If your image picker is being presented modally, you may need to dismiss it first and THEN you can display your custom view controller. Something like this:
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[self dismissViewControllerAnimated:YES completion:^{
UIStoryboard *sb = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
DAAnalysisViewController *asdf = [sb instantiateViewControllerWithIdentifier:@"1"];
[self presentViewController:asdf animated:YES completion:nil];
}];
}
