Question

UITableViewCellStyleSubtitle的tableView单元格将截断文本。此外，如果使用删除幻灯片，则多行的常规UITableCell将截断文本。

但是，当删除幻灯片进入时，多行的UITableViewCellStyleSubtitle单元格不会截断文本。而是延伸到单元格的边界之外。我能解决这个问题吗？这是我的一些代码...

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:@"SwitchCell"];

if (cell==nil){
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"cellType"] autorelease];
    // set the labels to the appropriate text for this row
    cell.textLabel.text = [(Group*)[composeData objectInChosenGroupsListAtIndex:indexPath.row]groupName];
    cell.textLabel.lineBreakMode=UILineBreakModeTailTruncation;
    cell.textLabel.numberOfLines = 0;

    if ([(Group*)[composeData objectInChosenGroupsListAtIndex:indexPath.row]isDynamic]){
         cell.detailTextLabel.text = NSLocalizedString(@"dynamic", @"dynamic");
    }
    else {
        //get and set the group size
        int groupSize = [(Group*)[composeData objectInChosenGroupsListAtIndex:indexPath.row]groupSize];

        if (groupSize == 1)
            cell.detailTextLabel.text = NSLocalizedString(@"1Contact", @"1 contact");
        else
            cell.detailTextLabel.text = [NSString stringWithFormat:NSLocalizedString(@"%dContacts", @"%d contacts"), groupSize];
    }     
}

return cell;
}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{

UITableViewCell *cell = (UITableViewCell *)[self tableView: tableView cellForRowAtIndexPath: indexPath];

CGRect frame = [UIScreen mainScreen].bounds;
CGFloat width = frame.size.width;

int section = indexPath.section;

NSString *title_string = cell.textLabel.text;
NSString *detail_string = cell.detailTextLabel.text;

CGSize title_size = {0, 0};
CGSize detail_size = {0, 0};

if (title_string && [title_string isEqualToString:@""] == NO ) {
    title_size = [title_string sizeWithFont:[UIFont systemFontOfSize:22.0]
                          constrainedToSize:CGSizeMake(width, 4000)
                              lineBreakMode:cell.textLabel.lineBreakMode];
}

if (detail_string && [title_string isEqualToString:@""] == NO ) {
    detail_size = [detail_string sizeWithFont:[UIFont systemFontOfSize:18.0]
                            constrainedToSize:CGSizeMake(width, 4000)
                                lineBreakMode:cell.detailTextLabel.lineBreakMode];
}

CGFloat title_height = title_size.height;
CGFloat detail_height = detail_size.height;

CGFloat content_size = title_height + detail_height;

CGFloat height;

switch ( section ) {

    case 0:
        height = content_size;
        break;

        //Just in case  
    default:
        height = 44.0;
        break;

}

return height;

}

Answer 1

尝试设置标签大小，即MAX宽度，如下所示：

cell.textLabel.frame.size.width = someWidth;

cell.detailTextLabel.frame.size.width = someWidth;

Answer 2

这很难解决！问题是如果numberOfLines设置为0，它将始终拉伸文本。因此，我需要计算numberOfLines，并为每个单元格设置它。

cell.textLabel.numberOfLines = textLabelheight/textLabelFontSize;

文本在删除幻灯片上的单元格边界外延伸
