如何在返回按钮点击> iphone上隐藏UIViewController中的键盘 [英] how to hide keyboard in UIViewController on return button click->iphone

问题描述

嗨我发现了一些像这样的问题，但他们谈的是textView，我有ViewController，有scrollView，其中有6个textfield和一个textView，我想要一个功能，让键盘在完成/返回按钮点击时消失。我执行的功能辞职到第一响应者，当我点击scrollView外面时隐藏我的键盘，但这不是我想要的，因为我喜欢让它在点击按钮时消失。

Hi I find some questions like that but they talk about textView, I have ViewController, with scrollView where are 6 textfield and one textView I want a function which makes the keyboard disappear on on done/return button click.I implemented functions resign to first responder, which hide my keyboard when i click outside of scrollView, but that is not exactly i want, because i like to make it disappear on button click too.

任何帮助的谢谢

推荐答案

设置一个符合UITextFieldDelegate协议的类，并使文本字段的委托成为这个班。实现方法：

Set up a class that conforms to the UITextFieldDelegate protocol and make the delegate of your text fields an instance of this class. Implement the method:

- (BOOL)textFieldShouldReturn:(UITextField *)textField

如下：

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
    return YES;
}
