Question

在应用委托窗口中添加了subview，textfield位于subview，startDateTxtFld将打开日期选择器，但日期选择器仍在键盘后面。键盘不会隐藏在resignFirstResponder或self.view eneEditing设置为true。

-(void)textFieldDidBeginEditing:(UITextField *)textField
{

    if (textField == startDateTxtFld )
    {
        startDateSelected =YES;
        endDateSelected = NO;
//        [referenceNmbrTxtFld resignFirstResponder];
     //   [startDateTxtFld becomeFirstResponder];
        //textField.inputView=datePicker;
       // [self.view endEditing:YES];
       // [[UIApplication sharedApplication] sendAction:@selector(resignFirstResponder) to:nil from:nil forEvent:nil];
//       [APP_DELEGATE.window resignFirstResponder];
        [[[UIApplication sharedApplication] keyWindow] endEditing:YES];
        [UIView animateWithDuration:0.5 animations:^
        {
            [startDateTxtFld resignFirstResponder];
            _bottomGap4DatePicker.constant=0;
            datePicker.backgroundColor=[UIColor whiteColor];
           // [_subVw4DtPkr becomeFirstResponder];
        }];
       [self.navigationController.view endEditing:YES];
    }
    else if (textField == endDateTxtFld)
    {
        startDateSelected =NO;
        endDateSelected = YES;
       // [self.view endEditing:YES];
//        [referenceNmbrTxtFld resignFirstResponder];
       // [endDateTxtFld becomeFirstResponder];
      //  textField.inputView=datePicker;
      //  [[UIApplication sharedApplication] sendAction:@selector(resignFirstResponder) to:nil from:nil forEvent:nil];
//        [APP_DELEGATE.window resignFirstResponder];
        [[[UIApplication sharedApplication] keyWindow] endEditing:YES];
        [UIView animateWithDuration:0.5 animations:^
         {
            // [endDateTxtFld resignFirstResponder];
             _bottomGap4DatePicker.constant=0;
             datePicker.backgroundColor=[UIColor whiteColor];
             //[_subVw4DtPkr becomeFirstResponder];
         }];
        [self.navigationController.view endEditing:YES];
    }
   else
    {
        [textField becomeFirstResponder];
        _bottomGap4DatePicker.constant=[UIScreen mainScreen].bounds.size.height +_subVw4DtPkr.frame.size.height;
        _popUpVwConstraint.constant=-30;
    }

}

(BOOL)textFieldShouldBeginEditing:(UITextField *)textField { {
    NSLog(@"textFieldDidBeginEditing===%@" , textField.text);
    CGAffineTransform translation = CGAffineTransformIdentity;

    if (textField==vacDate || textField==vacTime) {
        [self.view endEditing:YES];

        [UIView beginAnimations:nil context:nil];
        self.view.transform = translation;
        [UIView commitAnimations];
        myDatePicker.hidden = NO;
        return NO;
    }
    else
    { 
        if (textField==vacType) {
           translation = CGAffineTransformMakeTranslation(0, -60);
        }
        [UIView beginAnimations:nil context:nil];
        self.view.transform = translation;
        [UIView commitAnimations];
        myDatePicker.hidden = YES;
        return YES;
    }
}

Answer 2

隐藏IOS中的键盘：

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    for (UIView * txt in self.view.subviews){
        if ([txt isKindOfClass:[UITextField class]] && [txt isFirstResponder]) {
            [txt resignFirstResponder];
        }
    }
}

OR

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
     [self.view endEditing:YES];    
 }

Answer 3

我尝试了所有解决方案，例如添加

UITextFieldDelegate
tf_edit.returnKeyType = UIReturnKeyDone

- (BOOL)disablesAutomaticKeyboardDismissal
{
     return NO;
}

没有任何帮助。

正在调用textFieldShouldReturn。但键盘没有出现。当我点击DONE按钮时，我看到它会转到其他文本字段。但是没有其他文本领域。因此，我没有将resignFirstResponder应用于我的文本域名，而是应用于textfield，它是textFieldShouldReturn函数的一个参数，并且它有效。我不确定这是否正确。它对我有用。

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

ios键盘没有隐藏在resignfirstresponder上
