我正在尝试UILabel
根据标签中的文本数量来更改 a 的高度。
我可以计算标签所需的尺寸,但是当我尝试设置UILabel
框架时,它并没有改变。
下面是我的代码。即使我将最后一行中的 size.height 替换为 500 之类的东西,UILabel
框架的大小也不会改变
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = @"GameItemCell";
GameItemCell *cell = (GameItemCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"GameItemCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
GameItem* item = [_hunt.gameItems objectAtIndex: indexPath.row];
cell.itemHeaderLabel.text = [NSString stringWithFormat:@"#%d - (%d pts)", indexPath.row+1, item.itemPoints];
UILabel* textLabel = cell.itemTextLabel;
textLabel.text = item.itemText;
textLabel.lineBreakMode = NSLineBreakByWordWrapping;
CGRect frame = cell.itemTextLabel.frame;
CGSize textSize = { frame.size.width, 20000.0f };
CGSize sizeOneLine = [@"one line" sizeWithFont:cell.itemTextLabel.font constrainedToSize:textSize lineBreakMode:NSLineBreakByWordWrapping];
CGSize cellTextSize = [item.itemText sizeWithFont:cell.itemTextLabel.font constrainedToSize:textSize lineBreakMode:NSLineBreakByWordWrapping];
CGSize sizeOneLineSpacing = CGSizeMake(sizeOneLine.width, sizeOneLine.height + 3);
NSInteger lines = cellTextSize.height / sizeOneLine.height;
CGSize size = CGSizeMake(frame.size.width, lines * sizeOneLineSpacing.height);
textLabel.frame = CGRectMake(frame.origin.x, frame.origin.y, size.width, size.height);
return cell;
}
