How to open full screen camera in Xcode - iphone

Question

I am developing an app in which i need to keep open full screen camera open and also add a button on it(bottom right). I googled but couldn't find any healthy solution. Thanks in advance. Have a good day.
Edited
- (void) showCameraUI {
[self startCameraControllerFromViewController: self
usingDelegate: self];
}
- (BOOL) startCameraControllerFromViewController: (UIViewController*) controller
usingDelegate: (id <UIImagePickerControllerDelegate,
UINavigationControllerDelegate>) delegate {
if (([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeCamera] == NO)
|| (delegate == nil)
|| (controller == nil))
return NO;
NSLog(#"Start Camera Controller method...");
UIImagePickerController *cameraUI = [[UIImagePickerController alloc] init];
cameraUI.sourceType = UIImagePickerControllerSourceTypeCamera;
// Displays a control that allows the user to choose picture or
// movie capture, if both are available:
cameraUI.mediaTypes =
[UIImagePickerController availableMediaTypesForSourceType:
UIImagePickerControllerSourceTypeCamera];
// Hides the controls for moving & scaling pictures, or for
// trimming movies. To instead show the controls, use YES.
cameraUI.allowsEditing = NO;
cameraUI.delegate = delegate;
[controller presentModalViewController: cameraUI animated: YES];
return YES;
}
P.S: I also added UINavigationControllerDelegate,UIImagePickerControllerDelegate as protocol in header file, but its not still opening camera and show me default view of project.

you can simply capture image Using camera like bellow, i am using this bellow method in my code:-
-(void)btnCemeraOpen
{
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:picker animated:YES];
}
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[self dismissModalViewControllerAnimated:YES];
yourImageView.image = [info valueForKey:#"UIImagePickerControllerOriginalImage"];
if(yourImageView==nil)
{
}
else
{
//DO logic
}
return;
}
