当弹出窗口内的文本字段触发键盘时，将表格视图滚动到弹出过度呈现文本字段

I have a UITableViewController with many cells, each cell contains four text fields vertical on each other, a pop over is presented by tapping on any text field, however, this pop over contains a text field when tapped the keyboard is fired and most likely the pop over will be shifted up to prevent the keyboard from hiding its text field (this is the default behavior of the pop over), but in the background (the dimmed view), the with many cells,
