In the process of localizing my app, I have about 50 resources (mostly xibs) that need to be localized. I know how to add a localization for each file, but it's a pretty time consuming process to open the info panel and add the localization for each file. Is there any way to select multiple files and add a localization to each of them i...
Hi My application contains a table view with rows and sections. When I delete the last item of a section, I delete the section. It works fine.

I was having a problem where my Dev cert didn't expand (was not linked) to my private key. I tracked the issue down to a discrepancy in the email used to create my Dev Cert and the one keychain was auto-selecting when I installed my CSR that I created to make my Dev cert. I verified this by examining the contents of my CSR as follows. ...

Are there any repositories around for open sourced iPhone and iPad components? For instance, I have found myself needing to create several new types of table cells to mimic some of Apple's existing functionality (for instance, all the different types of table cells present in the Settings application).

I'm developing for the iPhone and am looking for a good Cocoa/Objective-C library for working with SQLite. I don't want to use the standard procedural SQLite C API. I see options at sqlite.org under the Objective-C section, but am not sure which is the best in terms of library API design, stability, and functionality. I'd like to use ...
Hi all, When a PNG is added to an XCode iPhone project, the compiler optimizes it using pngcrush. Once on the device, the image's rendering performance is very fast. My problem is that my application downloads its PNGs from an external source at runtime (from Picasa Web albums, using the Google Data APIs). Unfortunately, these images...
Hi, I have been programming with the iPhone SDK for some time now. I have not been using Interface Builder. This scares me a little. I know that in effect I may be 'fighting the framework' but I do not see it that way. I find it very easy to just instantiate my UITabBarController in my app delegate, instantiate a UINavigationControl...

iPhone OS 3.0 is being announced and previewed next week (March 17). We all know the feature set users want. Copy/paste, MMS, Flash on iPhone, etc. We'll see about those.
