CGContext vs CALayer
Category : Operating Systems

I'm trying to get a handle on Quartz 2D and looking at the online book Quartz 2D Graphics for Mac OS X Developers.


One very basic thing that is confusing me is the CGContext. For example, I can draw a simple "U" shape with the code below and use it in a CAShapeLayer without referencing a CGContext. Is the context implied/provided by default by the CA

CATiledLayer to CALayer
Category : Mobile Programming

I have a view with a CATiledLayer backing. I want to take the visible tiles from this CATiledLayer UIView and add it to another view as its CALayer backing, thus recreating the visible image in another UIView that doesnt use CATiledLayer.

bringSubviewToFront for CALayer
Category : Mobile Programming

I'm wondering if there is a way to bring layer on top of others layers of view. Something like bringSubviewToFront does for UIView class. I think it can be done with zPosition property of the CALayer but this means I have to check zPosition for all layers and then set proper value.


Thanks in advance.

Clickable CALayer UIs
Category : Development Tools & Services

I have a coverflow-like image carousel grabbing photos w/iPhoto scripting bridge. I have the view set to accept first responder and have implemented methods for left and right arrows, but cannot figure out, conceptually, how to approach making the layers clickable. I know that accepting mouse-down events is the containing view's job, but I can't put the pieces together in my head.
