view addSubview:self.reLogInView.view];
    self.reLogInView.view.frame = CGRectMake(0, 0, self.view.frame.size.width/2, self.view.frame.size.height/2);
    self.reLogInView.view.center = self.view.center;
    self.reLogInView.view.backgroundColor = [UIColor grayColor];
    self.reLogInView.view.layer.borderColor = [UIColor blackColor].CGColor;
    self.reLogInView.view.layer.borderWidth = 3.0f;

I want to remove blurEffectView and reLogInView when user clicks a cancel button inside reLogInView. As of now, i can remove reLogInView with the code below. 

- (IBAction)cancel:(id)sender {

    [self.view removeFromSuperview];

}

My question is how to remove blurEffectView at the same time? Note that 3 of them are different classes.

Try adding something like this:

self.reLogInView.sessionsVC = self;

in the first code snippet. (declare it like this):

@interface ReLoginViewController : (???) <???>
...
@property (strong) EOPSessionsViewController *sessionsVC;

then:

- (IBAction)cancel:(id)sender {
    [self.view removeFromSuperview];
    [self.sessionsVC.blurEffectView removeFromSuperview];
}
