Using The UIImagePickerController to select and upload a photo to server.

Question

I am using the Picker controller with UIImagePickerControllerSourceTypePhotoLibrary .

In the delegate didFinishPickingImage is called, but when I click on the cancel button it doesn't enter:

(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker 

This happens even though the controller is dismissed.

Answer 1

Make sure the class you think it is calling implements the proper delegate protocol.

This case should be UIImagePickerControllerDelegate, like this:

@interface YourClassViewController : UIViewController < UIImagePickerControllerDelegate>

Answer 2

You need to implement the rest of UIImagePickerControllerDelegate. When the cancel button is clicked, the picker will call -imagePickerControllerDidCancel: on its delegate.
