iphone，当触摸UITextField外部时关闭键盘 [英] iphone, dismiss keyboard when touching outside of UITextField

问题描述

我想知道当用户触摸UITextField外面时如何使键盘消失？

解决方案

您需要添加一个UITapGestureRecogniser并将其分配给视图，然后在文本字段上调用resign first responder

代码：

在viewDidLoad b
$ b

  UITapGestureRecognizer * tap = [[UITapGestureRecognizer alloc] initWithTarget：self action：@selector（dismissKeyboard） 
 
 [self.view addGestureRecognizer：tap]; 
   
 
 
 
  In dismissKeyboard： 
 
 $ b b 
   - （void）dismissKeyboard 
 {
 [aTextField resignFirstResponder]; 
} 
  
（其中aTextField是负责键盘的文本字段）
 
I'm wondering how to make the keyboard disappear when the user touches outside of the UITextField? 
解决方案
You'll need to add an UITapGestureRecogniser and assign it to the view, and then call resign first responder on the textfield on it's selector.

The code:

In viewDidLoad
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyboard)];

[self.view addGestureRecognizer:tap];
In dismissKeyboard:
-(void)dismissKeyboard 
{
    [aTextField resignFirstResponder];
}
(Where aTextField is the textfield that is responsible for the keyboard)
