一个更加流线型的解决方案。它滑入UITextField委托方法，所以它不需要搞砸/ UIKeyboard通知。

实现注意事项:

kSettingsRowHeight——UITableViewCell的高度。

offsetTarget和offsetThreshold基于kSettingsRowHeight。如果使用不同的行高，则将这些值设置为point的y属性。[alt:以不同的方式计算行偏移量。]

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
CGFloat offsetTarget    = 113.0f; // 3rd row
CGFloat offsetThreshold = 248.0f; // 6th row (i.e. 2nd-to-last row)

CGPoint point = [self.tableView convertPoint:CGPointZero fromView:textField];

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.2];
[UIView setAnimationCurve:UIViewAnimationCurveEaseOut];

CGRect frame = self.tableView.frame;
if (point.y > offsetThreshold) {
    self.tableView.frame = CGRectMake(0.0f,
                      offsetTarget - point.y + kSettingsRowHeight,
                      frame.size.width,
                      frame.size.height);
} else if (point.y > offsetTarget) {
    self.tableView.frame = CGRectMake(0.0f,
                      offsetTarget - point.y,
                      frame.size.width,
                      frame.size.height);
} else {
    self.tableView.frame = CGRectMake(0.0f,
                      0.0f,
                      frame.size.width,
                      frame.size.height);
}

[UIView commitAnimations];

return YES;

}

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];

[UIView beginAnimations:nil context:nil];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:0.2];
[UIView setAnimationCurve:UIViewAnimationCurveEaseOut];

CGRect frame = self.tableView.frame;
self.tableView.frame = CGRectMake(0.0f,
                  0.0f,
                  frame.size.width,
                  frame.size.height);

[UIView commitAnimations];

return YES;

}

这非常有效，在iPad上也是如此。

- (BOOL)textFieldShouldReturn:(UITextField *)textField 
{

    if(textField == textfield1){
            [accountName1TextField becomeFirstResponder];
        }else if(textField == textfield2){
            [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:1] atScrollPosition:UITableViewScrollPositionTop animated:YES];
            [textfield3 becomeFirstResponder];

        }else if(textField == textfield3){
            [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:1 inSection:1] atScrollPosition:UITableViewScrollPositionTop animated:YES];
            [textfield4 becomeFirstResponder];

        }else if(textField == textfield4){
            [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:2 inSection:1] atScrollPosition:UITableViewScrollPositionTop animated:YES];
            [textfield5 becomeFirstResponder];

        }else if(textField == textfield5){
            [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:3 inSection:1] atScrollPosition:UITableViewScrollPositionTop animated:YES];
            [textfield6 becomeFirstResponder];

        }else if(textField == textfield6){
            [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:4 inSection:1] atScrollPosition:UITableViewScrollPositionTop animated:YES];
            [textfield7 becomeFirstResponder];

        }else if(textField == textfield7){
            [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:5 inSection:1] atScrollPosition:UITableViewScrollPositionTop animated:YES];
            [textfield8 becomeFirstResponder];

        }else if(textField == textfield8){
            [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:6 inSection:1] atScrollPosition:UITableViewScrollPositionTop animated:YES];
            [textfield9 becomeFirstResponder];

        }else if(textField == textfield9){
            [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:7 inSection:1] atScrollPosition:UITableViewScrollPositionTop animated:YES];
            [textField resignFirstResponder];
        }

因为你在一个表格中有文本字段，最好的方法是调整表格的大小——你需要设置tableView.frame的高度比键盘的大小小(我认为大约165像素)，然后当键盘被关闭时再次展开它。

如果你不想让用户滚动，你也可以选择在那个时候禁用tableView的用户交互。

// scroll tableview so content ends at the middle of the tableview (out of the way of the keyboard)
CGPoint newContentOffset = CGPointMake(0, [self.tableView contentSize].height - (self.tableView.bounds.size.height / 2));
[self.tableView setContentOffset:newContentOffset animated:YES];

使用UITextField的委托方法:

斯威夫特

func textFieldShouldBeginEditing(textField: UITextField) -> bool {
  let txtFieldPosition = textField.convertPoint(textField.bounds.origin, toView: yourTableViewHere)
  let indexPath = yourTablViewHere.indexPathForRowAtPoint(txtFieldPosition)
  if indexPath != nil {
     yourTablViewHere.scrollToRowAtIndexPath(indexPath!, atScrollPosition: .Top, animated: true)
  }
  return true
}

objective - c

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
  CGPoint txtFieldPosition = [textField convertPoint:CGPointZero toView: yourTablViewHere];
  NSLog(@"Begin txtFieldPosition : %@",NSStringFromCGPoint(txtFieldPosition));
  NSIndexPath *indexPath = [yourTablViewHere indexPathForRowAtPoint:txtFieldPosition];

  if (indexPath != nil) {
     [yourTablViewHere scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionMiddle animated:YES];
  }
  return YES;
}

如果你使用uitableview来放置你的文本字段(来自Jeff Lamarche)，你可以像这样使用委托方法滚动tableview。

(注意:我的文本字段存储在一个数组中，索引与表视图中的行相同)

- (void) textFieldDidBeginEditing:(UITextField *)textField
    {

        int index;
        for(UITextField *aField in textFields){

            if (textField == aField){
                index = [textFields indexOfObject:aField]-1;
            }
        }

         if(index >= 0) 
            [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:index inSection:0] atScrollPosition:UITableViewScrollPositionTop animated:YES];

        [super textFieldDidBeginEditing:textField];
    }
