UIImagePickerControllerDelegate not being called, selected image never displayed

Question

I'm stumped. Everything is working except it's not. I can call up the camera interface and take or select a photo yet UIImagePickerControllerDelegate is never being called (I've put two print statements that well, never get printed). Everything is correctly connected in IB, or so I believe it is (I'm fully ready for it so be something totally minor that I missed). Anyone care to take a frtesh set of eyes and go over this to see if I just can't see the forest for the trees?

Thanks in advance.

Answer 1

You have to specify that the UIImagePickerController's delegate is self, so that the events are triggered.

In your case:

afterImagePicker.delegate = self

Answer 2

@raja Kishan caught my stupid simple error of forgetting to set the delegate.

Now, where's the facepalm emoji.
