# SomeInnerView

![Farmers Market Finder Demo](demo/demo.gif)

SimeInnerView is a UIView allows you to select a part of an image using a part of another image.

As in example this could be the same image.

In example I jus added blur effect view above the background image and when the selection part is an image without any effects.

The resalt of a selection is stored in properties x, y, right, bottom.

They present rectangle of coordinates (from 0 to 1) 

```swift

		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

```

To show the selection view you need to set some visible rectangle and call

```swift

  innerView.isSelectionInitialized = true

```

setting this to false will hide the selection view

You may move the selection by setting properties x, y, bottom, right.

To allow user interaction with selection view:

```swift

  innerView.selectionView.isUserInteractionEnabled = true

```

to fix the selection view on part of an image

```swift

innerView.isSelectionFixed = true

```

# How to use:

```

pod "SomeInnerView"	

```

```swift

import SomeInnerView

```
