UITableView didSelectRowAtIndexPath: not being called on first tap

I'm having an issue with UITableView's didSelectRowAtIndexPath. My table is setup so that when I select row it initializes a new view controller and pushes it.

UIWindows or UIViews

I need three different sections in my app: a login screen, a main screen, and one that takes place in landscape mode, all totally different.

I don't have experienc...

ABPeoplePickerNavigationController alternative that allows selection of multiple people

I'd like to prompt the user to select 1 or more people from their address book, but ABPeoplePickerNavigationController doesn't allow that (which is ironic, since it's people picker, not a person picker). Before I go create my own, does anyone know of an alternative (open source) implementation of such a controller? ...

Is there any way to modify a UITableView's separator cell?

My app will be using slightly thicker separator lines in tableViews - about 3x the thickness.

UITextView does not respect the secureTextEntry property

I'm trying to get a UITextView (NOT a UITextField) to act as a password field where the text is obfuscated as you type into it.
