I have a UIView - which I am using as a makeshift toolbar. It contains several UIButtons. (Six, I think) in a horizontal row. The fifth button over will only respond to [TouchUpInside] events when I click the left half of it - whereas all the other buttons work correctly. I have gone crazy making sure there weren't any other views over...

I have a couple of iOS applications which present inherently linearly organised information, allowing the user to move forward and backward through the data with on-screen controls. I would like to allow users with the keyboard dock or a paired bluetooth keyboard to use the arrow keys to move back and forth as well. Since the apps are ...
I'm working on a drawing app. I want the user to be able to "drop" a shape on the screen and then move, resize or rotate it as desired. The problem is with the rotation. I have the moving and resizing working fine. I did this before with a rather complex and memory/processor-intensive process, which I am now trying to improve. I've ...

How do I create a resource bundle to use in an iPhone/iPad app? Is it simply a folder with the .bundle extension or do I have to do something else to make it work? Are there any special considerations for Universal apps (ie: do I have to create separate bundles for each platform?) and localized resources? I would like to create and use...

I'm developing an iPhone/iPad app that supports dragging items between table views. Since all the tables don't fit on screen, I've written a custom UIScrollView that lays them out horizontally, and supports paging. While I've gotten the primary drag and drop together, there are a few remaining issues I can't get past. After the user h...
Hello, I’ve been looking into the Accelerate framework that was made available in iOS 4. Specifically, I made some attempts to use the Cblas routines in my linear algebra library in C. Now I can’t get the use of these functions to give me any performance gain over very basic routines. Specifically, the case of 4x4 matrix multiplication....

I have no experience with audio programming at all and have been looking at the AV Foundation Framework thinking this is what I need to use to create an app that allows me to record and do simple editing of a recording. By simple, I mean have the ability to go to a part of my recording and snip out a segment. I've gathered that I shoul...
According to the iOS Reference Library: In iOS 4.0 and later, it is possible to mark individual resource files as usable only on a specific type of device. Does this mean that if you're creating an Universal app for 3.X devices, and the 3.2 iPad in particular, you can't use device-specific resources with the ~ipad and ~iphone...
