I want to swap out one view with another by pushing the old view aside to slide in a new view (the kCATransitionPush type). To use CoreAnimation I need to work with CALayers with my views. The problem is that attaching a backing layer to my window content view through setWantsLayer distorts everything in the view. I'm not sure if this h...

I am just trying to make sure I am getting things right as I move forward with Objective-C, two quick questions if I may: (1) Am I accessing the Position object correctly from within Rectangle? am I right to access the Position object contained within by the pointer I set in the init, or is there a better way? (2) In [setPosX: andPosY:...

Alright, so I think I'm doing this the right way. I'm new to objective-C, so I'm not sure about the syntax... I have a set of code that I need to call multiple times, from different files. So I made a new class that has a method in it that I'll call and pass it the values that it needs. Because I am passing different values I've put ...

As a throwaway project for the iPhone to get me up to speed with Objective C and the iPhone libraries, I've been trying to create an app that will play different kinds of random noise. I've been constructing the noise as an array of floats normalized from [-1,1]. Where I'm stuck is in playing that generated data. It seems like this sho...
I am making an app that parses feeds from xml and stores them using Core Data. The issue I am dealing with at the moment is duplicate entries. Every feed I am parsing contains a unique id, something that I get in my model as an int. Now what I need is to tell Core Data not to store that entity if another with the same id already exists. ...

Hi Guys, Ok, the problem is that when my app runs on the simulator it seems to work fine. On the device, however it does not update all the labels.
