How to add any custom image in Camera screen while capturing image? - ios

Question

I want to add custom UIImage in Camera Screen while user capture the photo. Also i want that image in foreground of that captured image on the same position the image is added.
Here the demo image that explain what i want.
To work around this i have try
let picker = UIImagePickerController()
picker.sourceType = .Camera
picker.view.addSubView(imageView)
But using this code it will only add image not add image with the capture image
Any help is appreciate.

Answer 1

You can use UIImagePickerController's cameraOverlayView property to add the imageView on top of the camera screen:
let picker = UIImagePickerController()
picker.delegate = self
picker.sourceType = .Camera
picker.cameraOverlayView = imageView
presentViewController(picker, animated: true, completion: nil)
For adding the image to the foreground of the captured photo you can create an extension for UIImage:
extension UIImage {
func imageWithOverlayImage(overlayImage: UIImage) -> UIImage {
let imageRect = CGRectMake(0, 0, self.size.width, self.size.height)
UIGraphicsBeginImageContext(self.size)
self.drawInRect(imageRect)
overlayImage.drawInRect(imageRect)
let resultImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return resultImage
}
}
Then you can call it from the delegate method of the image picker:
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
let image = info[UIImagePickerControllerOriginalImage] as! UIImage
finalImage = image.imageWithOverlayImage(overlayImage!)
dismissViewControllerAnimated(true, completion: nil)
}

try putting Overlayview. add custom image to overlayview.
func openCamera(){
let pickercontroller : UIImagePickerController = UIImagePickerController()
pickercontroller.delegate = self
if(UIImagePickerController .isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera)){
pickercontroller.sourceType = UIImagePickerControllerSourceType.Camera
}
else{
}
pickercontroller.editing = false
pickercontroller.showsCameraControls = false
let graphRect:CGRect = CGRectMake(0, 0,pickercontroller.view.frame.size.width-20 ,pickercontroller.view.frame.size.height)
let overlayView : UIView = UIView(frame: graphRect)
overlayView.backgroundColor = UIColor(colorLiteralRed: 0.0/255.0, green: 0/255.0, blue: 0.0/255.0, alpha: 0.5)
overlayView.layer.opaque = false
overlayView.opaque = false
var maskLayer : CAShapeLayer = CAShapeLayer()
overlayView.layer.mask = maskLayer
}
