I've seen that it's possible to get the latitude and longitude (geocoding, like in Google Maps API) from a street address, but is it possible to do the reverse and get the street address when you know what the lat/long already is? The application would be an iPhone app (and why the app already knows lat/long), so anything from a web ser...
In several cases I want to add a toolbar to the top of the iPhone keyboard (as in iPhone Safari when you're navigating form elements, for example). Currently I am specifying the toolbar's rectangle with constants but because other elements of the interface are in flux - toolbars and nav bars at the top of the screen - every time we ma...
I've got some code that resizes an image so I can get a scaled chunk of the center of the image - I use this to take a UIImage and return a small, square representation of an image, similar to what's seen in the album view of the Photos app. (I know I could use a UIImageView and adjust the crop mode to achieve the same results, but these...
Not having pored through the NDA for the iPhone, I'm not quite clear on what was prohibited that is now allowed, post-dropping of the NDA. Is there any idea of the type of question previously closed here, for instance, that would now be re-opened or re-asked? And more broadly across the web, what level of discussion and help can we now h...
I am developing an iphone application and have to parse xml files in order to put them into a database. I will also be using those same xml parsers in my app so users can import their own data. I was wondering how I can extract those xml parsers into a bundle or a library so I can use them both in my iPhone app and in a command line ap...
I simply could not make it work, and I am wondering if I am wasting my time, or if I am simply stupid! Sorry I don't have the exact error I have right now. But I just want to know if it work or not! ...

In an app I'm working on, I have a plain style UITableView that can contain a section containing zero rows. I want to be able to scroll to this section using scrollToRowAtIndexPath:atScrollPosition:animated: but I get an error when I try to scroll to this section due to the lack of child rows. Apple's calendar application is able to do ...
I'm developing an iphone app that uses the built in sqlite db. I can view the db when running the simulator but how do i access the db instance on the physical device?? Any help is greatly appreciated. FYI: i'm trying to view the open the db via the sqlite3 command line so I can execute arbitray sql against it. For the simulator, I can...
I'm working on a game where I need to let the player look at a plane (e.g., a wall) through a lens (e.g., a magnifying glass). The game is to run on the iPhone, so my choices are Core Animation or OpenGL ES. My first idea (that I have not yet tried) is to do this using Core Animation. Create the wall and objects on it using CALayers....
Can the iPhone SDK take advantage of the iPhone's proximity sensors? If so, why hasn't anyone taken advantage of them? I could picture a few decent uses. For example, in a racing game, you could put your finger on the proximity sensor to go instead of taking up screen real-estate with your thumb. Of course though, if this was your only ...
I'm used to coding Java Swing UIs, and in those if you have some properties that change, and you want your UI to update, you would implement the observer/observable pattern. In Java you do this normally by having your class maintain a list of listeners that it notifies of different events. I've played with Objective-C on the Mac, and th...
I have noticed that some apps like Safari and Mail show a loading indicator in the status bar (the bar at the very top of the phone) when they are accessing the network. Is there a way to do the same thing in SDK apps, or is this an Apple only thing? ...
If I spawn a new thread, and then within it I push a new controller onto my UINavigationController, using code like this... (a) not working -(void)myCallbackInThread { // move on... UIApplication* app = [UIApplication sharedApplication]; [app changeView]; } then I find that the view appears, but does not respond to user i...
This seems like it should be simple but after a couple hours of googling I have not figured it out. I know I can add iCal links using ICS files, but this does not work on the iPhone. BTW, when I say iPhone I would like it to work on the touch also. Anyone have any luck with this? ...
I have a function in which I get en external resource from the web using cocoa's Url object. And it works fine on the simulator, but occasionally fails on the device itself (it's a google query so the resource obviously does exist). Which leads me to believe that there is some internal timeout barrier on the hardware, but haven't read t...
I'm wondering what's a reasonable size for iPhone Apps. Right now I'm working on an iPhone game, and of course it loads fast into my device since I'm connected directly to it through a USB cable, but I've no idea how long it would actually take to download from the App Store. In my case it's about 2mb in size, which is reasonable for a ...
Any pointers on how to initiate serial communication with the iphone? Or any other idea to interact with external hardware? ...
When using one's own iPhone for development it's easy enough to access any crash logs via XCode->Organizer->Crash Logs. How does one access crash logs on another person's phone if they don't have it set up for development in XCode, as would likely be the case if you were distributing your app to them via ad hoc distribution for beta tes...
I'd like to zoom and unzoom in ways the base class doesn't support. For instance, upon receiving a double tap. ...
