// 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];

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];
}

UITableViewController会自动进行滚动。 与使用UIViewController相比的区别是，当使用TableViewController时，你必须通过使用NavigationController以编程方式创建navbar - buttonitem。

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()
        }
    }
}

Swift最简单的解决方案:

override func viewDidLoad() {
    super.viewDidLoad()
    
    searchBar?.becomeFirstResponder()
    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(MyViewController.keyboardWillShow(_:)), name: UIKeyboardDidShowNotification, object: nil)
    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(MyViewController.keyboardWillHide(_:)), name: UIKeyboardDidHideNotification, object: nil)
}

deinit {
    NSNotificationCenter.defaultCenter().removeObserver(self)
}

func keyboardWillShow(notification: NSNotification) {
    if let userInfo = notification.userInfo {
        if let keyboardHeight = userInfo[UIKeyboardFrameEndUserInfoKey]?.CGRectValue.size.height {
            tableView.contentInset = UIEdgeInsetsMake(0, 0, keyboardHeight, 0)
        }
    }
}

func keyboardWillHide(notification: NSNotification) {
    UIView.animateWithDuration(0.2, animations: { self.table_create_issue.contentInset = UIEdgeInsetsMake(0, 0, 0, 0) })
    // For some reason adding inset in keyboardWillShow is animated by itself but removing is not, that's why we have to use animateWithDuration here
    }

Swift 4.2或更高版本

override func viewDidLoad() {
    super.viewDidLoad()
    searchBar?.becomeFirstResponder()
    NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardWillShow), name: UIResponder.keyboardDidShowNotification, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardWillHide), name: UIResponder.keyboardDidHideNotification, object: nil)
}

deinit {
    NotificationCenter.default.removeObserver(self)
}

 @objc func keyboardWillShow(notification: NSNotification) {
    if let userInfo = notification.userInfo {
            let keyboardHeight = (userInfo[UIResponder.keyboardFrameEndUserInfoKey] as AnyObject).cgRectValue.size.height
            accountSettingsTableView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: keyboardHeight, right: 0)
        
    }
}
@objc func keyboardWillHide(notification: NSNotification) {
    UIView.animate(withDuration: 0.2, animations: { self.accountSettingsTableView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0) })}
}

如果你使用Three20，那么使用autoresizesForKeyboard属性。只要在视图控制器的-initWithNibName:bundle方法中设置

self.autoresizesForKeyboard = YES

这涉及到:

监听键盘通知并调整表视图的框架 滚动到第一个响应器

搞定了。
