结合并填写几个答案(特别是Ortwin Gentz，用户98013)和另一篇文章中的空白，这将适用于iPad上的SDK 4.3的纵向或横向模式:

@implementation UIView (FindFirstResponder)
- (UIResponder *)findFirstResponder
{
  if (self.isFirstResponder) {        
    return self;     
  }

  for (UIView *subView in self.subviews) {
    UIResponder *firstResponder = [subView findFirstResponder];
    if (firstResponder != nil) {
      return firstResponder;
    }
  }

  return nil;
}
@end

@implementation MyViewController

    // we don't use SDK constants here to be universally compatible with all SDKs ≥ 3.0
    NSValue* keyboardFrameValue = [userInfo objectForKey:@"UIKeyboardBoundsUserInfoKey"];

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,)

我在做一些非常相似的事情它是通用的，不需要为你的代码计算特定的东西。 只需检查代码上的注释:

在MyUIViewController.h

@interface MyUIViewController: UIViewController <UITableViewDelegate, UITableViewDataSource>
{
     UITableView *myTableView;
     UITextField *actifText;
}

@property (nonatomic, retain) IBOutlet UITableView *myTableView;
@property (nonatomic, retain) IBOutlet UITextField *actifText;

- (IBAction)textFieldDidBeginEditing:(UITextField *)textField;
- (IBAction)textFieldDidEndEditing:(UITextField *)textField;

-(void) keyboardWillHide:(NSNotification *)note;
-(void) keyboardWillShow:(NSNotification *)note;

@end

在MyUIViewController.m

@implementation MyUIViewController

@synthesize myTableView;
@synthesize actifText;

- (void)viewDidLoad 
{
    // Register notification when the keyboard will be show
    [[NSNotificationCenter defaultCenter] addObserver:self
                                          selector:@selector(keyboardWillShow:)
                                          name:UIKeyboardWillShowNotification
                                          object:nil];

    // Register notification when the keyboard will be hide
    [[NSNotificationCenter defaultCenter] addObserver:self
                                          selector:@selector(keyboardWillHide:)
                                          name:UIKeyboardWillHideNotification
                                          object:nil];
}

// To be link with your TextField event "Editing Did Begin"
//  memoryze the current TextField
- (IBAction)textFieldDidBeginEditing:(UITextField *)textField
{
    self.actifText = textField;
}

// To be link with your TextField event "Editing Did End"
//  release current TextField
- (IBAction)textFieldDidEndEditing:(UITextField *)textField
{
    self.actifText = nil;
}

-(void) keyboardWillShow:(NSNotification *)note
{
    // Get the keyboard size
    CGRect keyboardBounds;
    [[note.userInfo valueForKey:UIKeyboardFrameBeginUserInfoKey] getValue: &keyboardBounds];

    // Detect orientation
    UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
    CGRect frame = self.myTableView.frame;

    // Start animation
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationBeginsFromCurrentState:YES];
    [UIView setAnimationDuration:0.3f];

    // Reduce size of the Table view 
    if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown)
        frame.size.height -= keyboardBounds.size.height;
    else 
        frame.size.height -= keyboardBounds.size.width;

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

    // 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];
        [self.myTableView scrollRectToVisible:textFieldRect animated:NO];
      }

    [UIView commitAnimations];
}

-(void) keyboardWillHide:(NSNotification *)note
{
    // Get the keyboard size
    CGRect keyboardBounds;
    [[note.userInfo valueForKey:UIKeyboardFrameBeginUserInfoKey] getValue: &keyboardBounds];

    // Detect orientation
    UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
    CGRect frame = self.myTableView.frame;

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationBeginsFromCurrentState:YES];
    [UIView setAnimationDuration:0.3f];

    // Increase size of the Table view 
    if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown)
        frame.size.height += keyboardBounds.size.height;
    else 
        frame.size.height += keyboardBounds.size.width;

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

    [UIView commitAnimations];
}

@end

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()
        }
    }

    func keyboardWillHide(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
            UIView.commitAnimations()
        }
    }
}

不需要任何计算，使用下面的代码，它将工作: 这段代码我用在我的自定义UITableviewcell，它是工作的:

override func viewDidLoad() {
super.viewDidLoad()

NotificationCenter.default.addObserver(self, selector: #selector(ViewController.keyboardWillShow), name: NSNotification.Name.UIKeyboardWillShow, object: nil)

NotificationCenter.default.addObserver(self, selector: #selector(ViewController.keyboardWillHide), name: NSNotification.Name.UIKeyboardWillHide, object: nil)}


func keyboardWillShow(_ notification:Notification) {

if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
    tableView.contentInset = UIEdgeInsetsMake(0, 0, keyboardSize.height, 0)
}}


func keyboardWillHide(_ notification:Notification) {

if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
    tableView.contentInset = UIEdgeInsetsMake(0, 0, 0, 0)
}}

// 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];

执行滚动的函数可以简单得多:

- (void) textFieldDidBeginEditing:(UITextField *)textField {
    UITableViewCell *cell;

    if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1) {
    // Load resources for iOS 6.1 or earlier
        cell = (UITableViewCell *) textField.superview.superview;

    } else {
        // Load resources for iOS 7 or later
        cell = (UITableViewCell *) textField.superview.superview.superview; 
       // TextField -> UITableVieCellContentView -> (in iOS 7!)ScrollView -> Cell!
    }
    [tView scrollToRowAtIndexPath:[tView indexPathForCell:cell] atScrollPosition:UITableViewScrollPositionTop animated:YES];
}

就是这样。根本不需要计算。
