I'd like to work on a SIP project for mobile devices. I've seen links to Siphon, Sipdroid and OpenSIPS. Does OpenSIPS allow for me to make phone calls between two iOS devices in a local network? In other words, I'm trying to do an app for a VOIP company. I'd like to set up my own SIP server and then use theirs later. Is there any reaso...

Right now I'm using this code to get the tiles array of Level sorted: - (NSArray *)sortedTiles { NSMutableArray *sortedTiles = [NSMutableArray arrayWithArray:[self.tiles allObjects]]; NSSortDescriptor *sortDescriptor...
Hi, I am developing an application which is going to be branded to for different clients. For some clients I will release the application myself using my developer account @ apple, but some clients want to release the application using their own developer account. Off course they can create an account for me which I can build the applic...

The reason I choose Plist as my datasource mainly is because it is much easier to manage visually and edit at the later stage. I want to create a simple app that have Picker with 4 components (lets call it component A, B,...

I've been trying to develop a CALayer based "CardView" object that has two layers that face away from each other to present the two sides of a card. I've been working with things like the doublesided property of the CALayer and find the results to be confusing. My base class is CALayer and I'm adding two sublayers to it, one with a M_P...

I figured out how to add one more option to the menu, but if I add two or more options it will say "more" first. clicking it will show all the options I added. But is there a way to show all the options I added upfront? with...
I'm having difficulty extracting amplitude data from linear PCM on the iPhone stored in a audio.caf. My questions are: Linear PCM stores amplitude samples as 16-bit values. Is this correct? How is amplitude stored in packets returned by AudioFileReadPacketData()? When recording mono linear PCM, isn't each sample, (in one frame, in one...
I took the time to set up some Unit Tests and set up the targets in XCode, etc., and they're pretty useful for a few classes. However: I want to test small UI pieces for which I don't want to launch the entire application. There is no concept of pass/fail: I need to "see" the pieces, and I can make dummy instances of all the relevant cl...
After I use Build and Archive to produce an Ad Hoc Distribution build, the Organizer appears. When I select the build, and press Share Application, the dialog pops up, but thereafter none of the buttons work. I can't Distribute For Enterprise, Save To Disk or Email. I press the buttons and they just pop right back up. There are no error...
Anybody can tell me how to make "swipe to mark as read" menu like Reeder (img below)? ...
I've got a detail view with various labels and such providing information about a place (address, phone, etc.). The information provided is taller than an iPhone screen so they're all in a UIScrollView (itself inside a UIView) that allows you to swipe up and down to see everything. I also have an MKMapView inside the scrollview. When it...
I've enclosed a screen dump to make things easier to follow. I've attached my outlets for datasource and delegate and I've created an outlet for my table view, but reloadData doesn't work? Ideally I'd like to only call reloadData after the view has been loaded once? ...
I would like to write an app which can be run on iOS 3.1.3 up to iOS 4.1. I know how to set up the deployment target and the base SDK. After reading the Apple docs it heavily relies on checking if the class is available and/or if an instance responds to a specific selector. Now my questions: What happens if Apple made a class public ...
I read in the iOS Enterprise Developer Program docs that a provisioning profile can be embedded with the application. I am wondering how this is done. Is it simply added to the Payload directory of an IPA, or included in the project directory? I also wonder whether this technique is generally available for all deployment modes/Program...
This is a request for guidance regarding Bluetooth accessory development for iOS devices. Publicly available documentation/discussion seems limited; I assume this is due to the MFI NDA. And I didn't find the quantity/variety of iOS Bluetooth accessories I'd expect if accessory development was as accessible as iOS development in general...
