iphone – UITextField中的UIDatePicker在UITableView实时更新中

这些是我的目标：

>在UITableViewCell中为UItextField设置UIDatePickerView.

到目前为止,我已经完成了所有这些,我可以看到选择器工作正常.每当我更改选择器值时,我都会使用NSLog来显示当前值,并且每次更改都能正常工作.

这就是我要的：
**每当我更改pickervalue时,我都需要在UITextField中自动更改该值(在UITableViewCell中)**

这是我的CellForRowIndexPath代码：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] autorelease];
    UITextField *textField = [[UITextField alloc]initWithFrame:CGRectMake(110,10,185,30)];
    textField.clearsOnBeginEditing = YES;
    textField.textAlignment = UITextAlignmentRight;

    [cell.contentView addSubview:textField];
     UIDatePicker *datePicker = [[UIDatePicker alloc] init];
        datePicker.datePickerMode = UIDatePickerModeDate;
        [datePicker addTarget:self action:@selector(datePickerValueChangedd:) forControlEvents:UIControlEventValueChanged];
        datePicker.tag = indexPath.row;
        textField.inputView = datePicker;

        NSDateFormatter *df = [[NSDateFormatter alloc] init];
        df.dateStyle = NSDateFormatterMediumStyle;
        NSString *local;
        local = [self datePickerValueChangedd: datePicker];  
        NSLog(@"%@",local); //DISPLAYS OUTPUT ONCE
        textField.text =local;
        [datePicker reloadInputViews];
        [datePicker release];




// Configure the cell...

NSInteger row = [indexPath row];
cell.textLabel.text = [doseInfoDetailsArray objectAtIndex:row];

return cell;
 }

我也在下面发布其他代码.

- (NSString *)datePickerValueChangedd:(UIDatePicker*) datePicker{
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(100,50,68,68)];
NSDateFormatter *df = [[NSDateFormatter alloc] init];
df.dateStyle = NSDateFormatterMediumStyle;
label.text = [NSString stringWithFormat:@"%@",[df stringFromDate:datePicker.date]];

NSLog(@"%@",label.text); // DISPLAYS OUTPUT WHENEVER PICKER IS MOVED
doseInfoDetailsTable.reloadData;
return (label.text);
//[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(t) name:TestNotification object:label];
[df release];

}

输出正确显示.但我还需要在UITextField中进行更改.
