Question

In order to make my custom UIImagePickerSourceTypeCamera, I had to do this:

pickerOne = [[UIImagePickerController alloc] init];
pickerOne.delegate = self;
pickerOne.sourceType = UIImagePickerControllerSourceTypeCamera;
pickerOne.showsCameraControls = NO;
pickerOne.navigationBarHidden = YES;
pickerOne.toolbarHidden = YES;
pickerOne.wantsFullScreenLayout = YES;

But now, when I take a picture like this:

[cameraButton addTarget:pickerOne 
                 action:@selector(takePicture)
       forControlEvents:UIControlEventTouchUpInside];

it doesn’t show the shutter when you take the picture. Is there a way to show it programmatically?

Answer 1

It is possible. The trick is to do the following:

Enable the camera controls on initializing the picker (this will enable the shutter view).

pickerOne.showsCameraControls = YES;

Overlay the camera controls with your own view which has the cameraButton

In your takePicture: method do the following:

pickerOne.showsCameraControls = NO;
[[NSRunLoop currentRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:0.0]];
[pickerOne takePicture];

In the imagePickerController:didFinishPickingMediaWithInfo: method do the following:

pickerOne.showsCameraControls = YES;  // perform on main thread
