Setting conversations on screen - opengl-es-2.0

I want to have NPC conversations be displayed on screen like the example picture below, but I am not sure how to go about doing this. How can I get the text to be displayed on the screen like in the picture below? Any tips or advice pointing in the right direction would be appreciated.

Horizontal scrollable table that is responsive

people,
I am currently trying to create a horizontally scrollable table (filled with pictures) where my content (img with some p) always fitts the screen. This means the height of the content has to adapt depening on your screen resolution or ideally also when browsing from a mobile device... I've tried a lot with HTML and CSS and actually thought this should be an easy task, but I just can't get it to work properly :(
I'd really appreciate some help. How'd you do this?
Thanks in advance!

MKMapview: How to get moving directions of current location pin?

I am working in a maps related application. In my application I would like to display destination pin and current location pin. On top of this I need to display an image like 'arrow' which should display moving direction of the user. Can anyone suggest me how do I achieve this.
Thanks
If I understand you correctly you want something like an arrow pointing which way they are moving, so grab the heading, and draw an overlay image on the map of the arrow. Then have it update the overlay when the heading changes.

Howto create a grid like iTunes

I trying to draw a grid like Apple does in iTunes. A grid of images with an expanding row between the rows when you click one of the items in the grid.
After some googling and searching Stackoverflow all I found was IKImageBrowserView and NSCollectionView. Both options didn't work for me as I could not fit an extra row between the rows of the grid.
As a last resort I'm thinking about using something like NSTableView with NSTableViewGroupCell as a expanding row. But it feels dirty to me. Anyone any experience with this? Need some help to get me in the right direction here.

Clear an IKImageView?

I have an IKImageView set up to display in my mac application but when you don't give it an image, its starts with like a noisy broken screenshot of my own desktop rather than being empty. How can I simply clear it and have it empty?
Thanks.
Only display it IF you actually have an image. If you don't have one just show the user a label or something saying 'No Image' or similar.
