为什么detailTextLabel不可见?
问题描述：
detailTextLabel不可见(下面的代码).你能告诉我为什么吗?
detailTextLabel is not visible (code below). Can you tell me why?
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell...
NSString *cellValue = [myListArray objectAtIndex:indexPath.row];
cell.textLabel.text = cellValue;
cell.detailTextLabel.text = @"Hello "; // This is not visible
cell.image = [myListArrayImages objectAtIndex:indexPath.row];
return cell;
}
答
对于具有UITableViewCellStyleDefault样式的cells，不会显示detailTextLabel.将init和UITableViewCell替换为UITableViewCellStyleSubtitle，您应该会看到detailTextLabel.
The detailTextLabel is not displayed for cells with the UITableViewCellStyleDefault style. init the UITableViewCell with UITableViewCellStyleSubtitle instead and you should see your detailTextLabel.
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
