设置stackView时发生内存泄漏-Swift-以编程方式

如何解决设置stackView时发生内存泄漏-Swift-以编程方式

我正在设置一个底部按钮StackView，但我发现，只要设置它，我就会发现内存使用立即增加。

这是我在viewDidLoad（）中实现的用于设置底部stackView的代码：

 @objc fileprivate func setUPUI(){
    
    let buttonsstackview = UIStackView(arrangedSubviews: [acceptButton,detailButton,cancelButton])
    
    
    buttonsstackview.axis = .horizontal
    buttonsstackview.distribution = .equalSpacing
    buttonsstackview.alignment = .center
    
    buttonsstackview.spacing = 20
    
    //defining buttons Constraints
    acceptButton.heightAnchor.constraint(equalToConstant: sideViewsSize).isActive = true
    acceptButton.widthAnchor.constraint(equalToConstant: sideViewsSize).isActive = true
    
    detailButton.heightAnchor.constraint(equalToConstant: centerViewSize).isActive = true
    detailButton.widthAnchor.constraint(equalToConstant: centerViewSize).isActive = true
    
    cancelButton.heightAnchor.constraint(equalToConstant: sideViewsSize).isActive = true
    cancelButton.widthAnchor.constraint(equalToConstant: sideViewsSize).isActive = true
    
    
    
    //setting shadows
    acceptButton.setupShadow(opacity: 0.7,radius: 4,offset: .init(width: 0,height: 0),color: .darkGray)
    detailButton.setupShadow(opacity: 0.7,color: .darkGray)
    cancelButton.setupShadow(opacity: 0.7,color: .darkGray)
    
    
    buttonsstackview.translatesAutoresizingMaskIntoConstraints = false
    
    
    self.view.addSubview(buttonsstackview)
    
    buttonsstackview.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor,constant: -5).isActive = true
    buttonsstackview.heightAnchor.constraint(equalToConstant: 90).isActive = true
    buttonsstackview.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
    buttonsstackview.leadingAnchor.constraint(greaterThanorEqualTo: view.leadingAnchor,constant: 20).isActive = true
    buttonsstackview.trailingAnchor.constraint(lessthanorEqualTo: view.trailingAnchor,constant: -20).isActive = true
   }
