这个解决方案为我工作，请注意这一行

[tableView setContentOffset:CGPointMake(0.0, activeField.frame.origin.y-kbSize.height+160) animated:YES];

您可以更改160值以使其与您的工作相匹配

- (void)keyboardWasShown:(NSNotification*)aNotification
{
    NSDictionary* info = [aNotification userInfo];
    CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
    CGRect bkgndRect = activeField.superview.frame;
                        bkgndRect.size.height += kbSize.height;
     [activeField.superview setFrame:bkgndRect];
     [tableView setContentOffset:CGPointMake(0.0, activeField.frame.origin.y-kbSize.height+160) animated:YES];
}

- (void)textFieldDidBeginEditing:(UITextField *)textField
{
   activeField = textField;
}
-(void)textFieldDidEndEditing:(UITextField *)textField
 {
     activeField = nil;
 }
// Called when the UIKeyboardWillHideNotification is sent
- (void)keyboardWillBeHidden:(NSNotification*)aNotification
{
    UIEdgeInsets contentInsets = UIEdgeInsetsZero;
    tableView.contentInset = contentInsets;
    tableView.scrollIndicatorInsets = contentInsets;
    NSDictionary* info = [aNotification userInfo];
    CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
    CGRect bkgndRect = activeField.superview.frame;
    //bkgndRect.size.height += kbSize.height;
    [activeField.superview setFrame:bkgndRect];
    [tableView setContentOffset:CGPointMake(0.0, activeField.frame.origin.y-kbSize.height) animated:YES];
}

简单快捷的解决方案。

我只要滚动到右边的单元格

    - (void)scrollViewDidScroll:(UIScrollView *)scrollView 

假设我知道表现在处于这个模式_keepMyCellOnTop &我知道选定单元格“_selectedCellIndex”或滚动到选定单元格

- (void)scrollViewDidScroll:(UIScrollView *)scrollView 
{

    if (_keepMyCellOnTop)
    {
        [self.tableView scrollToRowAtIndexPath:_selectedCellIndex atScrollPosition:UITableViewScrollPositionTop animated:NO];
    }
}

这将防止滚动。

将代码放在-(void) scrollViewDidEndScrollingAnimation:(UIScrollView *)scrollView中 结果是上下滚动吗

以下是我的解决方案，灵感来自iOS7日历应用程序的“事件编辑”屏幕。

该解决方案的关键之一是当用户滚动表格时键盘被取消。

实现:

1)添加属性，将存储选定的文本字段:

@property (strong) UITextField *currentTextField;

和BOOL变量，我们将使用它来检查当用户滚动表时是否需要隐藏键盘。

BOOL hideKeyboardOnScroll;

2)处理UITextField委托回调:

#pragma mark - UITextFieldDelegate

- (void) textFieldDidBeginEditing: (UITextField *) textField {
    self.currentTextField = textField;
}

- (void) textFieldDidEndEditing: (UITextField *) textField {
    self.currentTextField = nil;
}

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

    CGPoint newContentOffset = CGPointZero;
    if (tableView.contentSize.height > tableView.frame.size.height) {
        newContentOffset.y = MIN(tableView.contentOffset.y, tableView.contentSize.height - tableView.frame.size.height);
    }
    [tableView setContentOffset: newContentOffset animated: YES];

    return YES;
}

3)处理UIScrollViewDelegate方法来检查用户滚动视图。

#pragma mark - UIScrollViewDelegate

- (void) scrollViewDidScroll: (UIScrollView *) scrollView {
    if (hideKeyboardOnScroll == YES) {
        [self.currentTextField resignFirstResponder];
    }
}

4)在视图控制器的[viewWillAppear]方法中订阅键盘通知，并在[viewWillDisappear]方法中取消订阅。

- (void) viewWillAppear: (BOOL) animated {
    [super viewWillAppear: animated];

    [ [NSNotificationCenter defaultCenter] addObserver: self selector: @selector(keyboardWillShow:)
                                                  name: UIKeyboardWillShowNotification object: nil];
    [ [NSNotificationCenter defaultCenter] addObserver: self selector: @selector(keyboardWillHide:)
                                                  name: UIKeyboardWillHideNotification object: nil];
}

- (void) viewWillDisappear: (BOOL) animated {
    [super viewWillDisappear: animated];

    [ [NSNotificationCenter defaultCenter] removeObserver: self name: UIKeyboardDidShowNotification object: nil];
    [ [NSNotificationCenter defaultCenter] removeObserver: self name: UIKeyboardWillHideNotification object: nil];    
}

5)处理键盘通知:

- (void) keyboardWillShow: (NSNotification *) notification {
    CGRect keyboardFrame = [ [ [notification userInfo] objectForKey: UIKeyboardFrameBeginUserInfoKey] CGRectValue];

    // Find cell with textfield.
    CGRect textFieldFrame = [tableView convertRect: self.currentTextField.frame fromView: self.currentTextField];
    NSIndexPath *indexPath = [tableView indexPathForRowAtPoint: textFieldFrame.origin];
    UITableViewCell *cell = [tableView cellForRowAtIndexPath: indexPath];
    //

    // Shrink tableView size.
    CGRect tableViewFrame = tableView.frame;
    tableView.frame = CGRectMake(tableView.frame.origin.x, tableView.frame.origin.y, tableView.frame.size.width,
                             self.view.frame.size.height - tableView.frame.origin.y - keyboardFrame.size.height);
    //

    // Check if cell is visible in shrinked table size.
    BOOL cellIsFullyVisible = YES;
    if ( cell.frame.origin.y < tableView.contentOffset.y ||
        (cell.frame.origin.y + cell.frame.size.height) > (tableView.contentOffset.y + tableView.frame.size.height) ) {
        cellIsFullyVisible = NO;
    }
    //

    // If cell is not fully visible when scroll table to show cell;
    if (cellIsFullyVisible == NO) {
        CGPoint contentOffset = CGPointMake(tableView.contentOffset.x, CGRectGetMaxY(cell.frame) - tableView.frame.size.height);
        if (cell.frame.origin.y < tableView.contentOffset.y) {
            contentOffset.y = cell.frame.origin.y;
        }
        contentOffset.y = MAX(0, contentOffset.y);

        // For some reason [setContentOffset] is called without delay then
        // this code may not work for some cells. That why we call it with brief delay.
        dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.1 * NSEC_PER_SEC));
        dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
            [UIView animateWithDuration: 0.5 animations:^{
                [tableView setContentOffset: contentOffset animated: NO];
            } completion: ^(BOOL finished) {
                hideKeyboardOnScroll = YES;
            }];
        });
    } else {
        hideKeyboardOnScroll = YES;
    }
    //

    // Finally restore original table frame.
    tableView.frame = tableViewFrame;
    //
}

- (void) keyboardWillHide: (NSNotification *) notification {
    [super keyboardWillHide: notification];

    hideKeyboardOnScroll = NO;
}

    // Scroll the table view to see the TextField just above the keyboard
    if (self.actifText)
      {
        CGRect textFieldRect = [self.myTableView convertRect:self.actifText.bounds fromView:self.actifText];

    // Apply new size of table view
    self.myTableView.frame = frame;

    [UIView commitAnimations];

Swift 1.2+版本:

class ViewController: UIViewController, UITextFieldDelegate {
    @IBOutlet weak var activeText: UITextField!
    @IBOutlet weak var tableView: UITableView!

    override func viewDidLoad() {
        NSNotificationCenter.defaultCenter().addObserver(self,
            selector: Selector("keyboardWillShow:"),
            name: UIKeyboardWillShowNotification,
            object: nil)
        NSNotificationCenter.defaultCenter().addObserver(self,
            selector: Selector("keyboardWillHide:"),
            name: UIKeyboardWillHideNotification,
            object: nil)
    }

    func textFieldDidBeginEditing(textField: UITextField) {
        activeText = textField
    }

    func textFieldDidEndEditing(textField: UITextField) {
        activeText = nil
    }

    func keyboardWillShow(note: NSNotification) {
        if let keyboardSize = (note.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.CGRectValue() {
            var frame = tableView.frame
            UIView.beginAnimations(nil, context: nil)
            UIView.setAnimationBeginsFromCurrentState(true)
            UIView.setAnimationDuration(0.3)
            frame.size.height -= keyboardSize.height
            tableView.frame = frame
            if activeText != nil {
                let rect = tableView.convertRect(activeText.bounds, fromView: activeText)
                tableView.scrollRectToVisible(rect, animated: false)
            }
            UIView.commitAnimations()

我认为最好的方法是通过UITableViewController。

如果你想在UIViewController中创建一个UITableView，只需要用一个嵌入的UITableViewController创建一个ContentView，并在UIViewController的viedDidLoad中放入以下代码行:

self.tableView = ((UITableViewController*)self.childViewControllers[0]).tableView;
self.tableView.delegate = self;
self.tableView.dataSource = self;

容易,)
