行の高さのサイズを動的に設定したいコードは次のとおりです。行ごとに動的に高くするのに最適ですが、2行のセクションが必要で、コードが機能しません
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath;
{
NSString *text = [items objectAtIndex:[indexPath row]];
CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 20000.0f);
CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
CGFloat height = MAX(size.height, 44.0f);
return height + (CELL_CONTENT_MARGIN * 5);
}
- (UITableViewCell *)tableView:(UITableView *)tv cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell;
UILabel *label = nil;
cell = [tv dequeueReusableCellWithIdentifier:@"Cell"];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"Cell"] autorelease];
label = [[UILabel alloc] initWithFrame:CGRectZero];
[label setLineBreakMode:UILineBreakModeWordWrap];
[label setMinimumFontSize:FONT_SIZE];
[label setNumberOfLines:0];
[label setFont:[UIFont systemFontOfSize:FONT_SIZE]];
[label setTag:1];
label.textColor = [UIColor darkGrayColor];
[[cell contentView] addSubview:label];
}
NSString *text = [items objectAtIndex:[indexPath row]];
CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 20000.0f);
CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
if (!label)
label = (UILabel*)[cell viewWithTag:1];
[label setText:text];
[label setFrame:CGRectMake(CELL_CONTENT_MARGIN-5, CELL_CONTENT_MARGIN+20, CELL_CONTENT_WIDTH - ((CELL_CONTENT_MARGIN * 2)+6), MAX(size.height, 44.0f))];
今、私はこのコードを置き換えました
NSString *text = [items objectAtIndex:[indexPath row]];
これによって
NSString *text = [items objectAtIndex:([indexPath section]*2 + [indexPath row])];
すべての行のフレーム サイズ行 0 & 1 を取得します
