UITableView的cell动态高度的方法

常规办法：

- (CGFloat)tableView:(UITableView *)tableViewheightForRowAtIndexPath:(NSIndexPath *)indexPath

{

　　if(0 == [indexPath row])

　　{

　　　　return 10;

　　}

　　

    if(1 == [indexPath row])

　　{

　　　　return 30;

　　}

}

然后：

- (CGFloat)tableView:(UITableView *)tableViewheightForRowAtIndexPath:(NSIndexPath *)indexPath
｛
          if( 0 == [indexPath row])
        {
          // xxxx cell.contoneview = [[UIView allco] initwhithframe:CGRectMake(0, 0, 80, 10)];
        }    
   if( 1 == [indexPath row])
        {
          //ooo cell.contoneview = [[UIView allco] initwhithframe:CGRectMake(0, 0, 80, 30)];
        }    
}

比较好的做法：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
 
    static NSString *CellIdentifier = @"Cell";
 
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
    UILabel *label = (UILabel *)[cell viewWithTag:1];
   
    CGRect cellFrame = [cell frame];
    cellFrame.origin = CGPointMake(0, 0);
 
    
    CGRect rect = CGRectInset(cellFrame, 100, 40);
    label.frame = rect;
    
    if (label.frame.size.height > 30)
 {
        cellFrame.size.height = 150 + label.frame.size.height -30;
    }
    else 
   {
        cellFrame.size.height = 150;
    }
    [cell setFrame:cellFrame];
        
    }

 
    return cell;
}
 
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [self tableView:tableView cellForRowAtIndexPath:indexPath];
    return cell.frame.size.height;
}
