不拉線的UI接法 注意identifier

  
#pragma mark - Table view delegate

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    // Navigation logic may go here. Create and push another view controller.

    switch (indexPath.section) {
    
  case 0:
   [self loadFontSetting];
   return;

 
 }
}
- (void) loadFontSetting
{

    FontSetting *fontSettingpage = [self.storyboard instantiateViewControllerWithIdentifier:@"identifierFontSetting"];
 [self.navigationController pushViewController:fontSettingpage animated: YES];
 
}

鎖定不移動Table

  
- (void)viewDidLoad
{
  self.tableView.scrollEnabled = NO; //關閉不要被scroll影響
}
