【问题描述】:
UITableViewCellStyleSubtitle 的 tableView 单元格会截断文本。 此外,如果使用删除幻灯片,多行的常规 UITableCell 将截断文本。
但是,当删除幻灯片进入时,我的多行 UITableViewCellStyleSubtitle 单元格不会截断文本。相反,它会延伸到单元格的边界之外。我可以解决这个问题吗?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;
}

您要部署到哪个版本?模拟器还是设备?
