How to customize the background border colors of a grouped table view cell

Question

I would like to customize both the background and the border color of a grouped-style UITableView   I was able to customize the background color by using the following   tableView contentView backgroundColor    UIColor greenColor     But the border color is still something I don t know how to change   How do I customize these two aspects of the grouped-style table view

I know the answers are relating to changing grouped table cells, but in case someone is wanting to also change the tableview's background color:

Not only do you need to set:

tableview.backgroundColor = color;

You also need to change or get rid of the background view:

tableview.backgroundView = nil;

This task can be easily done using PrettyKit by adding about 5 lines of code  If you use nib files or storyboard  also do not forget to apply this little hack   When you use this approach  you should subclass your cell from PrettyTableViewCell    import  lt PrettyKit PrettyKit h gt    class RRSearchHistoryItem    interface RRSearchHistoryCell   PrettyTableViewCell   This is example of my cellForRowAtIndexPath   -  UITableViewCell   tableView  UITableView   tableView cellForRowAtIndexPath  NSIndexPath   indexPath     static NSString  cellIdentifier     RRSearchHistoryCell      RRSearchHistoryCell  cell    RRSearchHistoryCell    tableView dequeueReusableCellWithIdentifier cellIdentifier      if   cell    nil          NSArray  topLevelObjects     NSBundle mainBundle  loadNibNamed   RRSearchHistoryCell  owner self options nil       cell   topLevelObjects 0       cell gradientStartColor   RGB 0xffffff       cell gradientEndColor   RGB 0xf3f3f3           RRSearchHistoryItem  item    historyTableData indexPath row      cell setHistoryItem item        cell prepareForTableView tableView indexPath indexPath      return cell

UPDATE  In iPhone OS 3 0 and later UITableViewCell now has a backgroundColor property that makes this really easy  especially in combination with the  UIColor colorWithPatternImage   initializer   But I ll leave the 2 0 version of the answer here for anyone that needs it       It s harder than it really should be  Here s how I did this when I had to do it   You need to set the UITableViewCell s backgroundView property to a custom UIView that draws the border and background itself in the appropriate colors  This view needs to be able to draw the borders in 4 different modes  rounded on the top for the first cell in a section  rounded on the bottom for the last cell in a section  no rounded corners for cells in the middle of a section  and rounded on all 4 corners for sections that contain one cell   Unfortunately I couldn t figure out how to have this mode set automatically  so I had to set it in the UITableViewDataSource s -cellForRowAtIndexPath method   It s a real PITA but I ve confirmed with Apple engineers that this is currently the only way   Update Here s the code for that custom bg view  There s a drawing bug that makes the rounded corners look a little funny  but we moved to a different design and scrapped the custom backgrounds before I had a chance to fix it  Still this will probably be very helpful for you          CustomCellBackgroundView h        Created by Mike Akers on 11 21 08      Copyright 2008   MyCompanyName    All rights reserved       import  lt UIKit UIKit h gt   typedef enum        CustomCellBackgroundViewPositionTop       CustomCellBackgroundViewPositionMiddle       CustomCellBackgroundViewPositionBottom      CustomCellBackgroundViewPositionSingle   CustomCellBackgroundViewPosition    interface CustomCellBackgroundView   UIView       UIColor  borderColor      UIColor  fillColor      CustomCellBackgroundViewPosition position          property nonatomic  retain  UIColor  borderColor   fillColor       property nonatomic  CustomCellBackgroundViewPosition position   end         CustomCellBackgroundView m        Created by Mike Akers on 11 21 08      Copyright 2008   MyCompanyName    All rights reserved       import  CustomCellBackgroundView h   static void addRoundedRectToPath CGContextRef context  CGRect rect                                   float ovalWidth float ovalHeight     implementation CustomCellBackgroundView  synthesize borderColor  fillColor  position   -

Much thanks to all who posted their code   This is very useful   I derived a similar solution to change the highlight color for grouped table view cells   Basically the UITableViewCell s selectedBackgroundView  not the backgroundView    Which even on iPhone OS 3 0 still needs this PITA solution  as far as I can tell     The code below has the changes for rendering the highlight with a gradient instead of one solid color   Also the border rendering is removed   Enjoy          CSCustomCellBackgroundView h      import  lt UIKit UIKit h gt   typedef enum         CustomCellBackgroundViewPositionTop       CustomCellBackgroundViewPositionMiddle       CustomCellBackgroundViewPositionBottom      CustomCellBackgroundViewPositionSingle      CustomCellBackgroundViewPositionPlain   CustomCellBackgroundViewPosition    interface CSCustomCellBackgroundView   UIView        CustomCellBackgroundViewPosition position   CGGradientRef gradient      property nonatomic  CustomCellBackgroundViewPosition position    end           CSCustomCellBackgroundView m      import  CSCustomCellBackgroundView h      define ROUND SIZE 10   static void addRoundedRectToPath CGContextRef context  CGRect rect           float ovalWidth float ovalHeight      implementation CSCustomCellBackgroundView    synthesize position   -

Thanks for this super helpful post  In case anyone out there  like me   wants to just have a completely empty cell background in lieu of customizing it through images text other content in IB and cannot figure out how the hell to get rid of the dumb border padding background even though you set it to clear in IB    here s the code I used that did the trick    -  UITableViewCell    tableView   UITableView    tableView cellForRowAtIndexPath   NSIndexPath    indexPath        static NSString  cellId     cellId        UITableViewCell  cell    tableView dequeueReusableCellWithIdentifier  cellId       if  cell    nil              NSBundle mainBundle  loadNibNamed   EditTableViewCell  owner self options nil           cell   cellIBOutlet          self cellIBOutlet   nil             cell backgroundView      UIView alloc  initWithFrame  CGRectZero  autorelease        cell backgroundView setNeedsDisplay            any other cell customizations          return cell      Hopefully that ll help someone else  Seems to work like a charm

I have been having problems with this and tried lots of combinations of things as I noticed that for some cells it worked fine but not for others   Strangely I found out that it is possible to set the cell backgroundColor to lightGrayColor and all works perfectly - but blueColor caused me problems of not updating the outside edges   Unless it is really important to use green - perhaps you might want to try this  It might be that this is a feature to get people to use only grey colours when indicating a cell is selected

Thanks for this super helpful post  In case anyone out there  like me   wants to just have a completely empty cell background in lieu of customizing it through images text other content in IB and cannot figure out how the hell to get rid of the dumb border padding background even though you set it to clear in IB    here s the code I used that did the trick    -  UITableViewCell    tableView   UITableView    tableView cellForRowAtIndexPath   NSIndexPath    indexPath        static NSString  cellId     cellId        UITableViewCell  cell    tableView dequeueReusableCellWithIdentifier  cellId       if  cell    nil              NSBundle mainBundle  loadNibNamed   EditTableViewCell  owner self options nil           cell   cellIBOutlet          self cellIBOutlet   nil             cell backgroundView      UIView alloc  initWithFrame  CGRectZero  autorelease        cell backgroundView setNeedsDisplay            any other cell customizations          return cell      Hopefully that ll help someone else  Seems to work like a charm

One thing I ran into with the above CustomCellBackgroundView code from Mike Akers which might be useful to others   cell backgroundView doesn t get automatically redrawn when cells are reused  and changes to the backgroundView s position var don t affect reused cells  That means long tables will have incorrectly drawn cell backgroundViews given their positions   To fix this without having to create a new backgroundView every time a row is displayed  call  cell backgroundView setNeedsDisplay  at the end of your - UITableViewController tableView cellForRowAtIndexPath    Or for a more reusable solution  override CustomCellBackgroundView s position setter to include a  self setNeedsDisplay

This task can be easily done using PrettyKit by adding about 5 lines of code  If you use nib files or storyboard  also do not forget to apply this little hack   When you use this approach  you should subclass your cell from PrettyTableViewCell    import  lt PrettyKit PrettyKit h gt    class RRSearchHistoryItem    interface RRSearchHistoryCell   PrettyTableViewCell   This is example of my cellForRowAtIndexPath   -  UITableViewCell   tableView  UITableView   tableView cellForRowAtIndexPath  NSIndexPath   indexPath     static NSString  cellIdentifier     RRSearchHistoryCell      RRSearchHistoryCell  cell    RRSearchHistoryCell    tableView dequeueReusableCellWithIdentifier cellIdentifier      if   cell    nil          NSArray  topLevelObjects     NSBundle mainBundle  loadNibNamed   RRSearchHistoryCell  owner self options nil       cell   topLevelObjects 0       cell gradientStartColor   RGB 0xffffff       cell gradientEndColor   RGB 0xf3f3f3           RRSearchHistoryItem  item    historyTableData indexPath row      cell setHistoryItem item        cell prepareForTableView tableView indexPath indexPath      return cell

You can customize the border color by setting  tableView separatorColor

One thing I ran into with the above CustomCellBackgroundView code from Mike Akers which might be useful to others   cell backgroundView doesn t get automatically redrawn when cells are reused  and changes to the backgroundView s position var don t affect reused cells  That means long tables will have incorrectly drawn cell backgroundViews given their positions   To fix this without having to create a new backgroundView every time a row is displayed  call  cell backgroundView setNeedsDisplay  at the end of your - UITableViewController tableView cellForRowAtIndexPath    Or for a more reusable solution  override CustomCellBackgroundView s position setter to include a  self setNeedsDisplay

I know the answers are relating to changing grouped table cells, but in case someone is wanting to also change the tableview's background color:

Not only do you need to set:

tableview.backgroundColor = color;

You also need to change or get rid of the background view:

tableview.backgroundView = nil;

Much thanks to all who posted their code   This is very useful   I derived a similar solution to change the highlight color for grouped table view cells   Basically the UITableViewCell s selectedBackgroundView  not the backgroundView    Which even on iPhone OS 3 0 still needs this PITA solution  as far as I can tell     The code below has the changes for rendering the highlight with a gradient instead of one solid color   Also the border rendering is removed   Enjoy          CSCustomCellBackgroundView h      import  lt UIKit UIKit h gt   typedef enum         CustomCellBackgroundViewPositionTop       CustomCellBackgroundViewPositionMiddle       CustomCellBackgroundViewPositionBottom      CustomCellBackgroundViewPositionSingle      CustomCellBackgroundViewPositionPlain   CustomCellBackgroundViewPosition    interface CSCustomCellBackgroundView   UIView        CustomCellBackgroundViewPosition position   CGGradientRef gradient      property nonatomic  CustomCellBackgroundViewPosition position    end           CSCustomCellBackgroundView m      import  CSCustomCellBackgroundView h      define ROUND SIZE 10   static void addRoundedRectToPath CGContextRef context  CGRect rect           float ovalWidth float ovalHeight      implementation CSCustomCellBackgroundView    synthesize position   -
