I just had this question too: how to animate a custom editing mode? I didn't really like the solution here, so I decided to think a little bit and found a different solution. I don't know if it's better, but I prefer that one. So I decided to share it here:

In the custom cell (inherit from UITableViewCell), just overload the setEditing:

- (void)setEditing:(BOOL)editing animated:(BOOL)animated {
    [super setEditing:editing animated:animated];

    if (animated) {
        [UIView beginAnimations:@"setEditingAnimation" context:nil];
        [UIView setAnimationDuration:0.3];
    }

    if (editing) {
        /* do your offset and resize here */
    } else {
        /* return to the original here*/
    }

    if (animated)
        [UIView commitAnimations];
}

I don't check if the editing value is the same, but that's just an idea how I did it.
