问题描述

UIButton是否有办法触发resignFirstResponder?当您在文本字段外点击时，我已将程序设置为在功能中执行此操作，但是我希望当用户单击提交"按钮时键盘消失.

Is there a way for a UIButton to trigger resignFirstResponder?I have my program set to do so in a function when you tap outside of a textfield, but I want the keyboard to go away when the user hits the submit button.

这就是我要使用的UITextFields

This is what I have for the UITextFields

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
 [x1 resignFirstResponder];
 [x2 resignFirstResponder];
 [y1 resignFirstResponder];
 [y2 resignFirstResponder];
}

推荐答案

鉴于您提到的方法的存在，如何:

Given the existence of the method you mention, how about:

- (IBAction)solve:(id)sender {
   [x1 resignFirstResponder];
   [x2 resignFirstResponder];
   [y1 resignFirstResponder];
   [y2 resignFirstResponder];
}
