Question

此代码无法正常工作，并且第一次不会加载完整数据，并且一旦滚动就可以正常工作。

#define ROW_HEIGHT 110

// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSLog( @"Setting table text." );

static NSString *CellIdentifier = @"Transaction";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
    [cell addSubview:[[UILabel alloc] initWithFrame:CGRectMake(40.0, 0.0, 280.0, ROW_HEIGHT - 1)]];
}

NSUInteger row = [indexPath row];

NSLog( @"Table cell text: %@", [[transactionHistory objectAtIndex:row] description] );

UILabel *labelText = [[cell subviews] lastObject];
labelText.text = [[transactionHistory objectAtIndex:row] description];
labelText.font = [UIFont systemFontOfSize:14];
labelText.lineBreakMode = UILineBreakModeWordWrap;
labelText.numberOfLines = 5;    

return cell;
}


- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
return ROW_HEIGHT;
}

可能出现什么问题？

替换此行

    [cell addSubview:[[UILabel alloc] initWithFrame:CGRectMake(40.0, 0.0, 280.0, ROW_HEIGHT - 1)]];

要

   [cell.contentView addSubview:[[UILabel alloc] initWithFrame:CGRectMake(40.0, 0.0, 280.0, ROW_HEIGHT - 1)]];
