Question

The "textboxes" that appear when clicking Tweet or Share for Twitter and Facebook. What are those made of? Can something similar be made? I am trying to customize them so that it will function as "comment" for a tableView. I’m talking of these two:

I am trying to make it say "Comment" instead of "Tweet" and "Facebook".. And then "Done" where it says "Send" and "Post". Any idea how/where I can create/customize these?

Answer 1

These are private view controllers. You can’t (well, shouldn’t) customize them—you’ll have to reimplement them yourself.

You can however, use the private method -recursiveDescription to get an idea of how the view hierarchy’s constructed. Create a simple app that shares some text using UIActivityViewController. Present it, pick Twitter or Facebook, then pause the app in the debugger. Type po [[[UIApplication sharedApplication] keyWindow] recursiveDescription] into the console to list the current view hierarchy.

EDIT: Ok, I was curious…

Basically, it’s what you’d expect: a bunch of background images, a label and buttons to fake the navigation bar style and a big text view for content.
