uitableview子视图：为什么这个uilabel不可见？ [英] uitableview subview : why this uilabel is not visible?

问题描述

我想在tableview的每个单元格中显示一个显示数字的标签，但只有当我点击一行时（当单元格高位时）才能看到标签

I want to display a label showing a number in each cell of the tableview but the label is only visible when I click on a row (when the cell is highlited)

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"Cell";
    UILabel *label;
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
        cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
        label = [[UILabel alloc] initWithFrame:CGRectMake(200,10, 15, 15)];
        label.tag = 1;
        [cell.contentView addSubview:label];
        [label release];
    }
    else {
        label = (UILabel *)[cell viewWithTag:1];   
    }
    if (indexPath.row == 0) {
        cell.textLabel.text = @"Photos";
        label.text = [NSString stringWithFormat:@"%d",1];
    }
    return cell;
}

推荐答案

我遇到了同样的问题，它是通过在将自定义标签添加为子视图之前设置textlabel的文本来解决的。

I had the same problem and it was solved by setting the text for textlabel BEFORE adding the custom label as a subview.

...
cell.textLabel.text = @"X";
...
[cell.contentView addSubview:label]
