ios - 如果要弹出操作表，则隐藏键盘

Question

我有一个应用程序，其中有 2 个文本字段。现在我的问题是，假设第一个用户点击普通文本字段。这将弹出键盘。然后，他没有选择“完成”按钮，而是点击了日期字段。这将弹出操作表(无需关闭键盘)。隐藏操作表后，用户必须点击其他文本字段并单击键盘的返回键。

如果要弹出操作表，我想隐藏键盘吗？

我的代码如下

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


    if([textField isEqual:txtdob])
    {

        [textField resignFirstResponder];


        actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:nil cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil];
        [actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];
       // txtdob.inputView=actionSheet;
        CGRect pickerFrame = CGRectMake(0, 40, 0, 0);

        datepicker=[[UIDatePicker alloc] initWithFrame:pickerFrame];
        datepicker.datePickerMode = UIDatePickerModeDate;
        //[datepicker setMinimumDate:minDate];
        [datepicker addTarget:self action:@selector(changeDateInLabel:) forControlEvents:UIControlEventValueChanged];

        [actionSheet addSubview:datepicker];
        [datepicker release];

        UISegmentedControl *closeButton = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObject:@"Done"]];
        closeButton.momentary = YES; 
        closeButton.frame = CGRectMake(260, 7.0f, 50.0f, 30.0f);
        closeButton.segmentedControlStyle = UISegmentedControlStyleBar;
        closeButton.tintColor = [UIColor blueColor];
        [closeButton addTarget:self action:@selector(dismissActionSheet) forControlEvents:UIControlEventValueChanged];
        [actionSheet addSubview:closeButton];
        [closeButton release];

        [actionSheet showInView:self.view];

        [actionSheet setBounds:CGRectMake(0, 0, 320, 485)];

    }
}

在你的 ViewController 中调用它

[self.view endEditing:NO];
