I have a iPhone application that I am currently converting to a Universal Binary to work with the iPad.

But, I have one strange problem, and ...

I was trying to implement shadow mapping on iPhone, and I allocated two 512*1024*32bit textures for the shadow map and the diffuse map respectively. The problem is that my application started to freeze and reboot the device after I added the shadow map allocation part to the co...

I have a VC controlling a screen of content that has 2 modes; a normal mode and an edit mode.
Can I create a single VC with 2 views, each from separate nibs?
In many situations on the iphone, you have a VC which controls an associated view. Then on
a button press or other event, a new VC is loaded and its view becomes the top level vie...

I'm a newb iPhone developer writing an app that has several large JPGs and sound files. Everything works ok if I drag these non-code resources into my project. But I am wondering if this is the right way to package my app.
In Windows development, I would create a "resource DLL" that keeps the .exe size small. What is the equivalent for...

Hi Everybody, I really like Hudson CI and I do think it is the most useful and effective piece of software ever made for the Agile Application Lifecycle :-)
Anyway if the CI become unstable, the development is going to be really compromised, so keeping an eye on it is CRUCIAL !
Does anybody know about an effective solution for always m...
I have converted a very simple iPhone app to Universal app. Now I need to customize the view on the iPad to use a higher resolution image for the background, move and resize some labels, etc.
How can I do it without changing the iPhone version? I can see that there is a new MainWindow-iPad.xib, but when I open in IB, it looks empty.
Th...
This is a follow on from my previous problems here. Resetting the simulator solved all my troubles before, and I've gone on to complete my App.
I now have the exact same problem when installing the app onto my iPhone device. It picks up an old version of my database, which doesn't have the second entity in it, and crashes when I try to ...
I'm integrating the latest version of the admob sdk (version 20100412) into my app.
The ads get displayed, but I need the app to make some changes when an ad is clicked and admob displays a full-screen browser. However, none of the callback methods (willPresentFullScreenModal, didPresentFullScreenModal, willDismissFullScreenModal, and d...

I have an array (actually in a plist) of dictionaries. Each dictionary has 3 keys in it: (title), (points), and (description).
I am trying to make a NEW array with the values of the key "title" from each dictionary in that first array.

It's really a pain, but always when I draw an UIImage in -drawRect:, it's upside-down.
When I flip the coordinates, the image draws correctly, but at the cost of all other CG functions drawing "wrong" (flipped).
What's your strategy when you have to draw images and other things? Is there any rule of thumb how to not get stuck in this p...
Hi,
I have my 'shake' working fine (using motionEnded), based off of Apple's GLPaint code. When the user shakes the device (running 3.0 and up) I want to open a view controller modally using presentModalViewController.
In my appdelegate I have the notification (as per the GLPaint sample code):
[[NSNotificationCenter defaultCenter] ad...
