Camera focus square for iPhone iOS 4.3 - is it removed programmatically?

Question

Since my friend upgraded his iPhone iOS to 4.3, a small square has appeared that appears every time he takes a picture with the camera. We are developing an application that uses a camera and would like to remove this annoying square. I did not find anything about this in the Apple UIImagePickerController documentation. The square did not exist in previous versions of iOS.

You can try to lock focus to turn off autofocus. Here is a sample code:

NSArray *devices = [AVCaptureDevice devices]; NSError *error; for (AVCaptureDevice *device in devices) { if (([device hasMediaType:AVMediaTypeVideo]) && ([device position] == AVCaptureDevicePositionBack) ) { [device lockForConfiguration:&error]; if ([device isFocusModeSupported:AVCaptureFocusModeLocked]) { device.focusMode = AVCaptureFocusModeLocked; NSLog(@"Focus locked"); } [device unlockForConfiguration]; } }

Setting the .showsCameraControls property of your selection controller to NO should remove the focus square (this was done before 4.3, I don’t think something has changed), but the disadvantage is that you will need to provide your own (for photographing, etc. .). Is that all or nothing I'm afraid of!

Custom overlay and overlay creation are not displayed by default. You can make your overlay completely empty.
