Question

Iam using the following code for taking the picture automatically from IPAD front camera:

UIImagePickerController *imgPkr = [[UIImagePickerController alloc] init];
        imgPkr.sourceType = UIImagePickerControllerSourceTypeCamera;
        imgPkr.delegate = self;

        imgPkr.cameraDevice=UIImagePickerControllerCameraDeviceFront;
        [self presentModalViewController:imgPkr animated:YES];
        imgPkr.showsCameraControls = NO;
        [imgPkr takePicture];

But this code Dont take any picture and dont call the delegate:

    -(void)imagePickerController:(UIImagePickerController*)picker
didFinishPickingMediaWithInfo:(NSDictionary*)info

Any idea what is wrong with the code

Answer 1

My first guess is that [imgPkr takePicture]; is being called before the picker is done being presented. Try it like this:

UIImagePickerController *imgPkr = [[UIImagePickerController alloc] init];
        imgPkr.sourceType = UIImagePickerControllerSourceTypeCamera;
        imgPkr.delegate = self;

        imgPkr.cameraDevice=UIImagePickerControllerCameraDeviceFront;
        [self presentModalViewController:imgPkr animated:YES];
        imgPkr.showsCameraControls = NO;
        [self performSelector:@selector(takePicture) withObject:self afterDelay:1.0];

OR

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(takePicture)
                                             name:AVCaptureSessionDidStartRunningNotification 

object:nil];

&

- (void)takePicture
{
    [imgPkr takePicture];
}
