Is it possible to disable floating headers in UITableView with UITableViewStylePlain

Question

I m using a UITableView to layout content  pages   I m using the headers of the table view to layout certain images etc  and I d prefer it if they didn t float but stayed static as they do when the style is set to UITableViewStyleGrouped   Other then using UITableViewStyleGrouped  is there a way to do this  I d like to avoid using grouped as it adds a margin down all my cells and requires disabling of the background view for each of the cells  I d like full control of my layout  Ideally they d be a  UITableViewStyleBareBones   but I didn t see that option in the docs     Many thanks

There is another tricky way  The main idea is to double the section number  and first one only shows the headerView while the second one shows the real cells   -  NSInteger numberOfSectionsInTableView  UITableView   tableView       return sectionCount   2    -  NSInteger tableView  UITableView   tableView numberOfRowsInSection  NSInteger section       if  section 2    0            return 0            return  rowCount      What need to do then is to implement the headerInSection delegates   -  UIView   tableView  UITableView   tableView viewForHeaderInSection  NSInteger section       if  section 2    0              return headerview            return nil     -  CGFloat tableView  UITableView   tableView heightForHeaderInSection  NSInteger section       if  section 2    0              return headerheight            return 0      This approach also has little impact on your datasources   -  UITableViewCell   tableView  UITableView   tableView cellForRowAtIndexPath  NSIndexPath   indexPath       int real section    int indexPath section   2        your code     Comparing with other approaches  this way is safe while not changing the frame or contentInsets of the tableview  Hope this may help

You should be able to fake this by using a custom cell to do your header rows  These will then scroll like any other cell in the table view   You just need to add some logic in your cellForRowAtIndexPath to return the right cell type when it is a header row    You ll probably have to manage your sections yourself though  i e  have everything in one section and fake the headers   You could also try returning a hidden view for the header view  but I don t know if that will work

A variation on  samvermette s solution       Allows for disabling scrolling headers in plain-styled tableviews extension UITableView        static let shouldScrollSectionHeadersDummyViewHeight   CGFloat 40       var shouldScrollSectionHeaders  Bool           set               if newValue                   tableHeaderView   UIView frame  CGRect x  0  y  0  width  bounds size width  height  UITableView shouldScrollSectionHeadersDummyViewHeight                   contentInset   UIEdgeInsets top  -UITableView shouldScrollSectionHeadersDummyViewHeight  left  0  bottom  0  right  0                else                   tableHeaderView   nil                 contentInset    zero                                  get               return tableHeaderView    nil  amp  amp  contentInset top    UITableView shouldScrollSectionHeadersDummyViewHeight

Change your TableView Style   self tableview     UITableView alloc  initwithFrame frame style UITableViewStyleGrouped     As per apple documentation for UITableView      UITableViewStylePlain- A plain table view  Any section headers or   footers are displayed as inline separators and float when the table   view is scrolled       UITableViewStyleGrouped- A table view whose sections present distinct   groups of rows  The section headers and footers do not float

Another way to do it is to make an empty section right before the one you want the header on and put your header on that section  Because the section is empty the header will scroll immediately

User · Answer

you can easily achieve this by implementing the viewForHeaderInSection method in the tableview delegate class  this method expects a UIView as return object  which is your header view   i have done this same thing in my code

Ok  i know it is late but i had to do it  I have spent 10 hours by now searching for a working solution but did not find a complete answer  Did found some hints but difficult for starters to understand  So i had to put in my 2 cents and complete the answer   As it has been suggested in the few of the answers the only working solution that i was able to implement is by inserting normal cells in the table view and handle them as Section Headers  but the better way to achieve it is by inserting these cells at row 0 of every section  This way we can handle these custom non-floating headers very easily   So  the steps are    Implement UITableView with style UITableViewStylePlain   - void  loadView        super loadView        UITableView  tblView    UITableView alloc  initWithFrame CGRectMake 0  frame origin y  frame size width  frame size height-44-61-frame origin y  style UITableViewStylePlain       tblView delegate self      tblView dataSource self      tblView tag 2      tblView backgroundColor  UIColor clearColor       tblView separatorStyle   UITableViewCellSeparatorStyleNone     Implement titleForHeaderInSection as usual   you can get this value by using your own logic  but I prefer to use standard delegates     -  NSString   tableView   UITableView   tableView titleForHeaderInSection  NSInteger section       NSString  headerTitle    sectionArray objectAtIndex section       return headerTitle     Immplement numberOfSectionsInTableView as usual  -  NSInteger numberOfSectionsInTableView  UITableView   tableView        int sectionCount    sectionArray count       return sectionCount     Implement  numberOfRowsInSection as usual   -  NSInteger tableView  UITableView   tableView numberOfRowsInSection  NSInteger section        int rowCount     cellArray objectAtIndex section  count       return rowCount  1     1 for the extra row which we will fake for the Section Header    Return 0 0f in heightForHeaderInSection   -  CGFloat tableView  UITableView   tableView heightForHeaderInSection  NSInteger section       return 0 0f     DO NOT implement viewForHeaderInSection  Remove the method completely instead of returning nil  In heightForRowAtIndexPath  Check if indexpath row    0  and return the desired cell height for the section header  else return the height of the cell   -  CGFloat tableView  UITableView   tableView heightForRowAtIndexPath  NSIndexPath   indexPath       if indexPath row    0                return 80    Height for the section header           else               return 70    Height for the normal cell          Now in cellForRowAtIndexPath  check if indexpath row    0  and implement the cell as you want the section header to be and set the selection style to none  ELSE implement the cell as you want the normal cell to be   -  UITableViewCell   tableView  UITableView   tableView cellForRowAtIndexPath  NSIndexPath   indexPath       if  indexPath row    0                UITableViewCell  cell    tableView dequeueReusableCellWithIdentifier   SectionCell            if  cell    nil                        cell      UITableViewCell alloc  initWithStyle UITableViewCellStyleDefault reuseIdentifier   SectionCell   autorelease               cell selectionStyle   UITableViewCellSelectionStyleNone    So that the section header does not appear selected              cell backgroundView     UIImageView alloc  initWithImage  UIImage imageNamed   SectionHeaderBackground                        cell textLabel text    tableView dataSource tableView tableView titleForHeaderInSection indexPath section            return cell            else               UITableViewCell  cell    tableView dequeueReusableCellWithIdentifier   Cell             if  cell    nil                         cell      UITableViewCell alloc  initWithStyle UITableViewCellStyleDefault reuseIdentifier   Cell   autorelease               cell selectionStyle   UITableViewCellSelectionStyleGray    So that the normal cell looks selected              cell backgroundView     UIImageView alloc  initWithImage  UIImage imageNamed   CellBackground   autorelease               cell selectedBackgroundView    UIImageView alloc  initWithImage  UIImage imageNamed   SelectedCellBackground    autorelease                      cell textLabel text     cellArray objectAtIndex indexPath section  objectAtIndex indexPath row -1     row -1 to compensate for the extra header row          return cell           Now implement willSelectRowAtIndexPath and return nil if indexpath row    0  This will care that didSelectRowAtIndexPath never gets fired for the Section header row   -  NSIndexPath   tableView  UITableView   tableView willSelectRowAtIndexPath  NSIndexPath   indexPath       if  indexPath row    0                return nil             return indexPath     And finally in didSelectRowAtIndexPath  check if indexpath row    0  and proceed   -  void tableView  UITableView   tableView didSelectRowAtIndexPath  NSIndexPath   indexPath       if  indexPath row    0                int row   indexPath row -1    Now use  row  in place of indexPath row            Do what ever you want the selection to perform            With this you are done  You now have a perfectly scrolling  non-floating section header

The interesting thing about UITableViewStyleGrouped is that the tableView adds the style to the cells and not to the TableView   The style is added as backgroundView to the cells as a class called UIGroupTableViewCellBackground which handles drawing different background according to the position of the cell in the section   So a very simple solution will be to use UITableViewStyleGrouped  set the backgroundColor of the table to clearColor  and simply replace the backgroundView of the cell in cellForRow   cell backgroundView      UIView alloc  initWithFrame cell bounds  autorelease

Maybe you could use scrollViewDidScroll on the tableView and change the contentInset based on the current visible header   It seems to work for my use case   extension ViewController   UIScrollViewDelegate       func scrollViewDidScroll   scrollView  UIScrollView            guard   let tableView   scrollView as  UITableView              let visible   tableView indexPathsForVisibleRows              let first   visible first else               return                    let headerHeight   tableView rectForHeader inSection  first section  size height         let offset    max min 0  -tableView contentOffset y   -headerHeight          self tableView contentInset   UIEdgeInsetsMake offset  0  -offset  0

Although this may not solve your problem  it did for me when I wanted to do a similar thing  Instead of setting the header I used the footer of the section above  What saved me was that this section was small and static in nature  so it never scrolled below the bottom of the view

WARNING  this solution implements a reserved API method  This could prevent the app from being approved by Apple for distribution on the AppStore   I ve described the private methods that turns of section headers floating in my blog  Basically  you just need to subclass UITableView and return NO in two of its methods   -  BOOL allowsHeaderViewsToFloat  -  BOOL allowsFooterViewsToFloat

This can be achieved by assigning the header view manually in the UITableViewController s viewDidLoad method instead of using the delegate s viewForHeaderInSection and heightForHeaderInSection   For example in your subclass of UITableViewController  you can do something like this   -  void viewDidLoad        super viewDidLoad        UILabel  headerView     UILabel alloc  initWithFrame CGRectMake 0  0  0  40         headerView setBackgroundColor  UIColor magentaColor         headerView setTextAlignment NSTextAlignmentCenter        headerView setText   Hello World          self tableView  setTableHeaderView headerView       The header view will then disappear when the user scrolls   I don t know why this works like this  but it seems to achieve what you re looking to do

I have another even simpler solution  to be used without autolayout and with everything done through the XIB    1  Put your header in the tableview by drag and dropping it directly on the tableview   2  In the Size Inspector of the newly made header  just change its autosizing   you should only leave the top  left and right anchors  plus the fill horizontally     That should do the trick

To remove the floating section header sections completely  you can do this   -  UIView    tableView  UITableView   tableView viewForHeaderInSection  NSInteger section       return   UIView alloc  init       return nil doesn t work   To disable floating but still show section headers you can provide a custom view with its own behaviours

While thinking how to approach this problem  I remembered a very important detail about UITableViewStyleGrouped  The way UITableView implements the grouped style  the rounded borders around the cells  is by adding a custom backgroundView to the UITableViewCells  and not to the UITableView  Each cell is added a backgroundView according to its position in the section  upper rows get the upper part of the section border  middle ones get the side border and the bottom one gets     well  the bottom part   So  if we just want a plain style  and we don   t have a custom backgroundView for our cells  which is the case in 90  of the times   then all we need to do is use UITableViewStyleGrouped  and remove the custom background  This can be done by following those two steps   Change our tableView style to UITableViewStyleGrouped Add the following line to cellForRow  just before we return the cell   cell backgroundView    UIView alloc  initWithFrame cell bounds  autorelease    And that   s it  The tableView style will become exactly like UITableViewStylePlain  except for the floating headers   Hope this helps

Ignore XAK   Do not explore any private methods if you want your app to have the chance of being accepted by apple   This is easiest if you are using Interface Builder  You would add a UIView at the top of the view  where the images will go   then add your tableview below that   IB should size it accordingly  that is  the top of the tableview touches the bottom of the UIView you ve just added and it s height covers the rest of the screen   The thinking here is that if that UIView is not actually part of the table view  it will not scroll with the tableview  i e  ignore the tableview header   If you re not using interface builder  it s a little more complicated because you ve got to get the positioning and height correct for the tableview
