UIImagePickerController startVideoCapture with custom overlay

Question

I am using UIImagePickerController with a custom overlay to record a video in my app. For the implementation of the UIImagePickerController, I have used the code from a grea

Answer 1

The problem is that the action you attach to the initWithBarButtonSystemItem call doesn't pass the UIImagePickerController instance along.

What I would do is set the UIImagePickerController as a property of your class and access that property from your action, like this:

In your .h:

@property (nonatomic, strong) UIImagePickerController *cameraUI;

In your .m:

- (BOOL) startCameraControllerFromViewController: (UIViewController*) controller
                           usingDelegate: (id <UIImagePickerControllerDelegate,
                                           UINavigationControllerDelegate>) delegate {

    ...

    self.cameraUI = [[UIImagePickerController alloc] init];

    ...

    UIBarButtonItem *RecordBarButtonItem = [[UIBarButtonItem alloc ] initWithBarButtonSystemItem:UIBarButtonSystemItemCamera target:self action:@selector(recordPressed)]; // Removed the ':'

    ...
}


- (void) recordPressed {
    NSLog(@"lets record");
    [self.cameraUI startVideoCapture]; 
}

Answer 2

Actually I've just quickly tested it in some code I've gotten open, the sender for your action on the button press is UIBarButtonItem *. So there's a couple of things you can do, you can either go down the root of

UIBarButtonItem *senderButton = (UIBarButtonItem *)sender; 
if(senderButton.image == UIBarButtonSystemItemCamera)
{
   //Handle behaviour
}

Or set the tag variable for each button and skip the image check and look at the tags instead, which might make the logic a bit easier.
