关闭UITextField上的键盘 [英] Close the keyboard on UITextField

问题描述

我是为iOS设备开发的新手。我在InterfaceBuilder上插入了一个UITextField，我分配了代码：

I'm a newbie developing for iOS devices. I inserted an UITextField on InterfaceBuilder, and I assigned with the code:

@interface ComposeViewController : UIViewController {
 id <ComposeViewControllerDelegate> delegate;
 IBOutlet UITextField *notificationTitle;
}

当用户按下返回键时，如何关闭键盘？

How I could allow to close the keyboard when the user press the "Return" key?

推荐答案

将UITextField的Delegate设置为ViewController，在File的Owner和UITextField之间添加一个引用插座，然后实现此方法：

Set the Delegate of the UITextField to your ViewController, add a referencing outlet between the File's Owner and the UITextField, then implement this method:

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
   if (textField == yourTextField) {
       [textField resignFirstResponder];
   }
   return NO;
}
