Swift Blurの取り外し方について

SwiftのBlurの取り外し方について質問です。

以下のcodeでPopUp Viewが取り外された時と同時に
ButtonでかけたBlur Effectを外したいと考えております。

Swift
1
2import UIKit
3
4class ViewController: UIViewController {
5
6/* PopUp View */
7@IBOutlet var addItemView: UIView!
8
9/* Backgounrd Image */
10@IBOutlet weak var backgoundImg: UIImageView!
11
12/* Blur Effect */
13@IBAction func BlurEffect(_ sender: Any) {
14
15
16    /* setting of addItemView */
17    addItemView.center = self.view.center
18
19
20    /* Setting of Animation */
21    self.backgoundImg.addBlurEffect() /* Blur */
22    addItemView.transform = CGAffineTransform.init(scaleX: 1.3, y: 1.3)
23    addItemView.alpha = 0
24
25    UIView.animate(withDuration: 0.4) {
26        self.view.addSubview(self.addItemView)
27        self.addItemView.alpha = 1
28        self.addItemView.transform = CGAffineTransform.identity
29    }
30
31
32}
33
34/* I want to remove blur effect */
35@IBAction func removeBlurEffect(_ sender: Any) {
36
37    UIView.animate(withDuration: 0.3, animations: {
38        self.addItemView.transform = CGAffineTransform.init(scaleX: 1.3, y: 1.3)
39        self.addItemView.alpha = 0
40
41    }) { (success:Bool) in
42
43        self.addItemView.removeFromSuperview()
44
45    }
46
47}

74    let blurEffect = UIBlurEffect(style: UIBlurEffectStyle.light)
75    let blurEffectView = UIVisualEffectView(effect: blurEffect)
76    blurEffectView.frame = self.bounds
77    blurEffectView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
78    self.addSubview(blurEffectView)
