I'm having a very strange problem with the UINavigationController. I found a very similar question here: http://stackoverflow.com/questions/1542040/uinavigationcontroller-not-popping-uinavigationbar-items but the solution there had to do with the fact that the guy had added a category to NSMutableArray, and I'm not doing anything like t...

We've got a scenario where we need to interact with some hardware from a web page -- think ActiveX. In this instance we want to read/write to a specific model of bar code reader.

I'm trying to figure out how I could create a curl or peel effect on an image in my iPad app using Core Animation, but as I'm learning the API, I only understand different ways to move, scale, and rotate the 2D image (including the 3D transformations). I'd like to accomplish this effect on small, individual layers (i.e. sprites) that ha...
Hi, I am using the UIWebView on iPad, which I initialize by the code below. The problem is that the view is never displayed on the top of the page just under the Status bar, but there is another 44px space (filled with black color) - for Navigation Bar, which I do not want to display. Any hints how I can make the UIWebView be displayed ...

So, for example, I draw a box ask for the top left corner, rotate the box 270 degrees for example, then how to I query for the position of the "new" top left corner, which in this case is effectively the original...

I have 3 UITableViews on a UIView in which I load 3 different sets of data from NSMutableArrays. If I call [myTableView reloadData] the data kind of reloads - it actually gets added to the table along with what ever is already there. So 3 calls to reloadData results in triple listed information. How do I prevent this from happening or...
There's an action in my program which users need to perform very frequently (potentially hundreds of times per session), and I'd like to add a keyboard shortcut for users with a bluetooth keyboard.

In some of the applications, I have seen that we have an option to increase or decrease the fontSize of the text inside the label.

And in some cases like news applicatio...

I have several questions about that: I know a little bit about MIDI, but I've recently heard about OSC. Obviously MIDI is supported by almost all DJ software applications, but do...
