Subclassing a UIAlertView - objective-c

I'm desperately trying to find a way to make a custom UIAlertView that allows to display long texts and that would also allow to scroll the text as well. It seems to be possible since I've seen a few apps that do it (biteSms for instance) but I don't know how to do it.
Could someone help me please and tell me if any of you has managed to do it ?
Thanks for your help.

Page indicator in Carousel for Xamarin.Forms, it is possible?

I would like to show some page indicator in the Xamarin.Forms carousel, with dots or something similar.
The purpose is to let to the user know that there are more pages if he does swipe. The UX would improve a lot.
Any possibility/way to do this?
I wanted to implement the exact same thing and came across the following link:
http://chrisriesgo.com/xamarin-forms-carousel-view-recipe/
I found it quite easy to implement and figure out what is going on after reading through the post. A great option and well worked example in my opinion!
You'll only need to follow the example related to "Dots" of course :)
Hope this helps!

Which NSView does Finder use to show files?

I want to show all the files in a folder as shown below(image):
Also, I would be really thank full if you could give me link of some tutorials to study the very view and how to use it.
Many Thanks in advance.
This is an NSBrowser. Read Apple's Browser Programming Topics for even more info. I think their browser may be customized to get the full behavior seen in the Finder.

Posting contents of UILabel to Facebook?

Just dabbling with some iOS stuff and would like to integrate Facebook (and eventually twitter).
I have a UILabel which randomly changes and would like to post the contents of it to Facebook. Can anyone help on how to achieve this? Perhaps point me in the direction of resources? As a newbie I'm finding it difficult to find what I need.
Thanks in advance.

how to make a 9*9 grid view in Objective C under Xcode 4.3?

i have searched Xcode controls but doesn't found anything that makes a GridView like the one in the lecture below so, how to make a one like that? thanks
As #Stephen pointed out, there's AQGridView, but here are a few others I've looked at, each offering some different functionality based on what you're looking for: GMGridView, NRGridView, MMGridView
There is no such component built in to iOS. So you'll either need to write your own or look for an open source version. I'm aware of AQGridView; I'm sure there are others.
iOS 6 has a UICollectionView that might work

How to create transparent notification window?

I'm not sure of the correct name, but I am wondering how to create (in Objective-C) a transparent notification "window/panel", such as is shown when you change the volume intensity, or keyboard illumination, or display brightness. I want to put my own icon/text on it, for my own notification.
I don't know the words to Google for, so I'm asking here.
Thanks for any suggestions.
Matt Gemmell's RoundedFloatingPanel component on his sample code page may do just what you're looking for.
After looking into using the solutions provided by the other two given answers, I found that they would not work for my purposes. So, I wrote up my own library:
BHBezelNotification
Growl is a widely-used implementation of this. By default, it doesn't look exactly like the system overlays, though it is skinnable - you probably want the Bezel notification:
See the Growl Developer Documentation for more.
