iOS Jump to next cell in UITableView when cell scrolled

I would like to implement a UITableView with cells that are full screen. When the user moves the cell up a portion, I would like to jump to the next cell as opposed to allowing it to scroll naturally.

I can't see a great deal of questions or answers out there on this, and perhaps it's because it's a daft idea, but the client wants to see it and the designer has designed it as such so I really must try.

Does anyone have ANY suggestions on how to implement this?

Thanks. (and thanks for pointing out my ignorance in not saying thanks!)

Solution

If your cells are going to be the same size as your tableView's height, set the pagingEnabled property to YES. This will make it snap to a full cell on each vertical swipe. I would ensure that the height is exactly full-screen if you do this, otherwise you'll end up with some weird offsets as you scroll.

- (void)viewDidLoad
{
    [super viewDidLoad];
    // or somewhere similar
    self.tableView.pagingEnabled = YES;
}

...

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return self.tableView.frame.size.height;
}

It actually isn't a terrible idea- you could achieve similar functionality with a paging scroll-view, but this has the advantage of not needing to have all of your data loaded at once.

Edit: I also had to make sure to disable automaticallyAdjustsScrollViewInsets on the controller, otherwise I had an undesired initial offset for the first cell, just in case you run in to that as well.
