C# example that shows how to trigger the iOS camera:
class RootViewController : UIViewController, IUINavigationControllerDelegate, IUIImagePickerControllerDelegate
{
public void OpenCamera()
{
var picker = new UIImagePickerController();
picker.@delegate = this;
picker.sourceType = UIImagePickerControllerSourceType.Camera;
presentViewController(picker) animated(true) completion(null);
}
public void imagePickerController(UIImagePickerController picker) didFinishPickingMediaWithInfo(NSDictionary info)
{
// picture was taken
}
public public void imagePickerControllerDidCancel(UIImagePickerController picker)
{
// user canceled
}
....
}
