在我的应用程序中,我有一个tableView。我想在表视图的第一行显示明天日期(下一个日期),其余行显示其他数据。如何让第一行为空,然后在其中显示日期。
我的代码是
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
NSUInteger row=[indexPath row ];
if (row==0) {
cell.textLabel.text=@"hi";
}
else{
cell.textLabel.text = [dataFromXml objectAtIndex:indexPath.row];
// cell.detailTextLabel.text = [data objectAtIndex:row];
NSString * detail = [dataFromXml2 objectAtIndex:row]; NSString * dist = [距离objectAtIndex:row];
NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
[numberFormatter setPositiveFormat:@"##0.## km"];
[numberFormatter setNegativeFormat:@"##0.## km"];
NSNumber *number = [NSNumber numberWithDouble:[dist doubleValue]];
NSString *formattedString = [numberFormatter stringFromNumber:number];
NSString *detailSting=[NSString stringWithFormat:@"%@"" - ""%@",detail,formattedString];
cell.detailTextLabel.text = detailSting;
[numberFormatter release];
cell.textLabel.font=[UIFont boldSystemFontOfSize:15];
cell.accessoryType=UITableViewCellAccessoryDetailDisclosureButton;
self.rowImage=[UIImage imageNamed:@"redicon.png"];
cell.imageView.image= self.rowImage;
return cell;
}
}

只需在你的cellForRowAtIndexPath中创建一个特例:
if (indexPath.row == 0) {
/* handle special cell */
}
else {
/* do your usual stuff */
}
要明天的约会,你可以这样做:
NSDate *today = [NSDate date];
NSDate *tomorrow = [today dateByAddingTimeInterval:60*60*24];
然后使用NSDateFormatter转换为字符串。
