以下是我如何做到这一点的，这是Sam Ho和Marcel W的回答，以及我自己对蹩脚代码的一些错误修复。我用的是UITableViewController。当键盘显示时，表格现在可以正确地调整大小。

1)在viewDidLoad我添加:

self.tableView.autoresizingMask = UIViewAutoresizingFlexibleHeight;

2)我忘记在viewWillAppear和awakeFromNib中调用超等价物。我把这些加回来了。

我的方法:

我首先子类化UITextField并添加一个indexPath属性。在牢房里因为…方法我交出indexPath属性。

然后我添加以下代码:

UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:textField.indexPath];

CGPoint cellPoint = [cell convertPoint:textField.center toView:self.tableView];
[UIView animateWithDuration:0.3 animations:^(void){self.tableView.contentOffset = CGPointMake(0, cellPoint.y-50);}];

textFieldShould/WillBegin…等等。

当键盘消失时，你必须反转它:

[UIView animateWithDuration:0.3 animations:^(void){self.tableView.contentOffset = CGPointMake(0, 0);}];

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) })}
}

另一个简单的方法(只适用于一个部分)

//cellForRowAtIndexPath
UItextField *tf;
[cell addSubview:tf];
tf.tag = indexPath.row;
tf.delegate = self;

//textFieldDidBeginEditing:(UITextField *)text
[[self.tableView scrollToRowsAtIndexPath:[NSIndexPath indexPathForRow:text.tag in section:SECTIONINTEGER] animated:YES];

我正在用这些，它们就像魔法一样管用:

我遇到了同样的问题，但注意到它只出现在一个视图中。所以我开始寻找不同的控制器。

我发现滚动行为设置在- (void)viewWillAppear:(BOOL)动画的超级实例。

所以一定要像这样实现:

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    // your code
}

不管你用的是UIViewController还是UITableViewController;通过将UITableView作为self的子视图来检查它。UIViewController中的视图。这是相同的行为。视图不允许滚动，如果调用[super viewWillAppear:animated];失踪了。
