blocks|key|2402270|text|要做到这一点，最简单的方法是有一个方法，用于每当您想要取消键盘时，看起来像这样：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2402271|-(void)dismissKeyboard+{
++++[firstField+becomeFirstResponder];
++++[firstField+resignFirstResponder];
}|code-block|syntax|javascript|2402272|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

The easiest way to do this is to have a method for whenever you want to dismiss the keyboard that looks like this:

<pre><code>-(void)dismissKeyboard {
 [firstField becomeFirstResponder];
 [firstField resignFirstResponder];
}
</code></pre>

blocks|key|1518963|text|在我自己的应用程序中，当我有多个文本字段，并且想要让键盘消失而不管是哪个字段调用它时，我只需要编写一个方法，让它们中的每一个都成为resignFirstResponder。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1518964|我假设作为一名程序员，你应该清楚地知道你的视图控制器上有多少文本字段以及如何访问它们，否则它会变得一团糟，你的应用程序看起来也不会很好……:-P|1518965|entityMap^0|1T|K|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|N|8|@]|D|@]|E|$]]]|I|$]]

In my own app when I had more than one text field and would like to make the keyboard go away regardless which of the fields called it, I would just wrote a method and let each and every of them <code>resignFirstResponder</code>.

I assume that as a programmer, you should have the clear knowledge how many text fields are on your view controller and how you can access them, otherwise it'll get messed up and you app won't look good... :-P

I know that this has already been marked as answered, but for those that run into this like I did you can just use the following method on the view that contains the textfields.

<pre><code>- (BOOL)endEditing:(BOOL)force
</code></pre>

<blockquote>
 This method looks at the current view and its subview hierarchy for the text field that is currently the first responder. If it finds one, it asks that text field to resign as first responder. If the force parameter is set to YES, the text field is never even asked; it is forced to resign. <a href="http://developer.apple.com/library/ios/#documentation/uikit/reference/uiview_class/uiview/uiview.html" rel="nofollow noreferrer">UIView Documentation</a>
</blockquote>

<pre><code>[self.view endEditing:YES];
</code></pre>

it will hide keyboard when we click on view.

In summary:
You can call becomeFirstResponder on some other thing that you choose. It could be a UIViewController or a UIView. I had a similar problem before, I needed to make my keyboard go away when I was pushing my view controller back to its caller, without knowing which textfield was the first responder. Then, on viewWillAppear of my view controller which I was returning back, I called [self becomeFirstResponder] and the keyboard of the pushed view was gone. Because this made whichever text field was it loose being the first responder

blocks|key|1516351|text|在以下代码的帮助下，您可以在不引用任何UITextfield+/+UITextView的情况下关闭键盘：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1516352|[[[UIApplication+sharedApplication]+keyWindow]+endEditing:YES];|code-block|syntax|javascript|1516353|这将在没有引用的情况下全局关闭键盘。|1516354|希望这能对你有所帮助。|1516355|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

You can dismiss the keyboard without any reference to UITextfield / UITextView with help of below code:

<pre><code>[[[UIApplication sharedApplication] keyWindow] endEditing:YES];
</code></pre>

this will dismiss the keyboard globally without the reference.

hope this will help you.

Is there a way to do a general <code>resignFirstResponder</code> to hide the keyboard regardless of what textfield/view/etc calls it?

Reason is I have a lot of textfields on my view and don't want to have to <code>resignFirstResponder</code> for all textfields to hide the keyboard. Just want a general 

<code>[self resignFirstResponder]</code>.

Any ideas?

Thanks in advance

有没有一种方法可以做一个通用的resignFirstResponder来隐藏键盘，而不管文本字段/视图/等等是什么名称？原因是我的视图上有很多文本字段，不想让所有的文本字段都使用resignFirstResponder来隐藏键盘。我只想要一个将军[self resignFirstResponder]。有什么想法吗？提前...
