Question

我正在尝试了解如何将带有 UISwitch 或其他 Controller 的标签添加到分段 tableView 中的页脚(或页眉)。任何帮助将不胜感激。提前致谢!

好的，在搜索和处理之后，我完成了以下操作:

// Need to refactor so that the label is Public Sharing and Priviate Sharing and the actions work for each switch
- (UIView *) tableView: (UITableView *) tableView
viewForFooterInSection: (NSInteger) section
{
  if (section == 0 || section == 1) {
    CGRect screenRect = [[UIScreen mainScreen] applicationFrame];
    UIView* footerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, screenRect.size.width, 44.0)] autorelease];
    footerView.autoresizesSubviews = YES;
    footerView.autoresizingMask = UIViewAutoresizingFlexibleWidth;
    footerView.userInteractionEnabled = YES;

    footerView.hidden = NO;
    footerView.multipleTouchEnabled = NO;
    footerView.opaque = NO;
    footerView.contentMode = UIViewContentModeScaleToFill;

    // Add the label
    UILabel*    footerLabel = [[UILabel alloc] initWithFrame:CGRectMake(150.0, -5.0, 120.0, 45.0)];
    footerLabel.backgroundColor = [UIColor clearColor];
    footerLabel.opaque = NO;
    footerLabel.text = @"Sharing";
    footerLabel.textColor = [UIColor tableHeaderAndFooterColor];
    footerLabel.highlightedTextColor = [UIColor tableHeaderAndFooterColor];
    footerLabel.font = [UIFont boldSystemFontOfSize:17];
    footerLabel.shadowColor = [UIColor whiteColor];
    footerLabel.shadowOffset = CGSizeMake(0.0, 1.0);
    [footerView addSubview: footerLabel];

    [footerLabel release];  

    // Add the switch
    UISwitch* footerSwitch = [[UISwitch alloc] initWithFrame:CGRectMake(215.0, 5, 80.0, 45.0)];
    [footerView addSubview: footerSwitch];

    // Return the footerView
    return footerView;
  }
  else return nil;
}
// Need to call to pad the footer height otherwise the footer collapses
- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section {
  switch (section) {
    case 0:
    case 1:
      return 40.0;
    default:
      return 0.0;
  }
}

我希望这是正确的，如果这对其他人有帮助，请投赞成票。干杯!
