UITextField的键盘不会被忽略。不完全是 [英] UITextField's keyboard won't dismiss. No, really

问题描述

我在模态表格（iPad）中有一个表格视图，其中一个单元格包含一个UITextField。我的视图控制器持有对文本字段的引用，也是它的委托。

I have a table view in a modal form sheet (iPad), and one of the cells contains a UITextField. My view controller holds a reference to the text field and is also its delegate.

当文本字段命中Return时，我告诉它 -resignFirstResponder 里面的 -textFieldShouldReturn：。在另一种情况下，我想强制它结束编辑，所以我告诉整个表视图 -endEditing：YES 。然后我释放我对文本字段的本地引用，并重新加载行以用其他东西替换它。

When the text field hits Return, I tell it to -resignFirstResponder inside of -textFieldShouldReturn:. In another case, I want to force it to end editing, so I tell the whole table view to -endEditing:YES. Afterwards I release my local reference to the text field, and reload the row to replace it with something else.

在任何一种情况下键盘都不会消失。我不知道出了什么问题，我不确定如何进一步调试。我从来没有遇到任何其他文字编辑的粘性键盘问题 - 第一个响应者辞职总是表现得如预期。

The keyboard won't go away in either case. I don't know what's wrong, and I'm not sure how to debug further. I've never had a sticky keyboard problem with any other text editing I've done-- the firstResponder resignation has always behaved as expected.

有什么想法吗？谢谢。

推荐答案

实施 -disablesAutomaticKeyboardDismissal 并返回NO。 确实在iOS 6上运行，但您必须在正确的控制器中实现它。如果你有一个带有文本字段的子控制器的模态表单导航控制器，那就是需要方法实现的导航控制器，而不是子控件。

Implement -disablesAutomaticKeyboardDismissal and return NO. It does work on iOS 6, but you have to implement it in the right controller. If you have a modal form sheet navigation controller with a child controller that has text fields, it's the navigation controller that needs the method implementation, not the child.
