Sorry to get to this pull request nearly three years later! You may or may not even still care about this, but I wanted to give this a review anyway.
I appreciate this change, but before it makes it in, I'd like to see a couple things changed on it: see the changes I've requested at line-items below.
Additionally, I feel like a better model for adding a feature like this would be for the index view to ask its delegate for a configurable view (one that conforms to a protocol), and then for the index view to display that view anchored to the touch point in a particular way (maybe configurable with an enum: top/middle/bottom). I don't expect you to make any of those changes to this pull request because it's asking quite a bit! But one thing I plan on doing in the near future is rewriting this in Swift because it's woefully out of date, and I would like to add functionality for a peek view like you've done here. If you're still interested in making the changes below, that's fine, but know that they may be rewritten soon with something a bit more customizable.

The name for this delegate function doesn't tell me anything about what it does. The other two indicate actions a user takes against the index view. What does this one communicate? Can you rename it to something more descriptive, please?

Can you remove this file from your changes?

Apple has advocated against using -viewWithTag: due to its inability to handle tag index collisions, especially when using third-party code, and this could potentially introduce collisions with other third-party code when added to somebody else's project.
Can you update this to use something other than viewWithTag? A retained reference perhaps?

No change needed here, but I just want to call this out: I would prefer the offset behavior and size of this peek view be a bit more customizable, but I think this is good for now. I may update this code to add customization options in the future.
