Title Body

I am developing an iphone application where I directly use AVFoundation to capture videos via the camera. I've implemented a feature to enable the tap to focus function for a user. - (void) focus:(CGPoint) aPoint; { #if HAS_AVFF Class captureDeviceClass = NSClassFromString(@"AVCaptureDevice"); if (captureDeviceClass != nil) { AVCaptureDevice *device = [captureDeviceClass defaultDeviceWithMediaType:AVMediaTypeVideo]; if([device isFocusPointOfInterestSupported] && [device isFocusModeSupported:AVCaptureFocusModeAutoFocus]) { CGRect screenRect = [[UIScreen mainScreen] bounds]; double screenWidth = screenRect.size.width; double screenHeight = screenRect.size.height; double focus_x = aPoint.x/screenWidth; double focus_y = aPoint.y/screenHeight; if([device lockForConfiguration:nil]) { [device setFocusPointOfInterest:CGPointMake(focus_x,focus_y)]; [device setFocusMode:AVCaptureFocusModeAutoFocus]; if ([device isExposureModeSupported:AVCaptureExposureModeAutoExpose]){ [device setExposureMode:AVCaptureExposureModeAutoExpose]; } [device unlockForConfiguration]; } } } #endif } So far so good, but I am missing the feedback rectangle like in the photos app. Is there any way to tell the AVFoundation Framework to show this feedback rectangle or do I have to implement this feature myself?
