Hi,
First of all, thank you for the great chapter!
My question is, how can I save the main image data into a UIImage and then pass the image data to the next view controller through prepare(for segue:) so that I can do something more than just saving in the Photo Library with it?
I attempted to do this by doing the following:
Step 1) Added these in the PhotoCaptureDelegate.swift file:
- ‘var photoTaken: UIImage?’ and
- ‘let photoTaken = UIImage(data: photoData)’ in func capture( … didFinishCaptureForResolvedSettings: ) {…},
Step 2) And then, added these in the the CameraViewController.swift file:
- ‘var lastUniqueID: Int64?’
- ‘self.lastUniqueID = uniqueID’ in func capturePhoto() {…} and
- ’ if let photo = self.photoCaptureDelegates[lastUniqueID!]?.photoTaken as UIImage? {
self.photoCaptured = photo
} else {
return
}
’ in func prepare(for segue: ).
Unfortunately, this attempt wasn’t successful because the performSegue function was called BEFORE the capture( … didFinishCaptureForResolvedSettings: ) function was called, so the photoTaken variable ended up being always nil.
Thanks for your help in advance. Please let me know if you need any clarification!
