You can use UIPopoverBackgroundView to modify the design of your popover view.

What is the name of this dismissable viewcontrollable in iOS?

I just want to know is this a custom view controller or it is something provided by apple, if thats the case what is its name?
Its a custom modal view controller which you can animate in with UIViewControllerTransitionCoordinator. If you don't want to mess with the code then consider using the Hero pod which can acheive a similar effect.

Implementing a "context menu" with a grid of buttons

I'm wondering whether there's a better way of implementing a "context menu" in my app. This is a screenshot of how it currently looks like and as you can see, almost the entire screen is already filled up with entries:
This is actually a UIAlertView with multiple "other" buttons.
I wondered if it's possible to create sort of a grid layout within the alert view and add three buttons per row which show icons only, instead of labels (in order to save some space). I'd like to make it similar to this (photoshopped) layout:
I read that it's possible to create a popup with custom stuff in it by using a UIView but perhaps you guys know an easier trick of accomplishing the same thing with an UIAlertView.
Is this even possible with an alert view?
it's impossible to create an UIAlertView like this.. Create a new UIView and add it to your viewController with [self.view addSubview:..]
You should use UIActionSheet instead of UIAlertView in this case. Or you can use modalViewController something like this: http://timneill.net/2010/09/modal-view-controller-example-part-1/

Displaying 2 columns in UIActionSheet

Is something like this possible? How?
Image made with some simple Photoshop.
It is not possible with the default UIActionSheet, However you can try custom control like
TweetBot like UIAlertView and UIActionSheet replacement for iOS
Create your own view controller with the desired view layout and animate the view when presenting. It's much easier than risking changing the default UIActionSheet look and feel.
