I have a tableView full of images. When a user taps on an image (within the cell), a viewController with a larger zoomable version of the image is called with a popover segue. W
please check, if you are calling reloadData in viewWillAppear or viewDidAppear. or if you are calling any reloadsection in either of these 2 methods.
reloadData
viewWillAppear
viewDidAppear
reloadsection
You can also validate these calls also in viewWillDisappear/viewDidDisappear methods too.
viewWillDisappear
viewDidDisappear
