iOS 8 UITableView separator inset 0 not working

Question

I have an app where the UITableView s separator inset is set to custom values - Right 0  Left 0  This works perfectly in iOS 7 x  however in iOS 8 0 I see that the separator inset is set to the default of 15 on the right  Even though in the xib files it set to 0  it still shows up incorrectly   How do I remove the UITableViewCell separator margins

This is the code that s working for me  in Swift   override func viewDidLoad          super viewDidLoad               if tableView respondsToSelector  setSeparatorInset              tableView separatorInset   UIEdgeInsetsZero          func tableView tableView  UITableView  willDisplayCell cell  UITableViewCell forRowAtIndexPath indexPath  NSIndexPath        if cell respondsToSelector  setSeparatorInset              cell separatorInset left   CGFloat 0 0            if tableView respondsToSelector  setLayoutMargins              tableView layoutMargins   UIEdgeInsetsZero           if cell respondsToSelector  setLayoutMargins              cell layoutMargins left   CGFloat 0 0            This seems the cleanest to me  for now   as all the cell tableView edge margin adjustments are done in the tableView willDisplayCell forRowAtIndexPath  method  without cramming unneccessary code into tableView cellForRowAtIndexPath    Btw  I m only setting the cell s left separatorInset layoutMargins  because in this case I don t want to screw up my constraints that I have set up in my cell   Code updated to Swift 2 2     override func viewDidLoad        super viewDidLoad               if tableView respondsToSelector Selector  setSeparatorInset             tableView separatorInset   UIEdgeInsetsZero                   override func tableView tableView  UITableView  willDisplayCell cell  UITableViewCell forRowAtIndexPath indexPath  NSIndexPath            if cell respondsToSelector Selector  setSeparatorInset                   cell separatorInset left   CGFloat 0 0                    if tableView respondsToSelector Selector  setLayoutMargins                   tableView layoutMargins   UIEdgeInsetsZero                   if cell respondsToSelector Selector  setLayoutMargins                   cell layoutMargins left   CGFloat 0 0

Let s take a moment to understand the problem before blindly charging in to attempt to fix it   A quick poke around in the debugger will tell you that separator lines are subviews of UITableViewCell  It seems that the cell itself takes a fair amount of responsibility for the layout of these lines   iOS 8 introduces the concept of layout margins  By default  a view s layout margins are 8pt on all sides  and they re inherited from ancestor views   As best we can tell  when laying out out its separator line  UITableViewCell chooses to respect the left-hand layout margin  using it to constrain the left inset   Putting all that together  to achieve the desired inset of truly zero  we need to    Set the left layout margin to 0 Stop any inherited margins overriding that   Put like that  it s a pretty simple task to achieve   cell layoutMargins   UIEdgeInsetsZero  cell preservesSuperviewLayoutMargins   NO    Things to note    This code only needs to be run once per cell  you re just configuring the cell s properties after all   and there s nothing special about when you choose to execute it  Do what seems cleanest to you  Sadly neither property is available to configure in Interface Builder  but you can specify a user-defined runtime attribute for preservesSuperviewLayoutMargins if desired  Clearly  if your app targets earlier OS releases too  you ll need to avoid executing the above code until running on iOS 8 and above  Rather than setting preservesSuperviewLayoutMargins  you can configure ancestor views  such as the table  to have 0 left margin too  but this seems inherently more error-prone as you don t control that entire hierarchy  It would probably be slightly cleaner to set only the left margin to 0 and leave the others be  If you want to have a 0 inset on the  extra  separators that UITableView draws at the bottom of plain style tables  I m guessing that will require specifying the same settings at the table level too  haven t tried this one

After much investigation    Here s the only way to fully control this stuff  that I could find  To fully control both separator insets and layout margins on each cell  Do this in the willDisplayCell method on your UITableviewDelegate  func tableView tableView  UITableView  willDisplayCell cell  UITableViewCell  forRowAtIndexPath indexPath  NSIndexPath        cell layoutMargins   UIEdgeInsetsZero     cell contentView layoutMargins   UIEdgeInsetsMake 0  10  0  10      cell separatorInset   UIEdgeInsetsMake 0  0  0  0     The cell object controls the separator  and the contentView controls everything else  If your separator inset spaces are showing up in an unexpected color this should solve it  cell backgroundColor   cell contentView backgroundColor

iOS introduces the layoutMargins property on cells AND table views   This property isn t available in iOS 7 0 so you need to make sure you check before assigning it   However  Apple has added a property called preservesSuperviewLayoutMargins to your cell that will prevent it from inheriting your Table View s margin settings  This way  your cells can configure their own margins independently of the table view  Think of it as an override   This property is called preservesSuperviewLayoutMargins  and setting it to NO can allow you to override your Table View s layoutMargin settings with your own cell s layoutMargin setting  It both saves time  you don t have to modify the Table View s settings   and is more concise  Please refer to Mike Abdullah s answer for a detailed explanation   NOTE  this is the proper  less messy implementation  as expressed in Mike Abdullah s answer  setting your cell s preservesSuperviewLayoutMargins NO will ensure that your Table View does not override the cell settings   First step - Setup your cell margins          Tells the delegate that the table view is about to draw a cell for a particular row     override func tableView tableView  UITableView  willDisplayCell cell  UITableViewCell      forRowAtIndexPath indexPath  NSIndexPath           Remove separator inset     if cell respondsToSelector  setSeparatorInset              cell separatorInset   UIEdgeInsetsZero               Prevent the cell from inheriting the Table View s margin settings     if cell respondsToSelector  setPreservesSuperviewLayoutMargins              cell preservesSuperviewLayoutMargins   false               Explictly set your cell s layout margins     if cell respondsToSelector  setLayoutMargins              cell layoutMargins   UIEdgeInsetsZero           Setting the preservesSuperviewLayoutMargins property on your cell to NO should prevent your table view from overriding your cell margins  In some cases  it seems not to function properly   Second step - Only if all fails  you may brute-force your Table View margins          Called to notify the view controller that its view has just laid out its subviews     override func viewDidLayoutSubviews         super viewDidLayoutSubviews           Force your tableview margins  this may be a bad idea      if self tableView respondsToSelector  setSeparatorInset              self tableView separatorInset   UIEdgeInsetsZero            if self tableView respondsToSelector  setLayoutMargins              self tableView layoutMargins   UIEdgeInsetsZero              and there you go  This should work on iOS 8 as well as iOS 7   Note  tested using iOS 8 1 and 7 1  in my case I only needed to use the first step of this explanation   The Second Step is only required if you have unpopulated cell beneath the rendered cells  ie  if the table is larger than the number of rows in the table model  Not doing the second step would result in different separator offsets

iOS 8 0 introduces the layoutMargins property on cells AND table views   This property isn t available on iOS 7 0 so you need to make sure you check before assigning it   The easy fix is to subclass your cell and override the layout margins property as suggested by  user3570727  However you will lose any system behavior like inheriting margins from the Safe Area so I do not recommend the below solution    ObjectiveC   - UIEdgeInsets layoutMargins         return UIEdgeInsetsZero    override any margins inc  safe area      swift 4 2    override var layoutMargins  UIEdgeInsets   get   return  zero   set         If you don t want to override the property  or need to set it conditionally  keep reading     In addition to the layoutMargins property  Apple has added a property to your cell that will prevent it from inheriting your Table View s margin settings  When this property is set  your cells are allowed to configure their own margins independently of the table view  Think of it as an override   This property is called preservesSuperviewLayoutMargins  and setting it to NO will allow the cell s layoutMargin setting to override whatever layoutMargin is set on your TableView  It both saves time  you don t have to modify the Table View s settings   and is more concise  Please refer to Mike Abdullah s answer for a detailed explanation   NOTE  what follows is a clean implementation for a cell-level margin setting  as expressed in Mike Abdullah s answer  Setting your cell s preservesSuperviewLayoutMargins NO will ensure that your Table View does not override the cell settings  If you actually want your entire table view to have consistent margins  please adjust your code accordingly   Setup your cell margins   - void tableView  UITableView   tableView willDisplayCell  UITableViewCell   cell forRowAtIndexPath  NSIndexPath   indexPath          Remove seperator inset     if   cell respondsToSelector  selector setSeparatorInset                   cell setSeparatorInset UIEdgeInsetsZero                 Prevent the cell from inheriting the Table View s margin settings     if   cell respondsToSelector  selector setPreservesSuperviewLayoutMargins                cell setPreservesSuperviewLayoutMargins NO                 Explictly set your cell s layout margins     if   cell respondsToSelector  selector setLayoutMargins                cell setLayoutMargins UIEdgeInsetsZero             Swift 4   func tableView   tableView  UITableView  willDisplay cell  UITableViewCell  forRowAt indexPath  IndexPath           Remove seperator inset     if cell responds to   selector setter  UITableViewCell separatorInset             cell separatorInset    zero              Prevent the cell from inheriting the Table View s margin settings     if cell responds to   selector setter  UITableViewCell preservesSuperviewLayoutMargins             cell preservesSuperviewLayoutMargins   false              Explictly set your cell s layout margins     if cell responds to   selector setter  UITableViewCell layoutMargins             cell layoutMargins    zero           Setting the preservesSuperviewLayoutMargins property on your cell to NO should prevent your table view from overriding your cell margins  In some cases  it seems to not function properly   If all fails  you may brute-force your Table View margins   - void viewDidLayoutSubviews        super viewDidLayoutSubviews           Force your tableview margins  this may be a bad idea      if   self tableView respondsToSelector  selector setSeparatorInset                self tableView setSeparatorInset UIEdgeInsetsZero              if   self tableView respondsToSelector  selector setLayoutMargins                self tableView setLayoutMargins UIEdgeInsetsZero              Swift 4   func viewDidLayoutSubviews         super viewDidLayoutSubviews          Force your tableview margins  this may be a bad idea      if tableView responds to   selector setter  UITableView separatorInset             tableView separatorInset    zero           if tableView responds to   selector setter  UITableView layoutMargins             tableView layoutMargins    zero              and there you go  This should work on iOS 7 and 8     EDIT  Mohamed Saleh brought to my attention a possible change in iOS 9  You may need to set the Table View s cellLayoutMarginsFollowReadableWidth to NO if you want to customize insets or margins  Your mileage may vary  this is not documented very well   This property only exists in iOS 9 so be sure to check before setting   if  myTableView respondsToSelector  selector setCellLayoutMarginsFollowReadableWidth           myTableView cellLayoutMarginsFollowReadableWidth   NO       Swift 4   if myTableView responds to   selector setter  self cellLayoutMarginsFollowReadableWidth         myTableView cellLayoutMarginsFollowReadableWidth   false      above code from iOS 8 UITableView separator inset 0 not working   EDIT  Here s a pure Interface Builder approach      NOTE  iOS 11 changes  amp  simplifies much of this behavior  an update will be forthcoming

I didn t have any real luck with any of the solutions above   I m using NIB files for my tables cells   I  fixed  this by adding a label with a height of 1   I changed the background of the label to black  pinned the label to the bottom of the nib  and then pinned the bottom of the rest of my contents to the added label    Now I have a black border running along the bottom of my cells   To me  this feels like more of a hack  but it does work   My only other choice was to just eliminate the border completely   I m still deciding whether I ll just go with that

Instead of updating preservesSuperviewLayoutMargins and layoutMargins every time the cell scrolls in  using willDisplayCell   I d suggest to do it once in cellForRowAtIndexPath    override func tableView tableView  UITableView  cellForRowAtIndexPath indexPath  NSIndexPath  - gt  UITableViewCell        let cell   super tableView tableView  cellForRowAtIndexPath  indexPath       cell preservesSuperviewLayoutMargins   false     cell layoutMargins   UIEdgeInsetsZero      return cell

In Swift it s slightly more annoying because layoutMargins is a property  so you have to override the getter and setter   override var layoutMargins  UIEdgeInsets     get   return UIEdgeInsetsZero     set newVal         This will effectively make layoutMargins readonly  which in my case is fine

After having seen the answers at floor 3  I tried to figure out what the relationship of setting up the separator between TableView  amp  TableViewCell and did some test  Here are my conclusions    we can consider that setting the cell s separator to zero has to move the separator in two steps  first step is to set cell s separatorinset to zero  second step is to set cell s marginlayout to zero  set the TableView s separatorinset and marginlayout can affect the Cell s separatorinset  However  from the test  I find that the TableView s separatorinset seem to be useless  TableView s marginlayout can actually affect cell s marginlayout  set Cell s PreservesSuperviewLayoutMargins   false  can cut off TableView s marginlayout effect on Cells  one of the solutions    func tableView tableView  UITableView  cellForRowAtIndexPath indexPath  NSIndexPath  - gt  UITableViewCell       var cell   UITableViewCell        cell preservesSuperviewLayoutMargins   false     cell separatorInset   UIEdgeInsetsZero     cell layoutMargins   UIEdgeInsetsZero      return cell

Arg    After playing around either doing this in your Cell subclass    -  UIEdgeInsets layoutMargins       return UIEdgeInsetsZero      or setting the cell layoutMargins   UIEdgeInsetsZero  fixed it for me

This is my solution  This applies to the custom cell subclass  just add them both to the subclass    -  UIEdgeInsets layoutMargins           return UIEdgeInsetsMake 0  10  0  10        2   self separatorInset   UIEdgeInsetsMake 0  10  0  10     And it is convenient that you can customize the position of the separator without asking your designer to draw one for you

I believe this is the same question that I asked here  Remove SeparatorInset on iOS 8 UITableView for XCode 6 iPhone Simulator  In iOS 8  there is one new property for all the objects inherit from UIView  So  the solution to set the SeparatorInset in iOS 7 x will not be able to remove the white space you see on the UITableView in iOS 8    The new property is called  layoutMargins     property nonatomic  UIEdgeInsets layoutMargins Description   The default spacing to use when laying out content in the view  Availability  iOS  8 0 and later  Declared In   UIView h Reference UIView Class Reference     The solution -  - void tableView  UITableView   tableView willDisplayCell  UITableViewCell   cell forRowAtIndexPath  NSIndexPath   indexPath       if   tableView respondsToSelector  selector setSeparatorInset                tableView setSeparatorInset UIEdgeInsetsZero              if   tableView respondsToSelector  selector setLayoutMargins                tableView setLayoutMargins UIEdgeInsetsZero             if   cell respondsToSelector  selector setLayoutMargins                cell setLayoutMargins UIEdgeInsetsZero            If you set cell layoutMargins   UIEdgeInsetsZero  without checking if the layoutMargins exists  the app will crash on iOS 7 x  So  the best way would be checking if  the layoutMargins exists first before setLayoutMargins UIEdgeInsetsZero

following answer from  cdstamper  a better place is layoutSubviews of UITableViewCell  in your cell file I set 1  spacing  you can set to zero   so need only to set code here to handle all situations rotate and other     - void layoutSubviews                super layoutSubviews           if   self respondsToSelector  selector setSeparatorInset                    self setSeparatorInset UIEdgeInsetsMake 0 self bounds size width 0 01 0 self bounds size width 0 01                      if   self respondsToSelector  selector setLayoutMargins                    self setLayoutMargins UIEdgeInsetsMake 0 self bounds size width 0 01 0 self bounds size width 0 01

With Swift 2 2  create UITableViewCell extension  import UIKit  extension UITableViewCell       func removeMargins              if self respondsToSelector Selector  setSeparatorInset                   self separatorInset   UIEdgeInsetsZero                    if self respondsToSelector Selector  setPreservesSuperviewLayoutMargins                   self preservesSuperviewLayoutMargins   false                    if self respondsToSelector Selector  setLayoutMargins                   self layoutMargins   UIEdgeInsetsZero                      Now you can use in your cellForRowAtIndex  - void tableView  UITableView   tableView willDisplayCell  UITableViewCell   cell forRowAtIndexPath  NSIndexPath   indexPath               cell removeMargins    To remove seprator inset

Most answers are showing separator insets and layout margins being set over a variety of methods  i e   viewDidLayoutSubviews  willDisplayCell  etc  for cells and tableviews  but I ve found that just putting these in cellForRowAtIndexPath works great  Seems like the cleanest way      kill insets for iOS 8 if    UIDevice currentDevice  systemVersion floatValue   gt   8        cell preservesSuperviewLayoutMargins   NO       cell setLayoutMargins UIEdgeInsetsZero        iOS 7 and later if   cell respondsToSelector  selector setSeparatorInset          cell setSeparatorInset UIEdgeInsetsZero

You can use UIAppearance once  at your application startup  before UI is loaded   to set it as default global settings      iOS 7    UITableView appearance  setSeparatorStyle UITableViewCellSeparatorStyleSingleLine     UITableView appearance  setSeparatorInset UIEdgeInsetsZero      UITableViewCell appearance  setSeparatorInset UIEdgeInsetsZero       iOS 8  if   UITableView instancesRespondToSelector  selector setLayoutMargins              UITableView appearance  setLayoutMargins UIEdgeInsetsZero         UITableViewCell appearance  setLayoutMargins UIEdgeInsetsZero         UITableViewCell appearance  setPreservesSuperviewLayoutMargins NO        This way  you keep your UIViewController s code clean and can always override it if you want

In a more compact way than the most voted answer     -  void tableView  UITableView   tableView willDisplayCell  UITableViewCell   cell forRowAtIndexPath  NSIndexPath   indexPath        if   cell respondsToSelector  selector setSeparatorInset     amp  amp   cell respondsToSelector  selector setPreservesSuperviewLayoutMargins     amp  amp   cell respondsToSelector  selector setLayoutMargins                 cell setSeparatorInset UIEdgeInsetsZero             cell setPreservesSuperviewLayoutMargins NO             cell setLayoutMargins UIEdgeInsetsZero
