Comment supprimer l'effet de flou sur l'image lorsque l'utilisateur touche l'image

Dans mon application, il existe deux options de flou et de flou d'image en touchant l'image. Je fais cela pour brouiller l'image lorsque l'utilisateur touche l'image

override func touchesMoved(_ touches: Set<UITouch>, with event: UIEvent?) {
 var croppedImg: UIImage? = nil
 let touch = touches.first
 var currentPoint = touch!.location(in: imgBackground)
 let ratioW: Double = Double(imgBackground.image!.size.width / imgBackground.frame.size.width)
 let ratioH: Double = Double(imgBackground.image!.size.height / imgBackground.frame.size.height)
 currentPoint.x *= CGFloat(ratioW)
 currentPoint.y *= CGFloat(ratioH)
 
 let circleSizeW = 25 * ratioW
 let circleSizeH = 25 * ratioH
 
 
 currentPoint.x = CGFloat((Double(currentPoint.x ) - circleSizeW / 2 < 0)? 0: Double(currentPoint.x ) - circleSizeW / 2)
 currentPoint.y = CGFloat((Double(currentPoint.y ) - circleSizeH / 2 < 0)? 0: Double(currentPoint.y ) - circleSizeH / 2)
 
 
 let cropRect = CGRect(x: currentPoint.x, y: currentPoint.y, width: CGFloat(circleSizeW), height: CGFloat(circleSizeH))
 
 
 croppedImg = croppIngimage(byImageName: imgBackground?.image, to: cropRect)
 
 // Blur Effect
 croppedImg = croppedImg?.imageWithGaussianBlur9()
 
 
 croppedImg = roundedRectImage(from: croppedImg, withRadious: 4)
 imgBackground.image = addImage(to: imgBackground.image, withImage2: croppedImg, andRect: cropRect)
}
func imageWithGaussianBlur9() -> UIImage? {
 // Blur horizontally
 UIGraphicsBeginImageContextWithOptions(size, _: false, _: scale)
 draw(in: CGRect(x: 0, y: 0, width: size.width, height: size.height), blendMode:.normal, alpha: 0.5)
 for x in 1..<5 {
 draw(in: CGRect(x: CGFloat(x), y: 0, width: size.width, height: size.height), blendMode:.normal, alpha: 0.5)
 draw(in: CGRect(x: CGFloat(-x), y: 0, width: size.width, height: size.height), blendMode:.normal, alpha: 0.5)
 }
 let horizBlurredImage = UIGraphicsGetImageFromCurrentImageContext()
 UIGraphicsEndImageContext()
 // Blur vertically
 UIGraphicsBeginImageContextWithOptions(size, _: false, _: scale)
 horizBlurredImage?.draw(in: CGRect(x: 0, y: 0, width: size.width, height: size.height), blendMode:.normal, alpha: 0.5)
 for y in 1..<5 {
 horizBlurredImage?.draw(in: CGRect(x: 0, y: CGFloat(y), width: size.width, height: size.height), blendMode:.normal, alpha: 0.5)
 horizBlurredImage?.draw(in: CGRect(x: 0, y: CGFloat(-y), width: size.width, height: size.height), blendMode:.normal, alpha: 0.5)
 }
 let blurredImage = UIGraphicsGetImageFromCurrentImageContext()
 UIGraphicsEndImageContext()
 //
 return blurredImage
}

Le code ci-dessus fonctionne parfaitement lorsque nous floutons l'image

Que dois-je faire lorsque l'utilisateur souhaite supprimer l'effet de flou

Solution du problème

vous devez placer 2 UIImageView l'un sur l'autre. En bas, vous devez placer l'image originale.

@IBOutlet weak var imgBackground:UIImageView!
@IBOutlet weak var bottomViewImage:UIImageView! // original image

Add below code for unblur the image -:

 var croppedImg: UIImage? = nil
 let touch = touches.first
 var currentPoint = touch!.location(in: imgBackground)
 let ratioW: Double = Double(imgBackground.image!.size.width / imgBackground.frame.size.width)
 let ratioH: Double = Double(imgBackground.image!.size.height / imgBackground.frame.size.height)
 currentPoint.x *= CGFloat(ratioW)
 currentPoint.y *= CGFloat(ratioH)
 
 let circleSizeW = 25 * ratioW
 let circleSizeH = 25 * ratioH
 
 
 currentPoint.x = CGFloat((Double(currentPoint.x ) - circleSizeW / 2 < 0)? 0: Double(currentPoint.x ) - circleSizeW / 2)
 currentPoint.y = CGFloat((Double(currentPoint.y ) - circleSizeH / 2 < 0)? 0: Double(currentPoint.y ) - circleSizeH / 2)
 
 
 let cropRect = CGRect(x: currentPoint.x, y: currentPoint.y, width: CGFloat(circleSizeW), height: CGFloat(circleSizeH))
croppedImg = croppIngimage(byImageName: bottomViewImage?.image, to: cropRect)
 croppedImg = roundedRectImage(from: croppedImg, withRadious: 4)
 imgBackground.image = addImage(to: imgBackground.image, withImage2: croppedImg, andRect: cropRect)
