让名字，第一和日期显示在tableview上

Question

我正在开发一个可以存储联系人的应用程序。在表视图中，我有姓氏显示，但希望也有名字和正确的日期。名字保存为名字，日期字段保存为日期。谁能告诉我怎么做这件事?

感谢

 - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{

return [[self.fetchedResultsController sections]count];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
id <NSFetchedResultsSectionInfo> secInfo = [[self.fetchedResultsController sections] objectAtIndex:section];
return [secInfo numberOfObjects];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
Contacts *contacts = [self.fetchedResultsController objectAtIndexPath:indexPath];
cell.textLabel.text = contacts.name;

return cell;
}
-(NSString *) tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
return [[[self.fetchedResultsController sections]objectAtIndex:section]name];
}

这样做。在"cellForRowAtIndexPath"方法中

- (UITableViewCell *)tableView:(UITableView *)atableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UILabel *firstName;
    UILabel *lastName;
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [_tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (!cell)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        firstName =[[UILabel alloc]initWithFrame:CGRectMake(20,0,250,45)] ;
        [cell.contentView addSubview:firstName]; // As your requirement ,adjust the CGRECT. 
        firstName = [UIColor colorWithRed:0.75 green:0.25 blue:0.25 alpha:1.0];
        firstName.backgroundColor = [UIColor clearColor];
        firstName.font = [UIFont systemFontOfSize:[UIFont labelFontSize]];
        lastName =[[UILabel alloc]initWithFrame:CGRectMake(20,35,250,30)] ;
        [cell.contentView addSubview:lastName];
    }
   firstName.text = ['List' objectAtIndex:indexPath.row];
    bottomLabel.text=['List_name' objectAtIndex:indexPath.row];
    return cell;
}

您想在主标签上同时显示姓和名，而在另一个标签上显示日期?还是三种都在同一个标签上?还是用三种不同的建议答案?

这可能是实现请求的最简单方法:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (!cell)//Setting CellStyle to Subtitle, might have to change that in Storyboard as well, by clicking the cell and choose Subtitle as style
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
    Contacts *contacts = [self.fetchedResultsController objectAtIndexPath:indexPath];
    //If I understood right, you knew how to get firstName, and lastName(through .name?), but not both at the same time into the same label?
    //Switch out the following 'contacts.firstName' and 'contacts.name' to fit your needs if it's not right:
    NSString *fullName = [NSString stringWithFormat:@"%@ %@", contacts.firstName, contacts.name];
    cell.textLabel.text = fullName;
    //And put the date on the 'subtitle'(detailTextLabel). Might not work if the date-variable isn't a text, but another type of object, like NSDate etc.
    cell.detailTextLabel.text = contacts.date;
    return cell;
}

如果你的联系人。date-variable是NSDate，看一下这个链接把日期放到NSString中，然后使用cell.detailTextLabel.text = stringFromDate;
