Detecting which UIButton was pressed in a UITableView

Question

I have a UITableView with 5 UITableViewCells  Each cell contains a UIButton which is set up as follows   -  UITableViewCell   tableView  UITableView   tableView cellForRowAtIndexPath  NSIndexPath   indexPath        NSString  identifier     identifier        UITableViewCell  cell    tableView dequeueReusableCellWithIdentifier identifier        if  cell    nil             cell     UITableView alloc  initWithStyle UITableViewCellStyleDefault reuseIdentifier identifier             cell autorelelase             UIButton  button     UIButton alloc  initWithFrame CGRectMake 10  5  40  20              button addTarget self action  selector buttonPressedAction   forControlEvents UIControlEventTouchUpInside             button setTag 1             cell contentView addSubview button              button release                UIButton  button    UIButton    cell viewWithTag 1         button setTitle   Edit  forState UIControlStateNormal         return cell      My question is this  in the buttonPressedAction  method  how do I know which button has been pressed  I ve considered using tags but I m not sure this is the best route  I d like to be able to somehow tag the indexPath onto the control   -  void buttonPressedAction  id sender       UIButton  button    UIButton   sender         how do I know which button sent this message         processing button press for this row requires an indexPath       What s the standard way of doing this   Edit   I ve kinda solved it by doing the following  I would still like to have an opinion whether this is the standard way of doing it or is there a better way   -  UITableViewCell   tableView  UITableView   tableView cellForRowAtIndexPath  NSIndexPath   indexPath        NSString  identifier     identifier        UITableViewCell  cell    tableView dequeueReusableCellWithIdentifier identifier        if  cell    nil             cell     UITableView alloc  initWithStyle UITableViewCellStyleDefault reuseIdentifier identifier             cell autorelelase             UIButton  button     UIButton alloc  initWithFrame CGRectMake 10  5  40  20              button addTarget self action  selector buttonPressedAction   forControlEvents UIControlEventTouchUpInside             cell contentView addSubview button              button release                UIButton  button    UIButton    cell contentView subviews objectAtIndex 0         button setTag indexPath row         button setTitle   Edit  forState UIControlStateNormal         return cell     -  void buttonPressedAction  id sender       UIButton  button    UIButton   sender      int row   button tag      What s important to note is that I can t set the tag in the creation of the cell since the cell might be dequeued instead  It feels very dirty  There must be a better way

TO HANDLE SECTIONS - I stored the NSIndexPath in a custom UITableViewCell

IN CLKIndexPricesHEADERTableViewCell.xib

IN IB Add UIButton to XIB - DONT add action!

Add outlet @property (retain, nonatomic) IBOutlet UIButton *buttonIndexSectionClose;

DO NOT CTRL+DRAG an action in IB(done in code below)

@interface CLKIndexPricesHEADERTableViewCell : UITableViewCell
...
@property (retain, nonatomic) IBOutlet UIButton *buttonIndexSectionClose;
@property (nonatomic, retain) NSIndexPath * indexPathForCell;
@end

In viewForHeaderInSection (should also work for cellForRow.... etc if you table has only 1 section)

- viewForHeaderInSection is called for each section 1...2...3
- get the cell CLKIndexPricesHEADERTableViewCell 
- getTableRowHEADER just does the normal dequeueReusableCellWithIdentifier
- STORE the indexPath IN the UITableView cell
- indexPath.section = (NSInteger)section
- indexPath.row = 0 always (we are only interested in sections)

- (UIView *) tableView:(UITableView *)tableView1 viewForHeaderInSection:(NSInteger)section {


    //Standard method for getting a UITableViewCell
    CLKIndexPricesHEADERTableViewCell * cellHEADER = [self getTableRowHEADER];

...use the section to get data for your cell

...fill it in

   indexName        = ffaIndex.routeCode;
   indexPrice       = ffaIndex.indexValue;

   //

   [cellHEADER.buttonIndexSectionClose addTarget:self
                                          action:@selector(buttonDELETEINDEXPressedAction:forEvent:)
                                forControlEvents:UIControlEventTouchUpInside];


   cellHEADER.indexPathForCell = [NSIndexPath indexPathForRow:0 inSection:section];


    return cellHEADER;
}

USER presses DELETE Button on a Section header and this calls

- (void)buttonDELETEINDEXPressedAction:(id)sender forEvent:(UIEvent *)event
{
    NSLog(@"%s", __PRETTY_FUNCTION__);


    UIView *  parent1 = [sender superview];   // UiTableViewCellContentView
    //UIView *myContentView = (UIView *)parent1;

    UIView *  parent2 = [parent1 superview];  // custom cell containing the content view
    //UIView *  parent3 = [parent2 superview];  // UITableView containing the cell
    //UIView *  parent4 = [parent3 superview];  // UIView containing the table


    if([parent2 isMemberOfClass:[CLKIndexPricesHEADERTableViewCell class]]){
        CLKIndexPricesHEADERTableViewCell *myTableCell = (CLKIndexPricesHEADERTableViewCell *)parent2;

        //UITableView *myTable = (UITableView *)parent3;
        //UIView *mainView = (UIView *)parent4;

        NSLog(@"%s indexPath.section,row[%d,%d]", __PRETTY_FUNCTION__, myTableCell.indexPathForCell.section,myTableCell.indexPathForCell.row);

        NSString *key = [self.sortedKeysArray objectAtIndex:myTableCell.indexPathForCell.section];
        if(key){
            NSLog(@"%s DELETE object at key:%@", __PRETTY_FUNCTION__,key);
            self.keyForSectionIndexToDelete = key;
            self.sectionIndexToDelete = myTableCell.indexPathForCell.section;

            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Remove Index"
                                                                message:@"Are you sure"
                                                               delegate:self
                                                      cancelButtonTitle:@"No"
                                                      otherButtonTitles:@"Yes", nil];
            alertView.tag = kALERTVIEW_REMOVE_ONE_INDEX;
            [alertView show];
            [alertView release];
            //------
        }else{
            NSLog(@"ERROR: [%s] key is nil for section:%d", __PRETTY_FUNCTION__,myTableCell.indexPathForCell.section);
        }

    }else{
        NSLog(@"ERROR: [%s] CLKIndexPricesHEADERTableViewCell not found", __PRETTY_FUNCTION__);
    }
}

In this example I added a Delete button so should show UIAlertView to confirm it

I store the section and key into the dictionary storing info about the section in a ivar in the VC

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
   if(alertView.tag == kALERTVIEW_REMOVE_ONE_INDEX){
        if(buttonIndex==0){
            //NO
            NSLog(@"[%s] BUTTON:%d", __PRETTY_FUNCTION__,buttonIndex);
            //do nothing
        }
        else if(buttonIndex==1){
            //YES
            NSLog(@"[%s] BUTTON:%d", __PRETTY_FUNCTION__,buttonIndex);
            if(self.keyForSectionIndexToDelete != nil){

                //Remove the section by key
                [self.indexPricesDictionary removeObjectForKey:self.keyForSectionIndexToDelete];

                //sort the keys so sections appear alphabetically/numbericsearch (minus the one we just removed)
                [self updateTheSortedKeysArray];                

                //Delete the section from the table using animation
                [self.tableView beginUpdates];

                [self.tableView deleteSections:[NSIndexSet indexSetWithIndex:self.sectionIndexToDelete]
                              withRowAnimation:UITableViewRowAnimationAutomatic];
                [self.tableView endUpdates];

                //required to trigger refresh of myTableCell.indexPathForCell else old values in UITableViewCells
                [self.tableView reloadData];
            }else{
                NSLog(@"ERROR: [%s] OBJECT is nil", __PRETTY_FUNCTION__);
            }
        }
        else {
            NSLog(@"ERROR: [%s] UNHANDLED BUTTON:%d", __PRETTY_FUNCTION__,buttonIndex);
        }
    }else {
        NSLog(@"ERROR: [%s] unhandled ALERTVIEW TAG:%d", __PRETTY_FUNCTION__,alertView.tag);
    }
}

In Apple s Accessory sample the following method is used    button addTarget self action  selector checkButtonTapped   forControlEvents UIControlEventTouchUpInside     Then in touch handler touch coordinate retrieved and index path is calculated from that coordinate    -  void checkButtonTapped  id sender       CGPoint buttonPosition    sender convertPoint CGPointZero toView self tableView       NSIndexPath  indexPath    self tableView indexPathForRowAtPoint buttonPosition       if  indexPath    nil

How about sending the information like NSIndexPath in the UIButton using runtime injection   1  You need runtime on the import  2  add static constant  3  add NSIndexPath to your button on runtime using    void setMetaData  id target withObject  id newObj  4  on button press get metadata using    id metaData  id target  Enjoy       import  lt objc runtime h gt      static char const   const kMetaDic    kMetaDic          pragma mark - Getters   Setters  -  id metaData  id target       return objc getAssociatedObject target  kMetaDic      -  void setMetaData  id target withObject  id newObj       objc setAssociatedObject target  kMetaDic  newObj  OBJC ASSOCIATION RETAIN NONATOMIC             On the cell constructor     -  UITableViewCell   tableView  UITableView   tableView cellForRowAtIndexPath  NSIndexPath   indexPath                    cell    tableView dequeueReusableCellWithIdentifier CellIdentifier                 btnSocial addTarget self                                    action  selector openComments                            forControlEvents UIControlEventTouchUpInside         add the indexpath here or another object      self setMetaData btnSocial withObject indexPath                           The action after button been press       -  IBAction openComments  UIButton  sender           NSIndexPath  indexPath    self metaData sender           NSLog   indexPath   d   indexPath row              Reuse your indexpath Now

I found the method of using the superview s superview to obtain a reference to the cell s indexPath worked perfectly  Thanks to iphonedevbook com  macnsmith  for the tip link text  - void buttonPressed  id sender    UITableViewCell  clickedCell    UITableViewCell     sender superview  superview    NSIndexPath  clickedButtonPath    self tableView indexPathForCell clickedCell

Am I missing something   Can t you just use sender to identify the button   Sender will give you info like this    lt UIButton  0x4b95c10  frame    246 26  30 30   opaque   NO  tag   104  layer    lt CALayer  0x4b95be0 gt  gt    Then if you want to change the properties of the button  say the background image you just tell sender    sender setBackgroundImage  UIImage imageNamed   new-image png   forState UIControlStateNormal     If you need the tag then ACBurk s method is fine

I use a solution that subclass UIButton and I thought I should just share it here  codes in Swift   class ButtonWithIndexPath   UIButton       var indexPath IndexPath      Then remember to update it s indexPath in cellForRow at    func tableView   tableView  UITableView  cellForRowAt indexPath  IndexPath  - gt  UITableViewCell        let returnCell   tableView dequeueReusableCell withIdentifier   cellWithButton   for  indexPath  as  cellWithButton             returnCell button indexPath   IndexPath     returnCell button addTarget self  action  selector cellButtonPressed       for   touchUpInside       return returnCell     So when responding to the button s event you can use it like  func cellButtonPressed   sender UIButton        if sender is ButtonWithIndexPath           let button   sender as  ButtonWithIndexPath         print button indexPath

Found a nice solution to this problem elsewhere  no messing around with tags on the button   -  void buttonPressedAction  id sender        NSSet  touches    event allTouches       UITouch  touch    touches anyObject       CGPoint currentTouchPosition    touch locationInView self tableView       NSIndexPath  indexPath    self tableView indexPathForRowAtPoint  currentTouchPosition           do stuff with the indexPath

Though I like the tag way    if you don t want to use tags for whatever reason  you could create a member NSArray of premade buttons   NSArray  buttons     then create those buttons before rendering the tableView and push them into the array   Then inside of the tableView cellForRowAtIndexPath  function you can do   UIButton  button    buttons objectAtIndex  indexPath row       cell contentView addSubview button     Then in the buttonPressedAction  function  you can do  -  void buttonPressedAction  id sender      UIButton  button    UIButton  sender      int row    buttons indexOfObject button          Do magic

I would use the tag property like you said  setting the tag like so    button setTag indexPath row     then getting the tag inside of the buttonPressedAction like so     UIButton   sender  tag   Or  UIButton  button    UIButton   sender   button tag

A slight variation on Cocoanuts answer  that helped me solve this  when the button was in the footer of a table  which prevents you from finding the  clicked cell    - IBAction  buttonAction  id sender        id parent1    sender superview        UiTableViewCellContentView     id parent2    parent1 superview       custom cell containing the content view     id parent3    parent2 superview       UITableView containing the cell     id parent4    parent3 superview       UIView containing the table      UIView  myContentView    UIView   parent1      UITableViewCell  myTableCell    UITableViewCell   parent2      UITableView  myTable    UITableView   parent3      UIView  mainView    UIView   parent4       CGRect footerViewRect   myTableCell frame      CGRect rect3    myTable convertRect footerViewRect toView mainView             cc doSomethingOnScreenAtY rect3 origin y

you can use the tag pattern   -  UITableViewCell   tableView  UITableView   tableView cellForRowAtIndexPath  NSIndexPath   indexPath        NSString  identifier     identifier        UITableViewCell  cell    tableView dequeueReusableCellWithIdentifier identifier        if  cell    nil             cell     UITableView alloc  initWithStyle UITableViewCellStyleDefault reuseIdentifier identifier             cell autorelelase             UIButton  button     UIButton alloc  initWithFrame CGRectMake 10  5  40  20              button addTarget self action  selector buttonPressedAction   forControlEvents UIControlEventTouchUpInside             button setTag  indexPath row      use the row as the current tag           cell contentView addSubview button              button release                UIButton  button    UIButton    cell viewWithTag  indexPath row      use  indexPath row        button setTitle   Edit  forState UIControlStateNormal         return cell     -  void buttonPressedAction  id sender       UIButton  button    UIButton   sender        button tag has the row number  you can convert it to indexPath

SWIFT 2 UPDATE  Here s how to find out which button was tapped   send data to another ViewController from that button s indexPath row as I m assuming that s the point for most      IBAction func yourButton sender  AnyObject           var position  CGPoint   sender convertPoint CGPointZero  toView  self tableView          let indexPath   self tableView indexPathForRowAtPoint position          let cell  UITableViewCell   tableView cellForRowAtIndexPath indexPath    as         UITableViewCell         print indexPath  row          print  Tap tap tap tap            For those who are using a ViewController class and added a tableView  I m using a ViewController instead of a TableViewController so I manually added the tableView in order to access it   Here is the code for passing data to another VC when tapping that button and passing the cell s  indexPath row    IBAction func moreInfo sender  AnyObject         let yourOtherVC   self storyboard  instantiateViewControllerWithIdentifier  yourOtherVC   as  YourOtherVCVIewController        var position  CGPoint   sender convertPoint CGPointZero  toView  self tableView      let indexPath   self tableView indexPathForRowAtPoint position      let cell  UITableViewCell   tableView cellForRowAtIndexPath indexPath    as     UITableViewCell     print indexPath  row      print  Button tapped         yourOtherVC yourVarName    self otherVCVariable indexPath  row        self presentViewController yourNewVC  animated  true  completion  nil

It s simple  make a custom cell and take a outlet of button  -  UITableViewCell   tableView  UITableView   tableView cellForRowAtIndexPath  NSIndexPath   indexPath                NSString  identifier     identifier           customCell  cell    tableView dequeueReusableCellWithIdentifier identifier        cell yourButton tag   indexPath Row   -  void buttonPressedAction  id sender   change id in above method to  UIButton     You can get the value that which button is being tapped by doing sender tag

This problem has two parts   1  Getting the index path of UITableViewCell which contains pressed UIButton  There are some suggestions like    Updating UIButton s tag in cellForRowAtIndexPath  method using index path s row value  This is not an good solution as it requires updating tag continuously and it does not work with table views with more than one section   Adding an NSIndexPath property to custom cell and updating it instead of UIButton s tag in cellForRowAtIndexPath  method  This solves multiple section problem but still not good as it requires updating always  Keeping a weak refence to parent UITableView in the custom cell while creating it and using indexPathForCell  method to get the index path  Seems a little bit better  no need to update anything in cellForRowAtIndexPath  method  but still requires setting a weak reference when the custom cell is created  Using cell s superView property to get a reference to parent UITableView  No need to add any properties to the custom cell  and no need to set update anything on creation later  But cell s superView depends on iOS implementation details  So it can not be used directly    But this can be achieved using a simple loop  as we are sure the cell in question has to be in a UITableView   UIView  view   self  while  view  amp  amp    view isKindOfClass UITableView class       view   view superview  UITableView  parentTableView    UITableView  view    So  these suggestions can be combined into a simple and safe custom cell method for getting the index path   -  NSIndexPath   indexPath       UIView  view   self       while  view  amp  amp    view isKindOfClass UITableView class           view   view superview       return   UITableView  view indexPathForCell self       From now on  this method can be used to detect which UIButton is pressed   2  Informing other parties about button press event  After internally knowing which UIButton is pressed in which custom cell with exact index path  this information needs to be sent to other parties  most probably the view controller handling the UITableView   So  this button click event can be handled in a similar abstraction and logic level to didSelectRowAtIndexPath  method of UITableView delegate   Two approaches can be used for this    a  Delegation  custom cell can have a delegate property and can define a protocol  When button is pressed it just performs it s delegate methods on it s delegate property  But this delegate property needs to be set for each custom cell when they are created  As an alternative  custom cell can choose to perform its delegate methods on it s parent table view s delegate too   b  Notification Center  custom cells can define a custom notification name and post this notification with the index path and parent table view information provided in userInfo object  No need to set anything for each cell  just adding an observer for the custom cell s notification is enough

A better way would be to subclass your button and add a indexPath property to it     Implement a subclass for UIButton    interface NewButton UIButton  property nonatomic  strong  NSIndexPath  indexPath    Make your button of type NewButton in the XIB or in the code whereever you are initializing them   Then in the cellForRowAtIndexPath put the following line of code   button indexPath   indexPath   return cell    As usual    Now in your IBAction  - IBAction buttonClicked  id sender     NewButton  button    NewButton   sender     Now access the indexPath by buttons property       NSIndexPath  indexPath   button indexPath

To do   Vladimir  s answer is Swift   var buttonPosition   sender convertPoint CGPointZero  toView  self tableView  var indexPath   self tableView indexPathForRowAtPoint buttonPosition     Although checking for indexPath    nil gives me the finger    NSIndexPath is not a subtype of NSString

how do I know which button sent this message     processing button press for this row requires an indexPath    Pretty straightforward actually   -  void buttonPressedAction  id sender       UIButton  button    UIButton   sender      CGPoint rowButtonCenterInTableView     rowButton superview  convertPoint rowButton center toView self tableView       NSIndexPath  indexPath    self tableView indexPathForRowAtPoint rowButtonCenterInTableView       MyTableViewItem  rowItem    self itemsArray objectAtIndex indexPath row          Now you re good to go   do what the intention of the button is  but with        the context of the  row item  that the button belongs to      self performFooWithItem rowItem       Working well for me  P  if you want to adjust your target-action setup  you can include the event parameter in the method  and then use the touches of that event to resolve the coordinates of the touch  The coordinates still need to be resolved in the touch view bounds  but that may seem easier for some people

I always use tags   You need to subclass the UITableviewCell and handle the button press from there

User · Answer

Subclass the button to store the required value  maybe create a protocol  ControlWithData or something   Set the value when you add the button to the table view cell  In your touch up event  see if the sender obeys the protocol and extract the data  I normally store a reference to the actual object that is rendered on the table view cell
