如果我们仅在UITableView
单元格中添加文本,则只需要两个委托即可使用(无需添加额外的UILabels
)
1) cellForRowAtIndexPath
2) heightForRowAtIndexPath
这个解决方案为我工作:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.font = [UIFont fontWithName:@"Helvetica" size:16];
cell.textLabel.lineBreakMode = UILineBreakModeWordWrap;
cell.textLabel.numberOfLines = 0;
[cell setSelectionStyle:UITableViewCellSelectionStyleGray];
cell.textLabel.text = [mutArr objectAtIndex:indexPath.section];
NSLog(@"%@",cell.textLabel.text);
cell.accessoryView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"arrow.png" ]];
return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
CGSize labelSize = CGSizeMake(200.0, 20.0);
NSString *strTemp = [mutArr objectAtIndex:indexPath.section];
if ([strTemp length] > 0)
labelSize = [strTemp sizeWithFont: [UIFont boldSystemFontOfSize: 14.0] constrainedToSize: CGSizeMake(labelSize.width, 1000) lineBreakMode: UILineBreakModeWordWrap];
return (labelSize.height + 10);
}
这里的字符串mutArr
是一个可变数组,我从中获取数据。
编辑:-这是我拿的数组。
mutArr= [[NSMutableArray alloc] init];
[mutArr addObject:@"HEMAN"];
[mutArr addObject:@"SUPERMAN"];
[mutArr addObject:@"Is SUPERMAN powerful than HEMAN"];
[mutArr addObject:@"Well, if HEMAN is weaker than SUPERMAN, both are friends and we will never get to know who is more powerful than whom because they will never have a fight among them"];
[mutArr addObject:@"Where are BATMAN and SPIDERMAN"];
