In my iPhone app I'd like to monitor if the user enters some particular geographycal regions at a time and act consequently. I now saw that with the new iOS 4 it is possible to register some interest regions (CLRegion) to a CLLocationManager, so it would do some job for me, but... I'd also need to dynamically change the set of the regio...
I read about the point/pixels bit in the apple documentation, but still things are not completely clear to me. What I try to accomplish is placing a toolbar just above the keypad that appears when a textview is touched. The way it was working before IOS4 was by placing the toolbar at position 0,480 and then let it come up by subtracting ...
Is it possible to have iOS4 specific code (ie the MKMapView overlays) in an application, build using 4.0, set the Deployment Target to 3.0, and still have it work so long as the iOS4 code isn't called on a 3.x device? I am trying to do that now, and only calling the iOS4 code if the device supports it, but I can't get it installed. GDB ...
I try to compile but it fails because it find a duplicated definition of class in one of the dependencies and in the main dependency. I googled a lot and i even found the cause of this, due to a bug in xcode and the optimization for amr6 and arm7 code. But i could't found how to solve this. Has anybody use the three20 library with iOS4 ?...

I'm (trying) to use HTTP-Live-Streaming in my app and after weeks of re-encoding it seems to work now without errors by the mediastream validator. On my latest iPod Touch (iOS 4.0) with WiFi the videostream loads in 1sec and switches to the highest bandwidth stream. On another test device iPhone 3G (iOS 3.0) with WiFi it takes up to 30...

Hi, I'm working on an iPhone iOS4 application that incorporates playing music from the user's iPod library. I also want to keep track of what songs have been played and be able to change the song randomly, even while in the background.

I have a view added on a scrollview(maxZoomScale = 1, minZoomScale=0.25). view-frame have a size of near-about(2000, 2000). I have written code for drawing a path(for ~8000 points) in the drawRect of the view. Whenever scrollview's zooming ends, i flagged the view's drawing. Now each time drawRect is called it consumes huge memory (~16MB...

I have been looking for a way to show the iPhone screen (not the simulator) on a monitor or projector for demo purposes. Previous SO post suggested jailbreak (Veency, iDemo/DemoGod, screensplitr) or simulator. Release notes iOS 3.2 (External Display Support) and iOS 4.0 (Inherited Improvements) mentions that it should be possible to con...
Here's my code (simplified a bit). I have an NSTimer firing every second which subtracts one from the countervariable. When the app goes in the background, I'm stopping the counter and saving the time the counter would reach zero into an NSDefault value. However, when restoring the app from background, when I subtract the current time ...

Also I can change directory to /private/var but not into /mobile and /mobile/applications which is where the application is. Bellow is my code. NSString *currentpath; fil...
Hi, I upgraded xcode to 3.2.3 and loaded an existing project I had created with a prior version of xcode. It seems to compile fine as I have set up the correct deployment target and base sdk. When I look under Groups & Files, the Framework group, the Framework files are red and are pointing to the old framework files which don't exist...
Hello, I'm trying to lay out a bunch of views as shown in this photo: Each view has sublayers whose backgroundColor produces the colours you see. The problem is that when the view is rotated, the sublayer doesn't anti-alias, so these ugly white specks appear (I confirmed that they are indeed the backgroundColor of the UIView) Is the...
