SomeInnerView

SomeInnerView是一个UIView，可以让您使用另一个图像的一部分选择图像的一部分。例如，这可以是同一张图片。例如，我只是在背景图像上方添加了一个模糊效果视图，当选择的部分是一个没有效果的图像时。选择的结果保存在属性x、y、right、bottom中。它们表示坐标矩形（范围从0到1）

		innerView = InnerView()
		innerView.backgroundColor = .black
		innerView.translatesAutoresizingMaskIntoConstraints = false
		self.view.addSubview(innerView)
		innerView.leadingAnchor.constraint (equalTo: self.view.leadingAnchor).isActive  = true
		innerView.trailingAnchor.constraint(equalTo: self.view.trailingAnchor).isActive = true
		innerView.topAnchor.constraint(equalTo: self.view.topAnchor).isActive           = true
		innerView.bottomAnchor.constraint(equalTo: self.view.bottomAnchor).isActive     = true
		
		guard let sourceImage = UIImage(named: "image") else { return }
	

		innerView.mainImage = sourceImage
		innerView.background.backgroundColor = .red
		
		let blurEffect = UIBlurEffect(style: UIBlurEffect.Style.dark)
		let blurEffectView = UIVisualEffectView(effect: blurEffect)
		
		blurEffectView.translatesAutoresizingMaskIntoConstraints = false
		innerView.background.addSubview(blurEffectView)
		
		blurEffectView.leadingAnchor.constraint(equalTo: innerView.background.leadingAnchor).isActive = true
		blurEffectView.trailingAnchor.constraint(equalTo: innerView.background.trailingAnchor).isActive = true
		blurEffectView.topAnchor.constraint(equalTo: innerView.background.topAnchor).isActive = true
		blurEffectView.bottomAnchor.constraint(equalTo: innerView.background.bottomAnchor).isActive = true
		
		
		innerView.selectionView.backgroundColor = .white
		innerView.secondaryImage = sourceImage
	
		innerView.x = 0.25
		innerView.y = 0.25
		innerView.bottom = 0.7
		innerView.right  = 0.7
		innerView.isSelectionInitialized = true
		
		innerView.selectionView.layer.cornerRadius = 45
		innerView.selectionView.layer.masksToBounds = true

要显示选择视图，您需要设置一个可见矩形并调用

  innerView.isSelectionInitialized = true

将此设置为false将隐藏选择视图

您可以通过设置属性x、y、bottom、right来移动选择。为了允许用户与选择视图交互：

  innerView.selectionView.isUserInteractionEnabled = true

为了将选择视图固定在图像的一部分上

innerView.isSelectionFixed = true
