Im making iPhone app using frame, my frame is not in center and it repeats. I want to set in center and I hate when my frames repeats multiple times.
Im using following code:
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
// picker.delegate = self;
[picker setSourceType:UIImagePickerControllerSourceTypeCamera];
// creating overlayView
UIView* overlayView = [[UIView alloc] initWithFrame:picker.view.frame];
// letting png transparency be
overlayView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"f2.png"]];
[overlayView.layer setOpaque:NO];
overlayView.opaque = NO;
picker.showsCameraControls = NO;
picker.cameraOverlayView = overlayView;
//[self presentModalViewController:picker animated:YES];
[self presentViewController:picker animated:YES completion:nil];
Am I missing something ?
TNX in advance.
I'm not sure, what you are asking, but maybe changing from frame to bounds could solve you problem:
UIView* overlayView = [[UIView alloc] initWithFrame:picker.view.bounds];

How to bound iPhone camera inside a frame like below image.
Let the camera opens on full screen but the reading area will be only non blurred background in short i want to develop a screen shown in image.
I have tried this code but it is not working...
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
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
I'm using Camera API and invoking the camera.
I want to display a header (for branding) on the top of the camera preview. The header is a png image.
Is it possible? Any help appreciated.
Thanks in advance.
You set overlay view of camera.
Check below link. It will help you the solve the problem.

I want to give option for user to take a photo or upload one as his avatar in my app.
I believe there is no need to put two different buttons for that, so instead I would like to make the next scenario:
user clicks on "Add Picture" button and automatically UIImagePicker with source control - camera is presented.
But, I want to have shortcut for gallery in the corner, where user could click, get into gallery and search for pic he would use.
Here is the screenshot of what I need:
Part with red circle is important part.
How do I put it there?
(Initially it's not there)
There is no pre-build way to do this.
What you can do is to make an overlay for Camera View.
Bear in mind that you have to make different view for each device, as every device already has different positioning inside the CameraView.
One example would be this:
- (IBAction)addImage:(UIButton *)sender {
UIView* overlay = [[UIView alloc] initWithFrame:CGRectMake(20,self.view.frame.size.height-60 , 40, 40)];
overlay.opaque=NO;
overlay.backgroundColor = [UIColor clearColor];
UIButton* btnGallery = [[UIButton alloc]initWithFrame:CGRectMake(0,0 , 40, 40)];
[btnGallery setImage:[UIImage imageNamed:#"image_gallery"] forState:UIControlStateNormal];
btnGallery.backgroundColor = [UIColor whiteColor];
[overlay addSubview:btnGallery];
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.mediaTypes = #[(NSString *) kUTTypeImage];
imagePicker.allowsEditing = YES;
[imagePicker.view addSubview:overlay];
[btnGallery addTarget:self
action:#selector(openGallery)
forControlEvents:UIControlEventTouchUpInside];
_picker = imagePicker;
[self presentViewController:imagePicker
animated:YES
completion:nil];
}
-(void)openGallery
{
UIImagePickerController *gallery = [[UIImagePickerController alloc] init];
gallery.delegate = self;
gallery.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
gallery.mediaTypes = #[(NSString *) kUTTypeImage];
gallery.allowsEditing = YES;
_gallery = gallery;
[_picker presentViewController:gallery
animated:YES
completion:nil];
}
How to add the UIImagePickerController in the view ? If I add the image picker to the view, its show on the full screen. I need to show the on the centre of the view, But UIImagePickerController hide the navigation bar.
How add the UIImagePickerController in the view and also show the navigation bar ?

imagePicker.toolbarHidden = YES;
imagePicker.wantsFullScreenLayout = NO;

I need some for show the navigation bar while add the UIImagePickerController in the view. Thanks in advance.
If you are develop application for iPad then you can use popoverviewcontroller to show imagepickerviewcontroller with navigation bar
please see thie link :
How to use UIImagePickerController in iPad?
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];
I am trying to incorporate UIImagePickerController into my app by adding it through subview. But somehow I am unable to increase its height beyond a certain fixed size(the size in default camera app). Is there a way to increase the height? Like the "Fast camera" app does it.
Here is my code:
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.delegate = self;
[self.picker.view setFrame:CGRectMake(0, 65, 320, 444)];
[self.view addSubview:self.picker.view];
use cameraOverlayView property UIImagePickerController class for custom view
i don't know it exactly you want like.
try this one:
self.picker = [[UIImagePickerController alloc] init];
self.picker.sourceType = UIImagePickerControllerSourceTypeCamera;
self.picker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
self.picker.showsCameraControls = YES;
self.picker.delegate = self;
[self.picker.view setFrame:CGRectMake(0,0, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height)];
[self.navigationController.view addSubview:self.picker.view];
i checked it working good in my app.
Happy Coding...
