Hi there, I keep getting a -> Program received signal: “EXC_BAD_ACCESS”. In the following code but I don't really understand why. If I comment out the "executeFetchRequest" lines it goes away. Shouldn't the [results release]; be all that's required? Thanks in advance, Matt // Implement viewDidLoad to do additional setup after loa...
I just upgraded to Snow Leopard and have noticed that my NSLog() calls (among other things) in the iPhone simulator are taking quite a long time, way longer than they used to. Did Apple update the simulator to better approximate the iPhone's CPU speed? ...
Thanks to the respondents on this question (http://stackoverflow.com/questions/1396949/this-loop-is-very-slow-i-think-because-i-create-a-lot-of-intermediate-strings-h) I was able to speed up my code many orders of magnitude.

I don't have an IPhone and don't really want to pay $130 a month for a cell phone. (I leave mine in the car most of the time, sometimes the entire weekend.) But I covet the technology as a mobile computing platform. (Cruel Fate.) One of the things I like about it the most is the multitouch capability. How does it look from an API st...

I'm writing an iPhone application and I find that there are three controllers in the application that have very similar functionality. They are similar enough that it doesn't make sense to separate them into three separate classes, so I have a "mode" property that clients of the class use to specify how the controller should behave in c...

Hi, In an app I'm working on, I do not allow shouldAutorotateToInterfaceOrientation, for various reasons, but when the device is moved to landscape orientation, a notification of orientation change is sent, and I run a method that re-arranges the controls in the view. I'd like to have a landscape-oriented navigation bar, too, but I can'...
Hi, I have been developing an iPhone app. and had the Base SDK set to "iPhone Device 3.0" and Deployment target set to "iPhone OS 3.0". Everything worked fine.
