Q:

UIAlertView replacement

It seems that I am always fighting with UIAlertView to make it do what I want.  I'm done fighting - are there any robust UIAlertView replacements with the following features, or will I need to write my own?:

ability to customize the alert-view size/position
ability to change the layout of the
buttons (stacked vs. side-by-side)
ability to prompt users for input via UITextField or UITextView
resizing / repositioning behavior
when the keyboard appears
ability to have a UITextView for
scrolling text
pixel-perfect copy of UIAlertView for
basic display
ideally interface compatible with
UIAlertView - i.e. it is a drop-in-replacement.

I've found a few blog and stackoverflow posts which implement customizations on a UIAlertView - this is NOT what I want.  Nor do I want a guide on how to implement a custom AlertView -- I know how, I just want to find one that is already community maintained.  I want a ground-up replacement that is safe for App Store submission and future-proof against UIAlertView changes (yes, I've been burnt...)
Please respond with comments if you have suggestions for other desirable features.

A:

Answering my own question.
I searched high and low for a prefab UIAlertView project that offered the features I was looking for.  I'm sure they exist -- I've seen apps with great alerts.  Their authors must not be sharing - which is totally fine, I understand.
So I wrote my own.  TSAlertView is a ground-up implementation of a modal alert view that is interface-compatible with UIAlertView.  In terms of visual look, while it is not a pixel-perfect copy, it comes very close.  The features it offers are basically what I outlined in the original question:

ability to set the display-width and max-height of the alert view.  This allows me to have nicer looking alerts on iPad.
ability to specify the layout of the buttons (stacked vs. side-by-side), even if there are only two buttons.  This always bothered me with UIAlertView -- if I had two buttons they were always placed side-by-side.  A big problem if the button text didn't fit.
ability to prompt users for input via a UITextField.  Once in a while you just need a quick and dirty way to prompt the user to enter something.
resizing / repositioning behavior when the keyboard appears.  (happens when prompting for user-input) 
ability to have a UITextView for scrolling text.  Can explicitly set this option instead of relying on UIAlertView to swap in a UITextView for long text.
near pixel-perfect copy of UIAlertView for basic display.
support for custom backgrounds
is interface compatible with UIAlertView - i.e. it is a drop-in-replacement.

I've used a handful of great open-source projects in my code in the last year.  My two favorites are MBProgressHUD and MGSplitViewController, each hosted at github.  I decided to share TSAlertView in the same manner.

The initial implementation surely has some bugs.  I haven't used it in a shipping project yet, but I am using it in my current project to be completed in a few weeks.  If you want to try using it yourself, please feel free.  Post any issues on github, or better yet, submit a fix.
Enjoy!
Here are some screenshots showing 1) 2 stacked buttons 2) input capability  3) explicit width setting
