Question

我有三个文本字段。这三个字段是在UITableViewCell中获取的，这个单元格被传递到UITableViewController中。在这个tableviewcontroller中，我为每个自定义单元格文本字段选择了日期选择器。它显示了日期选择器。

我的问题是，虽然更改选择器值不会放在文本上...值会显示在控制台中，但它不会显示在表格视图文本字段中...

Answer 1

检查你是否有正确的东西

    - (void)datePickerValueChanged:(UIDatePicker*)datePicker
    {
       NSIndexPath *indexPath = selectedIndexPath;

           [tableData replaceObjectAtIndex:indexPath.row withObject:datePicker.date];

           [self.tableView reloadData];
    }

让我更详细地了解您的问题

您是否尝试在更改某个值后重新加载表格视图？

[myTableview reloadData];

尝试解决这个问题

 NSString *datePicValue;
- (void)viewpic:(DatePicker *)viewpic didSelectValue:(NSString *)value
{

      datePicValue=[[NSString alloc] initWithString:value];


}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
     WorkOrderObj *obj=[app.bookdJobData objectAtIndex:indexPath.row];
     NSLog(@"workObj Count:%d",[app.bookdJobData count]);
     static NSString *CustomCellIdentifier = @"ContactLogCC";
     ContactLogCC *cell = (ContactLogCC *)[tableView dequeueReusableCellWithIdentifier: CustomCellIdentifier];

    if (cell == nil) 
   { 
        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"ContactLogCC" owner:self options:nil];
       {
           for (id oneObject in nib) if ([oneObject isKindOfClass:[ContactLogCC class]])
               cell = (ContactLogCC *)oneObject;
       }

      cell.lblDate.text=datePicValue;

  }
 return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
  {

      self.ViewDate = [[[DatePicker alloc] 
                  initWithNibName:@"DatePicker" 
                  bundle:[NSBundle mainBundle]] autorelease];
      ViewDate.contentSizeForViewInPopover=CGSizeMake(ViewDate.view.frame.size.width,      ViewDate.view.frame.size.height);

      ViewDate.delegate = self;
      self.popoverController = [[[UIPopoverController alloc] initWithContentViewController:ViewDate] autorelease];
      [self.popoverController presentPopoverFromRect:CGRectMake(400,140,          ViewDate.view.frame.size.width, ViewDate.view.frame.size.height)
                                        inView:tblVw
                      permittedArrowDirections:UIPopoverArrowDirectionLeft
                                      animated:YES];

}

表重新加载是程序，另一个是下面的

<。>在.h文件中使用一个textField对象，如

    UITextField *txt_current;

in .m

    - (void)textFieldDidBeginEditing:(UITextField *)textField;
    {
       txt_current  = textField;
    }
    -(void) pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component{
    txt_current.text = @"selected value"
    }

我们如何将DatePicker值传递到UITextField中的UITableView？
