iOS Swift 3 Image rotated 90 degrees Left

Question

In my app I have a feature to take a picture from camera and upload it to server. My problem is that when I\'m getting response back from server that image is r

Answer 1

Try this (reset you image orientation) before you upload on server

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])
{
    self.PickerFrom = self.PickerFrom2
    if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage
    {
       self.AttachmentImageView.image = pickedImage
    }
    dismiss(animated: true, completion: nil)

    if let updatedImage = self.AttachmentImageView.image?.updateImageOrientionUpSide() {
      uploadGalleryImage(image: updatedImage)
    } else {
      uploadGalleryImage(image: self.AttachmentImageView.image!)
    }

}

func uploadGalleryImage( image:UIImage)
{
    let imageData: NSData = UIImagePNGRepresentation(image)! as NSData
    let base64String = imageData.base64EncodedString(options: NSData.Base64EncodingOptions(rawValue: 0))
    self.AttachedDocumentURL = "data:image/png;base64,\(base64String)"
}

// Image extension
extension UIImage {

    func updateImageOrientionUpSide() -> UIImage? {
        if self.imageOrientation == .up {
            return self
        }

        UIGraphicsBeginImageContextWithOptions(self.size, false, self.scale)
        self.draw(in: CGRect(x: 0, y: 0, width: self.size.width, height: self.size.height))
        if let normalizedImage:UIImage = UIGraphicsGetImageFromCurrentImageContext() {
            UIGraphicsEndImageContext()
            return normalizedImage
        }
        UIGraphicsEndImageContext()
        return nil
    }
}
