问题
I am showing a Modal Presentation View in a Navigation Controller by calling
[self.navigationController presentViewController:controllerA animated:YES completion:nil];
And I am dismissing the controllerA by calling
[self.presentingViewController dismissViewControllerAnimated:YES completion:nil]
After the dismiss is done the UITableView in in the previous navigationController does not scroll up and down where as it did before the presentViewController was called. Do I need to do something after dismiss to make the UITableView scroll again.
回答1:
The problem was that I had a Header View in the UITableView and I needed to uncheck the "Use Autolayout" (in the File Inspector section) from the Xib file as I was loading the Header from a Xib.
