objective-c – UITableViewCell不会突出显示

你注意到可能导致这种情况的任何事情吗？

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    int showID = [[[singleton.programs objectAtIndex:indexPath.row]objectForKey:@"id"]intValue];
    //creates the url and loads the list of products
    //NSLog(@"showID: %d",showID);
    URLCreator * productsURL = [[URLCreator alloc] initStandard:@"getProgramProductsForList"];
    [productsURL addParam:@"id" stringValue:[NSString stringWithFormat:@"%d",showID]];
    WebManager *productsWM = [[WebManager alloc]init];
    [productsWM load:[productsURL finalURL] withSelector:@selector(parseProducts) object:[NSNumber numberWithInt:showID]];
}

除了`@ property / @ synthesize @之外,我的自定义单元格目前还没有任何内容,但现在它是.

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
        // Initialization code
    }
    return self;
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
    [super setSelected:selected animated:animated];

    // Configure the view for the selected state
}
