I want to use custom camera overlay view. Below is the code for it.
imagePicker = [[UIImagePickerController alloc] init];
self.imagePicker.delegate = self;
self.imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
self.imagePicker.showsCameraControls = NO;
self.imagePicker.cameraDevice = UIImagePickerControllerCameraDeviceFront;
self.imagePicker.toolbarHidden = YES;
self.imagePicker.wantsFullScreenLayout = YES;
self.imagePicker.navigationBarHidden = YES;
self.imagePicker.cameraOverlayView = [self cameraOverlayView];
The issue is there is a black background at bottom and I don't get from where it is coming.
What is wrong in code?
Try cameraViewTransform for full screen.
CGFloat camScaleup = 2;
imagePicker.cameraViewTransform = CGAffineTransformScale(imagePicker.cameraViewTransform, camScaleup, camScaleup);

picker.cameraDevice = UIImagePickerControllerCameraDeviceRear;
picker.showsCameraControls = YES;
picker.navigationBarHidden = YES;
picker.view.frame = CGRectMake(0, 10, 200, 20); // NOT WORKING !!!
picker.toolbarHidden = YES;
picker.wantsFullScreenLayout = NO;
// picker.delegate = delegate;
CGAffineTransform transform = CGAffineTransformMakeTranslation(0.0f, 50.0f);
transform = CGAffineTransformScale(transform, 1.2f, 1.2f);
picker.cameraViewTransform = transform;
[self presentViewController:picker animated:YES completion:nil];
how do i do this?
Thanks in advance!
You have to create custom camera for that. As I can see in the image you need to scan barcode. For that you need to use
AVCaptureSession
AVCaptureVideoPreviewLayer
We can change of Use Video to Confirm words or other words on iOS video recording?
I think it's not possible to change the text .Since apple is not providing any methods or API to do that . But you can present a overlay view like below:
self.picker = [[UIImagePickerController alloc] init];
self.picker.sourceType = UIImagePickerControllerSourceTypeCamera;
self.picker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
self.picker.cameraDevice = UIImagePickerControllerCameraDeviceRear;
self.picker.showsCameraControls = NO;
self.picker.navigationBarHidden = YES;
self.picker.toolbarHidden = YES;
self.picker.wantsFullScreenLayout = YES;
// Insert the overlay
self.overlay = [[OverlayViewController alloc] initWithNibName:#"Overlay" bundle:nil];
self.overlay.pickerReference = self.picker;
self.picker.cameraOverlayView = self.overlay.view;
self.picker.delegate = self.overlay;
[self presentModalViewController:self.picker animated:NO];
Design Overlay view as per your requirement. You can also use storyboard to design the overlay view and refer that view controller alone .
Since you haven't mentioned the technology using . I have posted the code in Objective C
How to remove that black navigation bar on UIimage picker
we use video mode
already write code for hides the navigation bar and camera controls and toolbar
that is
picker = [[UIImagePickerController alloc] init];
picker.sourceType = sourceType;
picker.delegate = self;
picker.allowsEditing = NO;
picker.showsCameraControls = NO;
picker.cameraViewTransform = CGAffineTransformScale(imagePickerController.cameraViewTransform, 1, 1.32 );
Try this u can sole the issue
picker = [[UIImagePickerController alloc] init];
picker.sourceType = sourceType;
picker.delegate = self;
picker.allowsEditing = NO;
picker.showsCameraControls = NO;
as possible you can add this code:
picker.wantsFullScreenLayout = YES;
I am trying to create a custom camera overlay, but am having some problems. The capture view works great, but I would like to show another view where the user can edit the photo after the image is captured. The problem is that when a photo is taken, the view with the photo is automatically dismissed. How would I fix this so that I can show another view controller after the user takes a photo.
Here is how I create the picker:
self.cameraPicker = [[UIImagePickerController alloc] init];
self.cameraPicker.delegate = self;
self.cameraPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
self.cameraPicker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
self.cameraPicker.cameraDevice = UIImagePickerControllerCameraDeviceRear;
self.cameraPicker.showsCameraControls = NO;
self.cameraPicker.allowsEditing = YES;
self.cameraPicker.navigationBarHidden = YES;
self.cameraPicker.toolbarHidden = YES;
self.cameraPicker.videoQuality = UIImagePickerControllerQualityTypeIFrame1280x720;
self.frontFacing = NO;
self.gridShowing = NO;
self.showingFlash = NO;
// Insert the overlay
CameraOverlayView *overlay = [[CameraOverlayView alloc] initWithFrame:CGRectMake(0, 0, 320, 568)];
self.cameraPicker.cameraOverlayView = overlay;
overlay.delegate = self;
[self.navigationController presentViewController:(UIViewController *)self.cameraPicker animated:YES completion:nil];
Here is how I take the photo, after this is called, the viewController is dismissed:
, which I do not want:
[self.cameraPicker takePicture];

Correct way to customize media capture here using Assets Library.
Simple way (in some cases) is using overlay view with frame size of whole screen and add controls on that view which simulate navigation bar.
if (_pickerOverlay == nil) {
_pickerOverlay = [[UIView alloc] initWithFrame:self.view.bounds];
//red transparent tint for demo
_pickerOverlay.backgroundColor = [UIColor colorWithRed:1.0
green:0.0
blue:0.0 alpha:0.6];
UIButton *btnBack = [UIButton buttonWithType:UIButtonTypeSystem];
btnBack.frame = CGRectMake(20, 20, 250, 40);
[btnBack setTitle:#"Custom buttom" forState:UIControlStateNormal];
btnBack.backgroundColor = [UIColor whiteColor];
[_pickerOverlay addSubview:btnBack];
}
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.showsCameraControls = NO;
picker.cameraOverlayView = _pickerOverlay;
[self presentViewController:picker animated:YES completion:nil];
