So when I create a reference to an 2d array i have to specify its size? But during runtime I need to decide its size, or change its size? How do I do that?

Instead of NSArray use NSMutableArray.
With that type you can change the size afterwards and add more objects later during runtime.

I set the font size using NSFontSize(10,12,13...80)
But I wonder if there is detail info that describes the font size and related actual size(pixels/points)
I welcome any comment
Take a look at UIFont-Documentation:
http://developer.apple.com/library/ios/#documentation/uikit/reference/UIFont_Class/Reference/Reference.html
There are propertys like
pointSize
lineHeight

In my app I need to get mirrored and rotated copies of video files on iPhone.
What the best and fastest way to do this?
Try this on for size.
The CAReplicatorLayer class creates a specified number of copies of
its sublayers (the source layer), each copy potentially having
geometric, temporal and color transformations applied to it.

Is there a way I could initialize some constant in a method like -(void) viewDidLoad for my screen variables (retina, not retina etc) ?
Thx
In C and Objective-C, constants cannot be assigned at runtime because they are constant. If you are asking how to assign to an instance variable, or make that variable accessible to other classes, please update your question.

Convert your text to curves before you scale it.
