Confirm the approach I should take?
Background: I have a custom scrollview (subclassed) that has uiimageviews on it that are draggable, based on the drags I need to draw some lines dynamically in a subview of the uiscrollview.[Note I need them in a subview as at a later point i need to change the opacity of the view]
So before I spend ages developing the code (i'm a newbie so it will take me a while) I looked into what i need to do and found some possible ways. Just wondering what the right way to do this.
1) create a subclass of UIView and use the drawRect method to draw the line i need (but unsure how to make it dynamically read in the values)
2) on the subview use CALayers and draw on there
3) create a draw line method using CGContext functions
4) something else?
Cheers for the help
