How to swipe tableviewcell for particular row in a section

Question

I have a custom UITableview which is diveded into sections, I have implemented UISwipeGestureRecognizer into it. When I swipe my table view cell, a UIButton appears. The problem I am now facing is when I swipe the first table view cell, another cell in successive sections also recognizes the swipe gesture. I am not able to find how to swipe a cell of particular a section without other cells of other sections getting swiped.

I just want to swipe, I don't want to delete/insert or add check marks.

UPDATE.... This is my customCell.m Tableview = customTableView

       - (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
        {
            self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
            if (self)
            {
                self.backgroundColor = [UIColor clearColor];
                self.contentView.backgroundColor = [UIColor clearColor];

                self.symptomCellImageView.contentMode=UIViewContentModeScaleToFill;


                swipeButton = [[UIButton alloc]init];
                swipeButton .frame = CGRectMake(220.0, 8.0, 30.0, 30.0);
                swipeButton .hidden = NO;

}

In my MainViewController.m

  -(void)viewDidLoad
    {        

         symptomSwipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeHandleLeft)];
         symptomSwipeLeft .numberOfTouchesRequired = 1;
         symptomSwipeLeft .direction = UISwipeGestureRecognizerDirectionLeft;
         [customTableView addGestureRecognizer:symptomSwipeLeft];
         [self addGestureRecognizer:symptomSwipeRight];

          symptomSwipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeHandleRight)];
           symptomSwipeRight.numberOfTouchesRequired = 1;
           symptomSwipeRight.direction = UISwipeGestureRecognizerDirectionRight;
           [customTableView addGestureRecognizer:symptomSwipeRight];
           [self addGestureRecognizer:symptomSwipeRight];

    }


- (void)swipeHandleLeft:(UISwipeGestureRecognizer *)aSwipeGestureRecognizer
{
     CGPoint location = [aSwipeGestureRecognizer locationInView:customTableView ];
     NSIndexPath * indexPath = [customTableView indexPathForRowAtPoint:location];

     if(indexPath)
{
        UITableViewCell * cell = (UITableViewCell *)[customTableView cellForRowAtIndexPath:indexPath];
       [cell.swipeButton addTarget:self action:@selector(secondPageButton:) forControlEvents:UIControlEventTouchUpInside];

              }
}



- (void)swipeHandleRight:(UISwipeGestureRecognizer *)aSwipeGestureRecognizer
 {
     CGPoint location = [aSwipeGestureRecognizer locationInView:customTableView ];
     NSIndexPath * indexPath = [customTableViewindexPathForRowAtPoint:location];

     if(indexPath)
{
       UITableViewCell * cell = (UITableViewCell *)[customTableView cellForRowAtIndexPath:indexPath];
        [cell.swipeButton addTarget:self action:@selector(secondPageButton:) forControlEvents:UIControlEventTouchUpInside];
              }
 }

Answer 1

Try:

- (void)handleSwipe:(UISwipeGestureRecognizer *)aSwipeGestureRecognizer; {
  CGPoint location = [aSwipeGestureRecognizer locationInView:_tableView];
  NSIndexPath * indexPath = [_tableView indexPathForRowAtPoint:location];

  if(indexPath){
    UITableViewCell * cell = (UITableViewCell *)[_tableView cellForRowAtIndexPath:indexPath];
    [cell whateverMethodYouWant];
  }
}

As a side note, the reason you are getting calls to multiple cells is because the row is not unique enough. There is a row = 0 in all of you sections. Therefore, if you want each cell to have a unique number attached to its .tag property, you would need to know the largest number of rows in any section (call it largestNumberOfRows), and then compute:

cell.swipeButton.tag = (indexPath.section * largestNumberOfRows) + indexPath.row;

Hope that helps!

EDIT:

To use the above method, in your viewDidLoad; method, add the following code:

UISwipeGestureRecognizer * recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe:)];
[recognizer setDirection:(UISwipeGestureRecognizerDirectionRight | UISwipeGestureRecognizerDirectionLeft)];
[_tableView addGestureRecognizer:recognizer];

EDIT 2

Looking at your code, you have put your gesture recognizers in the wrong file. Here is the setup:

In your MainViewController.m file:

- (void)viewDidLoad; {
  [super viewDidLoad];
  UISwipeGestureRecognizer * recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe:)];
  [recognizer setDirection:(UISwipeGestureRecognizerDirectionRight | UISwipeGestureRecognizerDirectionLeft)];
  [_tableView addGestureRecognizer:recognizer];
}

- (void)handleSwipe:(UISwipeGestureRecognizer *)aSwipeGestureRecognizer; {
  CGPoint location = [aSwipeGestureRecognizer locationInView:_tableView];
  NSIndexPath * indexPath = [_tableView indexPathForRowAtPoint:location];

  if(indexPath){
    UITableViewCell * cell = (UITableViewCell *)[_tableView cellForRowAtIndexPath:indexPath];

    if(aSwipeGestureRecognizer.direction == UISwipeGestureRecognizerDirectionRight){
      [cell symptomCellSwipeRight];
    }
    else if(aSwipeGestureRecognizer.direction == UISwipeGestureRecognizerDirectionLeft){
      [cell symptomCellSwipeLeft];
    }
  }
}

- (UITableViewCell *)cellForRowAtIndexPath:(NSIndexPath *)indexPath; {
  // Initial your cell. Then add:
  [cell.swipeButton addTarget:self action:@selector(secondPageButton:) forControlEvents:UIControlEventTouchUpInside];
}

In your PPsymptomTableCell.m file:

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier; {
  if((self = [super initWithStyle:style reuseIdentifier:reuseIdentifier])){
    self.backgroundColor = [UIColor clearColor];
    self.contentView.backgroundColor = [UIColor clearColor];

    self.symptomCellImageView.contentMode=UIViewContentModeScaleToFill;

    // SHARE ON FACEBOOK BUTTON //

    shareFacebookButton = [[UIButton alloc]init];
    shareFacebookButton.frame = CGRectMake(220.0, 8.0, 30.0, 30.0);
    shareFacebookButton.hidden = NO;

    // DISPLAY NOTIFICATION IMAGE //

    selectedCellImageDisplay = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"selectedSymptomImage.png"]];
    selectedCellImageDisplay.frame = CGRectMake(240.0, 8.0, 30.0, 30.0);

    // SYMPTOM NAME //

    symptomCellLabel=[[UILabel alloc]initWithFrame:CGRectMake(15.0,0.0 ,280.0,40.0)];
    symptomCellLabel.font=[UIFont fontWithName:@"Rockwell" size:17];
    symptomCellLabel.textColor=[UIColor blackColor];
    symptomCellLabel.backgroundColor=[UIColor clearColor];

    [self.contentView addSubview:symptomCellLabel];
    [self.contentView addSubview:selectedCellImageDisplay];
    [self.contentView addSubview:shareFacebookButton];
  }
  return self;
}

- (void)symptomCellSwipeLeft; {
  [UIView beginAnimations:@"HideView" context:nil];
  symptomCellLabel.frame = CGRectMake(-183.0, 0.0, 280.0, 40.0);
  selectedCellImageDisplay.frame = CGRectMake(-340.0, 8.0, 30.0, 30.0);
  shareFacebookButton.frame = CGRectMake(120.0, 8.0, 80.0, 30.0);
  shareFacebookButton.hidden = NO;
  shareFacebookButton.backgroundColor = [UIColor redColor];

  [UIView setAnimationDuration:0.3f];
  [UIView commitAnimations];
}


- (void)symptomCellSwipeRight; {
  [UIView beginAnimations:@"HideView" context:nil];
  symptomCellLabel.frame = CGRectMake(15.0,0.0 ,280.0,40.0);
  selectedCellImageDisplay.frame = CGRectMake(240.0, 8.0, 30.0, 30.0);
  shareFacebookButton.frame = CGRectMake(220.0, 8.0, 30.0, 30.0);
  shareFacebookButton.hidden = YES;

  [UIView setAnimationDuration:0.3f];
  [UIView commitAnimations];
}

This should get everything working nicely.
