Question

I have a UIViewController with two UI Components: UITableView and UIDatePicker. My goal is, to create a screen like the ical->add->Start & End.

我将表态代表和日期添加到我的主人档案中。在执行情况档案中,我要显示我的表Cell(如iCalstart & End Screen)中标出的日期。

My .m looks like the following:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

    [datePicker addTarget:self action:@selector(datePickerValueChanged) forControlEvents:UIControlEventValueChanged];

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }

    NSDictionary *dictionary = [listOfItems objectAtIndex:indexPath.section];
    NSMutableArray *dict = [dictionary objectForKey:@"DATA"];


    if(indexPath.row == 1){

        UISwitch *switchSpecifyEnd = [[[UISwitch alloc] initWithFrame:CGRectZero] autorelease];
        cell.accessoryView = switchSpecifyEnd;
        [(UISwitch *)cell.accessoryView setOn:NO];   // Or NO, obviously!
        [(UISwitch *)cell.accessoryView addTarget:self action:@selector(switchSpecifyEnd)
                                 forControlEvents:UIControlEventValueChanged];

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

    }else if(indexPath.row == 3){

        UISwitch *switchOpenEnd = [[[UISwitch alloc] initWithFrame:CGRectZero] autorelease];
        cell.accessoryView = switchOpenEnd;
        [(UISwitch *)cell.accessoryView setOn:NO];   // Or NO, obviously!
        [(UISwitch *)cell.accessoryView addTarget:self action:@selector(switchOpenEnd)
                                 forControlEvents:UIControlEventValueChanged];
        cell.textLabel.text = [dict objectAtIndex:indexPath.row];

    }else{

        cell.textLabel.text = [dict objectAtIndex:indexPath.row];
//        NSLog(@"Update Cell: %@",<but how>);

    }

    return cell;

}

- (void)datePickerValueChanged{
    NSLog(@"Logging: %@", [NSString stringWithFormat:@"%@",datePicker.date]);
}

How can I update my tableCell with the value from the datePicker?

For cell cell you need need need need

假设这是你在选择某一日期时所呼吁的方法。

-(IBAction)setStartTimeMethod
{
    NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];   
    [dateFormat setDateFormat:@"EEE MMM dd, yyyy hh:mm a"];
    self.startTimeString = [dateFormat stringFromDate:[timeStartPicker date]]; 
    [dateFormat release];
    [optionsTableView reloadData];
    }
