问题 I do have a popup view controller generated programmatically without a storyboard from the main view controller and would like to dismiss it once the input is being introduced by the user with a Done button on a tool bar at the popupview controller. I have been trying to use a protrocoll to dismiss the popover but it does not work. I have been fostering and applying several suggestions found in internet but all gave the same negative result. Do I oversee something? Here is the relevant code:

I made a UIPopoverController , and it all works fine, the user can pick a photo, but when the user pushes "USE" button. the app cashes a says UIPopoverController dealloc] reached while popover is still visible here is the code: - (void)choosePhotoFromLibraryipad:(id)sender{ if(![popoverController isPopoverVisible]){ imagePicker = [[UIImagePickerController alloc] init];
