I have an app (a game) which saves data: game state, high scores, achievements, etc. Currently the app delegate does this on applicationWillTerminate:. After playing around with iPhone 4 for a bit, it seems that applications pretty much never terminate: they just run in the background forever, unless the user goes out of their way to q...
I don't fully understand Apple's iOS 4 model, I've been poring through documentation for hours, but I still appreciate some help. Do backgrounded iPhone apps ever quit? For example, when I close a location-tracking app such as Loopt, it will be backgrounded but will it subscribe to the OS's significant locations service? According to ap...
I am trying to create an app that scales up nicely on the iPhone 4. Currently most of it scales up perfectly, except for one crucial piece: the text that I draw inside a CALayer, inside its drawInContext: method. Here is my code: - (void)drawInContext:(CGContextRef)context { UIGraphicsPushContext(context); CGContextSetGrayFill...
I noticed in one of my apps that the activity indicator doesn't seem to work on an iPhone 4. It works fine on an old iPhone upgraded to iOS 4 just not on an iPhone 4. Does anyone know why it isn't working? ...
I've got some image generating code that uses UIGraphicsBeginImageContext(), UIGraphicsGetImageFromCurrentImageContext() and UIImagePNGRepresentation() to do some drawing, then save it to disk as a PNG for later use. Does UIImagePNGRepresentation() take into account scale? As in, if I have an image that is 20 points wide, will the resul...
Besides the obvious answer of "buy an iphone 4" (I'm in Australia so that's not possible at the moment) - is there an easy way of checking how your app looks on the new iPhone 4. I have a background image in my app which I want to check how it scales. Any suggestions? ...
I use the following code to getting images from the sprite. And it works fine everywhere except the iPhone 4 (HD version). - (UIImage *)croppedImage:(CGRect)rect { CGImageRef image = CGImageCreateWithImageInRect([self CGImage], rect); UIImage *result = [UIImage imageWithCGImage:image]; CGImageRelease(image); return resul...
Is there a method or property that allows you to set the brightness of the LED light on the iPhone 4? ...
I just want to be able to turn on the led light. Is there a simple way to do this, or am I going to need to, say, set up the phone to take a video, simulate it videoing with the light on, but not save the video? Something like that? Thanks. ...

I loaded some app projects that I had been developing using the iPhone 3.1.3 Simulator. Now I got the 4.0 package, and for some reason when I hit the home button of the simulator to go the home screen and then go back to the app, it's in the same position as I left it. Is this now standard? What if I don't want it to do this? I'd rat...
I know that the only way to turn on the flash and keep it on on iPhone 4 is by turning the video camera on. I'm not too sure of the code though. Here is what I am trying: -(IBAction)turnTorchOn { AVCaptureSession *captureSession = [[AVCaptureSession alloc] init]; AVCaptureDevice *videoCaptureDevice = [AVCaptureDevice defaultDeviceWithMe...

Hi all, I am creating a custom UITableViewCell class in my iPhone app, but I am unclear how to state the dimensions given that the iPhone 2G/3G/3GS and iPhone 4 have different resolution screens. Clearly, when I programmatically add an element, I'll use calculated coordinates based on the screen resolution, but when I am in interface...
Thanks to SO's search function blowing up whenever I enter "@2x", it's difficult to tell whether this has already been asked... I've been using colorWithPatternImage: to build tiled background images for my various views. However, these predictably look like trash when viewed on the new iPhone 4 display. So I've built @2x versions of ...
Hello The iPad and iPhone4 both are armv7 (not 6), and I'm curious to know how to specify two separate icon sizes given that the target architecture is exactly the same. Specifying two in a typical universal app is simple, however I'm not sure how to do this. I can't find it in the documentation, although it may be! (Sorry if it is; ...
