Move view when so that keyboard does not hide text field

Question

In my app, when I click on a text field, the keyboard hides it. Please help me -- how can I move my view up when I click on the text field. I'm using this code in textFieldDidBeginEditing:

self.tableView.scrollIndicatorInsets = UIEdgeInsetsMake(0, 0, 216, 0);
self.tableView.contentInset = UIEdgeInsetsMake(0, 0, 216, 0);

but it doesn't work.
