Need hooks for delete confirmation
It would be nice if there was a way to prompt the user for delete confirmation before an image is deleted. I was thinking we could add a separate delegate method called shouldRemoveGalleryItem
so we could make sure that the user wants to delete. I've created a PR here.
Another option is to make GalleryImageViewController.deleteItem
a public method so we can supply our own delete button in the header or footer and call the deleteItem
method ourselves. I didn't create a PR for this option but let me know what you think.
