简单的解决方案和最新的动画api。将origin.y更改215，您可以将其自定义为适合您的值。

- (void)textFieldDidBeginEditing:(UITextField *)textField
{
    if (self.view.frame.origin.y >= 0) {

        [UIView animateWithDuration:0.5 animations:^{
           self.view.frame = CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y-215, self.view.frame.size.width, self.view.frame.size.height);
       }];
   }
}

- (void)textFieldDidEndEditing:(UITextField *)textField
{
    if (self.view.frame.origin.y < 0) {
        [UIView animateWithDuration:0.5 animations:^{
           self.view.frame = CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y+215, self.view.frame.size.width, self.view.frame.size.height);
        }];

    }
}

如果该文本字段位于表的单元格中（即使table.scrollable=NO），也可以轻松自动完成。

注意：桌子的位置和大小必须合理。例如：如果桌子的y位置是从视图底部算起的100，那么300高的键盘将覆盖整个桌子。如果表的高度为10，并且当键盘出现时，其中的文本字段必须向上滚动100才能可见，那么该文本字段将超出表的范围。

本文档详细介绍了此问题的解决方案。查看“移动位于键盘下的内容”下的源代码。这很简单。

编辑：注意到示例中有一个小故障。您可能希望侦听UIKeyboardWillHideNotification，而不是UIKeyboard DidHideNotification。否则，在键盘关闭动画期间，键盘后面的滚动视图将被剪裁。

已经有很多答案了，但上面的解决方案仍然没有一个具备“完美”无bug、向后兼容和无闪烁动画所需的所有花哨定位功能。（在一起设置帧/边界和contentOffset动画时出错，界面方向不同，iPad分割键盘等）让我分享我的解决方案：（假设您已设置UIKeyboardWill（显示|隐藏）通知）

// Called when UIKeyboardWillShowNotification is sent
- (void)keyboardWillShow:(NSNotification*)notification
{
    // if we have no view or are not visible in any window, we don't care
    if (!self.isViewLoaded || !self.view.window) {
        return;
    }

    NSDictionary *userInfo = [notification userInfo];

    CGRect keyboardFrameInWindow;
    [[userInfo objectForKey:UIKeyboardFrameEndUserInfoKey] getValue:&keyboardFrameInWindow];

    // the keyboard frame is specified in window-level coordinates. this calculates the frame as if it were a subview of our view, making it a sibling of the scroll view
    CGRect keyboardFrameInView = [self.view convertRect:keyboardFrameInWindow fromView:nil];

    CGRect scrollViewKeyboardIntersection = CGRectIntersection(_scrollView.frame, keyboardFrameInView);
    UIEdgeInsets newContentInsets = UIEdgeInsetsMake(0, 0, scrollViewKeyboardIntersection.size.height, 0);

    // this is an old animation method, but the only one that retains compaitiblity between parameters (duration, curve) and the values contained in the userInfo-Dictionary.
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:[[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue]];
    [UIView setAnimationCurve:[[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] intValue]];

    _scrollView.contentInset = newContentInsets;
    _scrollView.scrollIndicatorInsets = newContentInsets;

    /*
     * Depending on visual layout, _focusedControl should either be the input field (UITextField,..) or another element
     * that should be visible, e.g. a purchase button below an amount text field
     * it makes sense to set _focusedControl in delegates like -textFieldShouldBeginEditing: if you have multiple input fields
     */
    if (_focusedControl) {
        CGRect controlFrameInScrollView = [_scrollView convertRect:_focusedControl.bounds fromView:_focusedControl]; // if the control is a deep in the hierarchy below the scroll view, this will calculate the frame as if it were a direct subview
        controlFrameInScrollView = CGRectInset(controlFrameInScrollView, 0, -10); // replace 10 with any nice visual offset between control and keyboard or control and top of the scroll view.

        CGFloat controlVisualOffsetToTopOfScrollview = controlFrameInScrollView.origin.y - _scrollView.contentOffset.y;
        CGFloat controlVisualBottom = controlVisualOffsetToTopOfScrollview + controlFrameInScrollView.size.height;

        // this is the visible part of the scroll view that is not hidden by the keyboard
        CGFloat scrollViewVisibleHeight = _scrollView.frame.size.height - scrollViewKeyboardIntersection.size.height;

        if (controlVisualBottom > scrollViewVisibleHeight) { // check if the keyboard will hide the control in question
            // scroll up until the control is in place
            CGPoint newContentOffset = _scrollView.contentOffset;
            newContentOffset.y += (controlVisualBottom - scrollViewVisibleHeight);

            // make sure we don't set an impossible offset caused by the "nice visual offset"
            // if a control is at the bottom of the scroll view, it will end up just above the keyboard to eliminate scrolling inconsistencies
            newContentOffset.y = MIN(newContentOffset.y, _scrollView.contentSize.height - scrollViewVisibleHeight);

            [_scrollView setContentOffset:newContentOffset animated:NO]; // animated:NO because we have created our own animation context around this code
        } else if (controlFrameInScrollView.origin.y < _scrollView.contentOffset.y) {
            // if the control is not fully visible, make it so (useful if the user taps on a partially visible input field
            CGPoint newContentOffset = _scrollView.contentOffset;
            newContentOffset.y = controlFrameInScrollView.origin.y;

            [_scrollView setContentOffset:newContentOffset animated:NO]; // animated:NO because we have created our own animation context around this code
        }
    }

    [UIView commitAnimations];
}


// Called when the UIKeyboardWillHideNotification is sent
- (void)keyboardWillHide:(NSNotification*)notification
{
    // if we have no view or are not visible in any window, we don't care
    if (!self.isViewLoaded || !self.view.window) {
        return;
    }

    NSDictionary *userInfo = notification.userInfo;

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:[[userInfo valueForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue]];
    [UIView setAnimationCurve:[[userInfo valueForKey:UIKeyboardAnimationCurveUserInfoKey] intValue]];

    // undo all that keyboardWillShow-magic
    // the scroll view will adjust its contentOffset apropriately
    _scrollView.contentInset = UIEdgeInsetsZero;
    _scrollView.scrollIndicatorInsets = UIEdgeInsetsZero;

    [UIView commitAnimations];
}

在更改文本字段或编辑其内容时，我遇到了重新设置为默认主视图的问题（例如，电话文本字段和添加“-”符号，视图返回覆盖文本字段）我最终通过使用自动布局和更改约束常量（而不是通知代理函数中的帧大小或位置）来克服这一问题，如下所示：

另外，我并没有使用滚动视图，只是简单地向上移动视图，但它的工作原理应该类似

func keyboardWillShow(notification: NSNotification) {
if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
    if !keyboardIsShown{
        self.infoViewTopConstraint.constant -= keyboardSize.height
        self.infoViewBottomConstraint.constant += keyboardSize.height
        self.view.setNeedsLayout()
        self.view.layoutIfNeeded()
        keyboardIsShown = true
    }
}

func keyboardWillHide(notification: NSNotification) {
if keyboardIsShown {
    self.infoViewTopConstraint.constant += keyboardSize.height
    self.infoViewBottomConstraint.constant -= keyboardSize.height
    self.view.setNeedsLayout()
    self.view.layoutIfNeeded()
    keyboardIsShown = false
}

非常轻量级的解决方案可以使用KeyboardAnimator。

项目获得了示例实现，文档编制仍在进行中。。。

适当用法：它具有UITextField和UITextView的特定实现

限制：：它完全基于objective-c，swift版本将很快推出。
