我将把我的解决方案(或者QuickDialog的)扔进帽子里。基本上是等待动画到滚动。获得键盘动画JIT而不是神奇的数字会很好。

-(void)textFieldDidBeginEditing:(UITextField *)textField
{
    if (textField == self.emailTextField) {
        NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
        dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, 50 * USEC_PER_SEC);
        dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
            [self.tableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionTop animated:YES];
        });
    }
}

如果你使用uitableview来放置你的文本字段(来自Jeff Lamarche)，你可以像这样使用委托方法滚动tableview。

(注意:我的文本字段存储在一个数组中，索引与表视图中的行相同)

- (void) textFieldDidBeginEditing:(UITextField *)textField
    {

        int index;
        for(UITextField *aField in textFields){

            if (textField == aField){
                index = [textFields indexOfObject:aField]-1;
            }
        }

         if(index >= 0) 
            [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:index inSection:0] atScrollPosition:UITableViewScrollPositionTop animated:YES];

        [super textFieldDidBeginEditing:textField];
    }

我经常在我的项目中使用这个。这个解决方案适用于滚动视图，表视图或集合视图，它很容易设置。 它还自动连接键盘上的“下一步”按钮，在文本字段之间切换。

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,)

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) })}
}

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
