The view has an endEditing: method you can use. The docs say

视图有一个endEditing:您可以使用的方法。文档说

Causes the view (or one of its embedded text fields) to resign the first responder status.

导致视图(或其中一个嵌入的文本字段)重新签署第一个响应者状态。

In your view controller you can just call:

在视图控制器中,您只需调用:

[[self view] endEditing:YES];

Its very easy now. You can follow different approach depending on your use cases. In my case I had multiple textfields in UITableViewController. What I did is this :

现在非常容易。您可以根据您的使用情况采用不同的方法。在我的例子中,我在UITableViewController中有多个文本字段。我做的是这样的:

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];

    [self.view endEditing:YES];
}

Best answer is:

最佳答案是:

1. Added UITextFieldDelegate protocol to your viewcontroller @interface ViewController : UIViewController

将UITextFieldDelegate协议添加到viewcontroller @interface ViewController:UIViewController

2. In your xib, select the textField, in your Ulitlites section in the right side pane of XCode in the subsection of "Connections Inspector", link the textField's delegate with the .xib's "File's Owner".

在你的xib中,选择textField,在“Connections Inspector”子部分的XCode右侧窗格的Ulitlites部分中,将textField的委托链接到.xib的“文件所有者”。

3. In your Viewcontroller implementation, include the follwing

在Viewcontroller实现中,包括以下内容

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