Usually when I need to resign first responder in the event of a background tap, I overwrite the <code>- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event</code> UIViewController method, and in there, I resign first responders. I'm not sure if this is possible using Interface Builder in one quick action.

Actually, I remember it now.

I need to use Touch Down with a type of <code>id</code> and call it <code>backgroundTap</code>. Thanks, myself. :P

blocks|key|4810979|text|我建议在背景视图中添加一个UIGestureRecognizer。像这样|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4810980|-+(void)viewDidLoad+{

I would recommend adding a UIGestureRecognizer to you background view. Like this

<pre><code>- (void)viewDidLoad {
 [super viewDidLoad];

 // Do whatever you want...

 UITapGestureRecognizer *screenTapped = [[UITapGestureRecognizer alloc] initWithTarget:self
 action:@selector(dismissKeyboard)];
 screenTapped.cancelsTouchesInView = NO;
 [self.view addGestureRecognizer:screenTapped];

}

- (void)dismissKeyboard {
 [self.view endEditing:YES];
}
</code></pre>

Now the keyboard will be dismissed when the user taps the background view.

Hope it helps!

Use button in background to click out..and write simple code for click EVENT TOUCH UP INSIDE 

<pre><code>-(IBAction)backgroundbuttonpress:(id)sender 

{

 [textField resignFirstResponder]; 

}
</code></pre>

connect action to button...and make sure that You have declared <code>UITextFieldDelegate</code> in .H file

I'm writing an app in which I want to dismiss the keyboard by clicking in the background. I know I need to type in the following code somewhere after dragging one of the "Sent Events" dots to somewhere on the view controller. Assume for this example that the text field is called textField.

<code>-(IBAction)backgroundTap:(id)sender {
 [textField resignFirstResponder];
}</code>

Which dot do I need to drag from in "Sent Events" and to where? I know that this is the code that will work, but I can never remember which dot to use and where to drop it on the screen.

Thank you!

What do I have to drag and to where in order to dismiss a keyboard with a tap on the background?

我正在编写一个应用程序，在这个应用程序中，我想通过点击背景来取消键盘。我知道在将其中一个“发送事件”点拖到视图控制器的某个位置后，需要在的某个位置输入以下代码。对于此示例，假设文本字段名为textField。-(IBAction)backgroundTap:(id)sender {     [textField res...

问我必须拖动什么和到哪里，才能在背景上取消一个带有点击的键盘？
