如何在没有第一响应者的情况下关闭输入字段

Question

我在一个viewController上，textField是第一个响应者，然后一个视图在一些回调方法上实例化，但键盘仍然在实例化的viewController上打开，我试图通过[self.view endEditing:YES]解除键盘但是它不会工作。

Answer 1

尝试在viewDidDisappear中添加[self.view endEditing：YES]

Answer 2

您可以转到mainStoryBoard，如果它与mainStoryBoard相同，只需检查自动启用返回键上的checkMark，然后返回到您的代码

/// the method where  view is getting instantialte before view get Instantite use this here is sample.

  [self resignKeyBoard];

// goto your code here is uiButton with close icon 

 - (IBAction)closeKeyboardPressed:(id)sender {

 cellTypeButton*btn=(cellTypeButton*)sender;

if(btn.selected){
    btn.selected=false;
    [self resignKeyBoard];
}else{
    btn.selected=true;
    [self resignKeyBoard];
}

}


-(void)resignKeyBoard{

closeKeyBoardBtn.hidden=true;

[PhoneNumTxt resignFirstResponder];
[codeTxt1 resignFirstResponder];
[usernameField resignFirstResponder];
[fullnameField resignFirstResponder];
[statusField resignFirstResponder];
[Utilities animateDownTextField:PhoneNumTxt inView:self.view];
[Utilities animateDownTextField:codeTxt1 inView:self.view];
[Utilities animateDownTextField:usernameField inView:self.view];
[Utilities animateDownTextField:fullnameField inView:self.view];
[Utilities animateDownTextField:statusField inView:self.view];

[self.view endEditing:YES];
}



 //// have a good day :D

Answer 3

使用viewcontroller的默认覆盖功能

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    view.endEditing(true)
}
