ipad - 如何从 iPad 的 UITableview 中定义的 UITextview 中关闭键盘

Question

我是 iPad 编程的新手，我想知道如何从 UItablecell 中定义的 UItextview 中关闭键盘。我在单元格中定义了多个 TextView 。请帮助我提出适当的解决方案或您的建议。

Answer 1

发送文本查看消息 resignFirstResponder 键盘将消失。如果您需要关闭它以响应返回键，请考虑让您的 View Controller 采用 UITextViewDelegate 协议(protocol)。

[self.textViewInQuestion resignFirstResponder];

或者，您可以像这样将 endEditing: 消息发送到 TableView :

/*
  Attempt to resign first responder status on any textfields within 
  the view's hierarchy.
*/

[self.tableView endEditing:NO];


// OR we can....


/*
  Force text fields within the view's hierarchy to resign first responder.
  Textfield delegates cannot prevent this from happening so this is not 
  recommended if you need to perform field validation and prevent the user 
  from leaving the textfield.

  However sometimes it is useful to be able to force the resignation of the 
  first responder status even with validation so it goes both ways really.

[self.tableView endEditing:YES];
