UITableView set to static cells    Is it possible to hide some of the cells programmatically

User · Answer

I got a better way to hide static cells and even sections dynamically without any hacks.

Setting the row height to 0 can hide a row, but that doesn't work if you want to hide an entire section which will hold some spaces even you hide all the rows.

My approach is to build a section array of static cells. Then the table view contents will be driven by the section array.

Here is some sample code:

var tableSections = [[UITableViewCell]]()

private func configTableSections() {
    // seciton A
    tableSections.append([self.cell1InSectionA, self.cell2InSectionA])

    // section B
    if shouldShowSectionB {
        tableSections.append([self.cell1InSectionB, self.cell2InSectionB])
    }

    // section C
    if shouldShowCell1InSectionC {
        tableSections.append([self.cell1InSectionC, self.cell2InSectionC, self.cell3InSectionC])
    } else {
        tableSections.append([self.cell2InSectionC, self.cell3InSectionC])
    }
}

func numberOfSections(in tableView: UITableView) -> Int {
    return tableSections.count
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return tableSections[section].count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    return tableSections[indexPath.section][indexPath.row]
}

This way, you can put all of your configuration code together without having to write the nasty code to calculate number of rows and sections. And of course, no 0 heights anymore.

This code is also very easy maintain. For example, if you want to add/remove more cells or sections.

Similarly, you can create a section header title array and section footer title array to config your section titles dynamically.

In addition to  Saleh Masum solution    If you get auto-layout errors  you can just remove the constraints from the tableViewCell contentView  Swift 3   override func tableView   tableView  UITableView  heightForRowAt indexPath  IndexPath  - gt  CGFloat       let tableViewCell   super tableView tableView  cellForRowAt  indexPath       if tableViewCell isHidden    true               tableViewCell contentView removeConstraints tableViewCell contentView constraints          return 0           else          return super tableView tableView  heightForRowAt  indexPath             This solution depends on the flow of your app  If you want to show hide the cell in the same view controller instance this may not be the best choice  because it removes the constraints

My solution goes into a similar direction as Gareth  though I do some things differently   Here goes   1  Hide the cells  There is no way to directly hide the cells  UITableViewController is the data source which provides the static cells  and currently there is no way to tell it  don t provide cell x   So we have to provide our own data source  which delegates to the UITableViewController in order to get the static cells   Easiest is to subclass UITableViewController  and override all methods which need to behave differently when hiding cells   In the simplest case  single section table  all cells have the same height   this would go like this   -  NSInteger tableView  UITableView   tableView numberOfRowsInSection  NSInteger section           return  super tableView tableView numberOfRowsInSection section  - numberOfCellsHidden     -  UITableViewCell   tableView  UITableView   tableView cellForRowAtIndexPath  NSIndexPath   indexPath          Recalculate indexPath based on hidden cells     indexPath    self offsetIndexPath indexPath        return  super tableView tableView cellForRowAtIndexPath indexPath      -  NSIndexPath  offsetIndexPath  NSIndexPath  indexPath       int offsetSection   indexPath section     Also offset section if you intend to hide whole sections     int numberOfCellsHiddenAbove          Calculate how many cells are hidden above the given indexPath row     int offsetRow   indexPath row   numberOfCellsHiddenAbove       return  NSIndexPath indexPathForRow offsetRow inSection offsetSection       If your table has multiple sections  or the cells have differing heights  you need to override more methods  The same principle applies here  You need to offset indexPath  section and row before delegating to super   Also keep in mind that the indexPath parameter for methods like didSelectRowAtIndexPath  will be different for the same cell  depending on state  i e  the number of cells hidden   So it is probably a good idea to always offset any indexPath parameter and work with these values   2  Animate the change  As Gareth already stated  you get major glitches if you animate changes using reloadSections withRowAnimation  method   I found out that if you call reloadData  immediately afterwards  the animation is much improved  only minor glitches left   The table is displayed correctly after the animation     So what I am doing is   -  void changeState           Change state so cells are hidden unhidden                  Reload all sections     NSIndexSet  reloadSet    NSIndexSet indexSetWithIndexesInRange NSMakeRange 0   self numberOfSectionsInTableView tableView           tableView reloadSections reloadSet withRowAnimation UITableViewRowAnimationAutomatic        tableView reloadData

Solution from k06a  https   github com k06a ABStaticTableViewController  is better because it hides whole section including cells headers and footers  where this solution  https   github com peterpaulis StaticDataTableViewController  hides everything except footer   EDIT  I just found solution if you want to hide footer in StaticDataTableViewController  This is what you need to copy in StaticTableViewController m file   -  NSString   tableView  UITableView   tableView titleForFooterInSection  NSInteger section       if   tableView dataSource tableView tableView numberOfRowsInSection section     0            return nil        else           return  super tableView tableView titleForFooterInSection section            -  CGFloat tableView  UITableView   tableView heightForFooterInSection  NSInteger section        CGFloat height    super tableView tableView heightForFooterInSection section        if  self originalTable    nil            return height             if   self hideSectionsWithHiddenRows            return height             OriginalSection   os   self originalTable sections section       if   os numberOfVissibleRows     0             return 0          return CGFLOAT MIN        else           return height               return 0      return CGFLOAT MIN

The above answers that hide show cells  change rowHeight  or mess with Auto layout constraints didn t work for me because of Auto layout issues  The code became intolerable   For a simple static table  what worked best for me was to    Create an outlet for every cell in the static table Create an array only with the outlets of cells to show Override cellForRowAtIndexPath to return the cell from the array Override numberOfRowsInSection to return the count of the array Implement a method to determine what cells need to be in that array  and call that method whenever needed  and then reloadData    Here is an example from my table view controller    IBOutlet weak var titleCell  UITableViewCell   IBOutlet weak var nagCell  UITableViewCell   IBOutlet weak var categoryCell  UITableViewCell   var cellsToShow   UITableViewCell        override func viewDidLoad         super viewDidLoad       determinCellsToShow      func determinCellsToShow         if detail  duration type    nil           cellsToShow    titleCell  nagCell  categoryCell            else           cellsToShow    titleCell   categoryCell           override func tableView tableView  UITableView  cellForRowAtIndexPath indexPath  NSIndexPath  - gt  UITableViewCell       return cellsToShow indexPath row     override func tableView tableView  UITableView  numberOfRowsInSection section  Int  - gt  Int       return cellsToShow count

Turns out  you can hide and show cells in a static UITableView - and with animation  And it is not that hard to accomplish   Demo project  Demo project video  The gist    Use tableView heightForRowAtIndexPath  to specify cell heights dynamically based on some state  When the state changes animate cells showing hiding by calling tableView beginUpdates   tableView endUpdates   Do not call tableView cellForRowAtIndexPath  inside tableView heightForRowAtIndexPath   Use cached indexPaths to differentiate the cells  Do not hide cells  Set  Clip Subviews  property in Xcode instead  Use Custom cells  not Plain etc  to get a nice hiding animation  Also  handle Auto Layout correctly for the case when cell height    0    More info in my blog  Russian language

To hide static cells in UITable    Add this method    In your UITableView controller delegate class   Objective-C   -  CGFloat tableView  UITableView   tableView heightForRowAtIndexPath  NSIndexPath   indexPath       UITableViewCell  cell    super tableView tableView cellForRowAtIndexPath indexPath        if cell    self cellYouWantToHide          return 0    set the hidden cell s height to 0      return  super tableView tableView heightForRowAtIndexPath indexPath       Swift   override func tableView tableView  UITableView  heightForRowAtIndexPath indexPath  NSIndexPath  - gt  CGFloat       var cell   super tableView tableView  cellForRowAtIndexPath  indexPath       if cell    self cellYouWantToHide           return 0            return super tableView tableView  heightForRowAtIndexPath  indexPath      This method will get called for each cell in the UITable  Once it calls it for the cell you want to hide  we set its height to 0  We identify the target cell by creating an outlet for it    In the designer  create an outlet for the cell s  you want to hide  The outlet for one such cell is called  cellYouWantToHide  above  Check  Clip Subviews  in the IB for the cells you want to hide  The cells you are hiding need to have ClipToBounds   YES  Otherwise the text will pile up in the UITableView

Okay  after some trying  I have a non common answer  I am using the  isHidden  or  hidden  variable to check if this cell should be hidden    create an IBOutlet to your view controller   IBOutlet weak var myCell  UITableViewCell  Update the myCell in your custom function  example you may add it in viewDidLoad    override func viewDidLoad         super viewDidLoad       self myCell isHidden   true     in your delegate method    override func tableView   tableView  UITableView  heightForRowAt indexPath  IndexPath  - gt  CGFloat       let cell   super tableView tableView  cellForRowAt  indexPath      guard  cell isHidden else           return 0           return super tableView tableView  heightForRowAt  indexPath     This will reduce your logic in the delegate method  and you only need to focus on your business requirement

Yes  it s definitely possible  although I am struggling with the same issue at the moment  I ve managed to get the cells to hide and everything works ok  but I cannot currently make the thing animate neatly  Here is what I have found   I am hiding rows based on the state of an ON   OFF switch in the first row of the first section  If the switch is ON there is 1 row beneath it in the same section  otherwise there are 2 different rows   I have a selector called when the switch is toggled  and I set a variable to indicate which state I am in  Then I call     self tableView  reloadData     I override the tableView willDisplayCell forRowAtIndexPath  function and if the cell is supposed to be hidden I do this    cell setHidden YES     That hides the cell and its contents  but does not remove the space it occupies    To remove the space  override the tableView heightForRowAtIndexPath  function and return 0 for rows that should be hidden    You also need to override tableView numberOfRowsInSection  and return the number of rows in that section  You have to do something strange here so that if your table is a grouped style the rounded corners occur on the correct cells  In my static table there is the full set of cells for the section  so there is the first cell containing the option  then 1 cell for the ON state options and 2 more cells for the OFF state options  a total of 4 cells  When the option is ON  I have to return 4  this includes the hidden option so that the last option displayed has a rounded box  When the option is off  the last two options are not displayed so I return 2  This all feels clunky  Sorry if this isn t very clear  its tricky to describe  Just to illustrate the setup  this is the construction of the table section in IB    Row 0  Option with ON   OFF switch Row 1  Displayed when option is ON Row 2  Displayed when option is OFF Row 3  Displayed when option is OFF   So when the option is ON the table reports two rows which are    Row 0  Option with ON   OFF switch Row 1  Displayed when option is ON   When the option is OFF the table reports four rows which are    Row 0  Option with ON   OFF switch Row 1  Displayed when option is ON  Row 2  Displayed when option is OFF Row 3  Displayed when option is OFF   This approach doesn t feel correct for several reasons  its just as far as I have got with my experimentation so far  so please let me know if you find a better way  The problems I have observed so far are    It feels wrong to be telling the table the number of rows is different to what is presumably contained in the underlying data  I can t seem to animate the change  I ve tried using tableView reloadSections withRowAnimation  instead of reloadData and the results don t seem to make sense  I m still trying to get this working  Currently what seems to happen is the tableView does not update the correct rows so one remains hidden that should be displayed and a void is left under the first row  I think this might be related to the first point about the underlying data    Hopefully someone will be able to suggest alternative methods or perhaps how to extend with animation  but maybe this will get you started  My apologies for the lack of hyperlinks to functions  I put them in but they were rejected by the spam filter because I am a fairly new user

I came up with an alternative that actually hides sections and doesn t delete them  I tried  henning77 s approach  but I kept running into problems when I changed the number of sections of the static UITableView  This method has worked really well for me  but I m primarily trying to hide sections instead of rows  I am removing some rows on the fly successfully  but it is a lot messier  so I ve tried to group things into sections that I need to show or hide  Here is an example of how I m hiding sections   First I declare a NSMutableArray property   property  nonatomic  strong  NSMutableArray  hiddenSections    In the viewDidLoad  or after you have queried your data  you can add sections you want to hide to the array   -  void viewDidLoad       hiddenSections    NSMutableArray new        if some piece of data is empty              Add index of section that should be hidden          self hiddenSections addObject  NSNumber numberWithInt 1                   add as many sections to the array as needed       self tableView reloadData       Then implement the following the TableView delegate methods  -  NSString   tableView  UITableView   tableView titleForHeaderInSection  NSInteger section       if  self hiddenSections containsObject  NSNumber numberWithInt section             return nil             return  super tableView tableView titleForHeaderInSection section      -  CGFloat tableView  UITableView   tableView heightForRowAtIndexPath  NSIndexPath   indexPath       if  self hiddenSections containsObject  NSNumber numberWithInt indexPath section             return 0             return  super tableView tableView heightForRowAtIndexPath  self offsetIndexPath indexPath       -  void tableView  UITableView   tableView willDisplayCell  UITableViewCell   cell forRowAtIndexPath  NSIndexPath   indexPath       if  self hiddenSections containsObject  NSNumber numberWithInt indexPath section              cell setHidden YES             Then set the header and footer height to 1 for hidden sections because you can t set the height to 0  This causes an additional 2 pixel space  but we can make up for it by adjusting the height of the next visible header   - CGFloat tableView  UITableView   tableView heightForHeaderInSection  NSInteger section        CGFloat height    super tableView tableView heightForHeaderInSection section        if  self hiddenSections containsObject  NSNumber numberWithInt section             height   1     Can t be zero           else if  self tableView tableView titleForHeaderInSection section     nil      Only adjust if title is nil            Adjust height for previous hidden sections         CGFloat adjust   0           for int i    section - 1   i  gt   0  i--               if  self hiddenSections containsObject  NSNumber numberWithInt i                     adjust   adjust   2                            else                   break                                   if adjust  gt  0                                        if height    -1                   height   self tableView sectionHeaderHeight                             height   height - adjust               if height  lt  1                   height   1                                     return height     - CGFloat tableView  UITableView   tableView heightForFooterInSection  NSInteger section           if  self hiddenSections containsObject  NSNumber numberWithInt section             return 1            return  super tableView tableView heightForFooterInSection section       Then  if you do have specific rows to hide you can adjust the numberOfRowsInSection and which rows are returned in cellForRowAtIndexPath  In this example here I have a section that has three rows where any three could be empty and need to be removed   -

The best way is as described in the following blog http   ali-reynolds com 2013 06 29 hide-cells-in-static-table-view      Design your static table view as normal in interface builder       complete with all potentially hidden cells  But there is one thing you   must do for every potential cell that you want to hide     check the      Clip subviews    property of the cell  otherwise the content of the   cell doesn   t disappear when you try and hide it  by shrinking it   s   height     more later        SO     you have a switch in a cell and the switch is supposed to hide   and show some static cells  Hook it up to an IBAction and in there do   this    self tableView beginUpdates    self tableView endUpdates         That gives you nice animations for the cells appearing and   disappearing  Now implement the following table view delegate method   -  float tableView  UITableView   tableView heightForRowAtIndexPath  NSIndexPath   indexPath       if  indexPath section    1  amp  amp  indexPath row    1       This is the cell to hide - change as you need        Show or hide cell         if  self mySwitch on                return 44     Show the cell - adjust the height as you need           else               return 0     Hide the cell                   return 44          And that   s it  Flip the switch and the cell hides and reappears with a   nice  smooth animation

Simple iOS 11  amp  IB Storyboard Compatible Method  For iOS 11  I found that a modified version of Mohamed Saleh s answer worked best  with some improvements based on Apple s documentation  It animates nicely  avoids any ugly hacks or hardcoded values  and uses row heights already set in Interface Builder   The basic concept is to set the row height to 0 for any hidden rows  Then use tableView performBatchUpdates to trigger an animation that works consistently   Set the cell heights  override func tableView   tableView  UITableView  heightForRowAt indexPath  IndexPath  - gt  CGFloat       if indexPath    indexPathOfHiddenCell           if cellIsHidden               return 0                        Calling super will use the height set in your storyboard  avoiding hardcoded values     return super tableView tableView  heightForRowAt  indexPath      You ll want to make sure cellIsHidden and indexPathOfHiddenCell are set appropriately to your use case  For my code they re properties on my table view controller   Toggling the cell  In whatever method controls the visibility  likely a button action or didSelectRow   toggle the cellIsHidden state  inside a performBatchUpdates block   tableView performBatchUpdates                      Use self to capture for block                 self cellIsHidden    self cellIsHidden                 completion  nil    Apple recommends performBatchUpdates over beginUpdates endUpdates whenever possible

For the easiest scenario when you hide cells at the very bottom of table view  you could adjust tableView s contentInset after you hide cell   -  void adjustBottomInsetForHiddenSections  NSInteger numberOfHiddenSections       CGFloat bottomInset   numberOfHiddenSections   44 0     or any other  magic number     self tableView contentInset   UIEdgeInsetsMake self tableView contentInset top  self tableView contentInset left  -bottomInset  self tableView contentInset right

[ios] UITableView set to static cells. Is it possible to hide some of the cells programmatically?
