Hi,I'm having some issues locking the focus and taking a flash photo on iPhone 10 (iOS 12.0). I've made the simplest camera app I can that turns Flash on using a AVCapturePhotoSettings object, locks focus on the AVCaptureDevice using [device setFocusMode:AVCaptureFocusModeLocked]; and then takes a picture using capturePhotoWithSettings.Regardless of the focus lock, auto focus still often happens, particularly when the preview is out of focus. Am I missing a settings, or a new way to lock focus? I have no issues on the iPhone 6 with this code.This is essentially the full app (i have dropped most the error checking in this example, but no errors pop up):// ViewController.h //#import //@interface ViewController : UIViewController //@end #import #import ViewController.h @interface ViewController () @property (nonatomic) AVCaptureSession *session; @property (nonatomic) AVCapturePhotoOutput *stillImageOutput; @property (nonatomic) AVCaptureVideoPreviewLayer *videoPreviewLayer; @p
