I have UIBarButton and user can change image just chose photo or gallery image with image picker. My problem is bad scale image.
If I use AspectFit my UIBarButton look like this:
If I use AspectFill my UIBarButton look like this:
and if I try first change size image and after set it, image all time scratched:
This is my code:
func createPhotoBarButton(image: Data) {
let barbtn = UIBarButtonItem()
var image = UIImage(data:image)
if image == nil {
image = UIImage(named: "photoIcon")
}
let imageView = UIImageView(frame: CGRect(x: 0.0, y: 0.0, width: 35.0, height: 35.0))
imageView.image = image?.resizedImage(newSize: CGSize(width: 35, height: 35))?.withRenderingMode(.alwaysOriginal)
// imageView.image = cropToBounds(image: image!, width: 35, height: 35)
// imageView.image = image
imageView.contentMode = .scaleAspectFill
imageView.layer.cornerRadius = imageView.frame.size.height / 2
imageView.layer.masksToBounds = true
imageView.clipsToBounds = true
self.navigationItem.rightBarButtonItem = barbtn
barbtn.customView = imageView
barbtn.customView?.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(photoTapped(_:))))
}
And here func for resize image:
func resizedImage(newSize: CGSize) -> UIImage? {
guard size != newSize else { return self }
let hasAlpha = false
let scale: CGFloat = 0.0
UIGraphicsBeginImageContextWithOptions(newSize, !hasAlpha, scale)
UIGraphicsBeginImageContextWithOptions(newSize, false, 0.0)
draw(in: CGRect(x: 0, y: 0, width: newSize.width, height: newSize.height))
let newImage: UIImage? = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return newImage
}
Help me plz find the right way to resolving my problem.
