So I'm going through the first tutorial in O'Reilly's iPhone 3D Programming book. At this point in the tutorial, it pulls all the OpenGL ES stuff into a seperate c++ interface. I have followed the book to the letter, as far as I can tell, yet I can't seem to figure out this compiler error. I'm fairly new to C++ (mostly C# in the past), s...
Does anyone know what this error means? * attempt to pop an unknown autorelease pool I am seeing this in my app that uses NSOperations in NSOperationQueue. Each operation has it's own Autorelease pool. Since each operation is parsing xml and pushing information into Core Data, I periodically 'drain' my autorelease pool and re-create i...

Hi, I installed the iOS 4 SDK yesterday. I previously had the 3.1.2, 3.1.3 and 3.2 SDKs installed. Since installing the iOS 4 SDK, I only have 3.2 and 4.0 available in Xcode. When I load an Xcode project that was targeting an older version (say 3.1.2), it says "Base SDK Missing" in the toolbar. I've been able to reset the project to ta...
Hi, I have googled a lot and read a lot about the leaks issue with NSURLConnection, but none of them gives a definite answer as to what is the solution to overcome these leaks. I create an asynchronous connection and every time the connection is established, I get a GeneralBlock-3584 leak. Sometimes the responsible library is shown to b...

I have numerous buttons that go to different views on my main page and they all work the same way - they go the view and the area for the back button has the text of the title of the main page. Then on one view, it says "Back". When you click "Back" - the view stays the same but the back button text changes to the same as the rest with...
I made a bunch of little individual pictures, each with a separate CALayer, and they're supposed to fade in and out asynchronously at different rates. Each has a background sublayer and a fill sublayer. A timer runs in the background to animate each one individually at specific moments. For the current behavior of the program, rather ...

The problem I'm having is the old time doesn't get erased when the new time gets printed.

I'm using a series of shaders to perform realtime image processing on the iPhone (3GS/4/iPad). The fps isn't what I'd like it to be. Are there any tools that I can use to help me work out what the bottlenecks are? ...

I have a Table View that fetches data from Core Data using FetchedResultsController and it registers for the data update. On a second thread, I download the data from the server and update the same data (that's used by the Table View). The update is not complicated: it is just updating a BOOL field of the entity. When I call the save o...
Hi I'm new to working with timers on the iPhone and would need some support. I have a method as below that takes the time and update a label in my user interface. I also have an NSTimer that calls that method once a second (I only show hours and minutes). This works just fine, except for the first second the App is live (as I understa...
I'm doing iPhone programming after 10+ years as a Java developer. In the Java world, I'm accustomed to using 3rd party libraries for just about everything, from entire frameworks like Spring to small things like the apache commons utilities. Are there similar things available for iPhone development? Where do I find them? I attended th...
