Question

我有一个文字字段说jobTextFiels，其inputView是UIPickerView，inputAccessoryView是UIToolBar。单击完成按钮（在工具栏中），如果从选择器中选择的行包含文本＆＃34;其他＆＃34;，则会出现一个样式为plainTextStyle的警报。我的问题是，如果用户选择其他人＆＃39;从选择器中单击警报上的添加按钮，然后为jobTextField显示正常键盘。我已经尝试过各种各样的事情，即尽可能地辞去这个文本域，但对我来说没有任何作用。

-(void)viewDidLoad
{
    pickerView = [[UIPickerView alloc] init];
    pickerView.delegate = self;
    pickerView.dataSource = self;
    pickerView.showsSelectionIndicator = YES;
    pickerView.backgroundColor=[UIColor whiteColor];
    _jobTypeTxtFld.inputView = pickerView;
    _genderTxtFld.inputView = pickerView;

    UIToolbar* numberToolbar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 50)];
    numberToolbar.barStyle = UIBarStyleDefault;
    numberToolbar.items = [NSArray arrayWithObjects:
                           [[UIBarButtonItem alloc]initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:self action:@selector(doneWithNumberPad)],
                           nil];
    [numberToolbar sizeToFit];
    _jobTypeTxtFld.inputAccessoryView = numberToolbar;
    _genderTxtFld.inputAccessoryView = numberToolbar;
}

- (void)doneWithNumberPad{

    if (_jobTypeTxtFld.isFirstResponder) {
        if ([self.jobTypeTxtFld.text isEqualToString:@"Others"])
        {
            [UITextFieldAnimation moveContainerToInitialPositionWithView:self.bgView];
            jobAlert = [[UIAlertView alloc]initWithTitle:@"Please enter your job type" message:nil delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Add",nil];
            jobAlert.alertViewStyle = UIAlertViewStylePlainTextInput;
            [jobAlert show];
        }
        else
        {
            [self.addrssTxtFld becomeFirstResponder];
        }
    }
    //[self.view endEditing:YES];
}

- (void)alertView:(UIAlertView *)alertview clickedButtonAtIndex:(NSInteger)buttonIndex
{
switch (buttonIndex)
    {
        case 0:
        {

        }
            break;

        case 1:
        {
            if (alertview == jobAlert) {
               // [_jobTypeTxtFld resignFirstResponder];
                [[jobAlert textFieldAtIndex:0] resignFirstResponder];
                if ([[jobAlert textFieldAtIndex:0].text isEqualToString:@""])
                {
                    [UITextFieldAnimation getAlertWithTitle:@"Message" andMessage:@"Please enter your job type!"];
                    [[jobAlert textFieldAtIndex:0] resignFirstResponder];
                }
                else
                {
                    self.jobTypeTxtFld.text = [jobAlert textFieldAtIndex:0].text;
                    [[jobAlert textFieldAtIndex:0] resignFirstResponder];
                }
                [_jobTypeTxtFld resignFirstResponder];
            }
        }
            break;

点击完成按钮调用方法regisignFirstResponder。我希望这会对你有所帮助。

使用TextField单击警报时，UIPickerView将更改为普通textField
