I'm making an app to allow me to stitch images together into a panoramic scene. I want to be able to turn the Flash LED on the iPhone 4 programatically. How can I do this? I read the documentation and discovered that I need to use AVCaptureFlashMode but I can't figure out how 2 use it? any help would be appreciated. Updated Code b...

Has anybody had the experience of Local Notifications being delivered from an app that has been uninstalled? I hesitate to ask since I can't reliably reproduce the issue, but we're receiving multiple reports of that occurring. We're having an emergency debug session here, and since we barely know where to start looking for answers on th...
When rebuilding a perfectly working iPhone project on iOS 4 SDK, I found out that fstat() returns a bogus value in the stat.st_size field. Observed on iPhone 3 simulator with iOS 4. Looks like there's a discrepancy between the binary layout of the stat structure in the program and in the API. I've found a workaround (lseek() to the end),...
Hi, I am using the SystemSound's framework to play sounds in my application. For devices with IOS3 it is working correctly. But recently I've updated the operating system to IOS4 and I am having a strange problem with the volume. Now I can't change the volume of my sounds during the game, it seems that this framework is using the ring v...

Currently iOS supports three different art sizes: art for the 480x320 original iPhone screen, art for the hi-res 960x640 iPhone 4 screen, and art for the 1024x768 iPad screen, which in my experience is usually not the same as for the hi-res screen because of the different demands placed upon the different aspect ratio of the screen. In ...
Hi All, I developed a complete application using xcode 3.2.2 and now want submit it to app store. Before that I need to compile it using xcode 3.2.3 for iOS 4.0. I opened the xcode 3.2.2 project in Xcode 3.2.3 and tried to run on device with OS4.0, It gives me an error.. "Error from debugger: The program being debugged is not bei...
Having recently installed the 4.0 SDK, I recompiled a client project to test how it would run under the new OS. (Previously testing with 3.1.3 had no crashes and only one memory leak, duly reported to Apple, who were unable to reproduce on 4.0 beta 3, and so closed.) Everything went very smoothly (no crashes during testing) until I deci...
Right, this may not be possible but maybe it it... I have 3 UIViewControllers, each with their own XIB files which contain the layout for each slide of a presentation (each slide will contain video, images, other interactive elements). I have hooked them all up to a UIScrollView by adding them one by one, see below: page1 *vc = [[page1...
In simple terms I have a view with three buttons; buttonOne buttonTwo checkButtonStatus if buttonOne is clicked it sets its own selected status to yes and buttonTwo selected status to no. Clicking buttonTwo does the opposite. Both buttonOne and buttonTwo by default are not selected. The third button (checkButtonStatus) should perfor...
It seems that in iOS4 the GPS updates are recieved with a 3-5 sec lag compared to the behavior in iPhoneOS3. e.g I start changing my location and I only receive GPS updates after a few seconds. I stop moving and the location updates only stop coming after a few seconds. (GPS reception at its best. That's not the problem.) In iPhoneOS...
I have code that works great in 3.2 and earlier. The javascript from my UIWebView Load - never seems to execute... Any idea what changed with 4.0 that might cause a problem...? my current code has a bunch of javascript in the page to load and format - one of the things is a variable that indicates the javascript prep is done... I am ch...
Am I missing something here with Multitasking feature. I know we can execute a task in background, but what I really need is that task continues execution when app goes in background. So what I need is different than starting a new task in background. If images are being loaded in a view and user presses the home button to make the app g...
I ran across a very strange issue today when trying to upload an update to iTunes Connect for an app that I am "certifying" as iOS4 capable. Keep in mind that this is my 6th update for this app and I have never had to do this before (and I know this question typically falls under the n00b category, but bear with me here). Apple kept re...
If I am creating an iPhone app, is it worth trying to make sacrifices with functionality (e.g. with MPMoviePlayer) in the application and support previous versions of the OS? Are the majority of iPhone users running iOS 4? Will I lose out on a big portion of the market if I only support iOS 4? ...
Hi all, I am iPhone application developer, many people told me to join with the android application development, as it's future is far better comparing to iphone.

I have an idea for a pretty unusual alarm clock fir the iPhone. But as of now I have some thoughts on how to actually implement this. First off: forgetting about background services for now, how would I do the actual timer that fires the alarm etc? A separate thread? Or does the SDK include any nice alarm features I missed? Of cause I ne...
