Here are clarified instruction combining Dawn Song's answer and Marmor's answer.

Drag a long Press Gesture Recognizer and drop it into your Table Cell. It will jump to the bottom of the list on the left.

Then connect the gesture recognizer the same way you would connect a button.

Add the code from Marmor in the the action handler

- (IBAction)handleLongPress:(UILongPressGestureRecognizer *)sender {
if (sender.state == UIGestureRecognizerStateBegan) {

    CGPoint p = [sender locationInView:self.tableView];

    NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:p];
    if (indexPath == nil) {
        NSLog(@"long press on table view but not on a row");
    } else {
        UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
        if (cell.isHighlighted) {
            NSLog(@"long press on table view at section %d row %d", indexPath.section, indexPath.row);
        }
    }
}

}

Answer in Swift 5  Continuation of Ricky s answer in Swift      Add the UIGestureRecognizerDelegate to your ViewController    override func viewDidLoad         super viewDidLoad          Long Press     let longPressGesture   UILongPressGestureRecognizer target  self  action   selector handleLongPress       longPressGesture minimumPressDuration   0 5     self tableView addGestureRecognizer longPressGesture          And the function     objc func handleLongPress longPressGesture  UILongPressGestureRecognizer        let p   longPressGesture location in  self tableView      let indexPath   self tableView indexPathForRow at  p      if indexPath    nil           print  Long press on table view  not row          else if longPressGesture state    UIGestureRecognizer State began           print  Long press on row  at   indexPath  row

First add the long press gesture recognizer to the table view   UILongPressGestureRecognizer  lpgr     UILongPressGestureRecognizer alloc     initWithTarget self action  selector handleLongPress     lpgr minimumPressDuration   2 0    seconds lpgr delegate   self   self myTableView addGestureRecognizer lpgr    lpgr release     Then in the gesture handler   - void handleLongPress  UILongPressGestureRecognizer   gestureRecognizer       CGPoint p    gestureRecognizer locationInView self myTableView        NSIndexPath  indexPath    self myTableView indexPathForRowAtPoint p       if  indexPath    nil            NSLog   long press on table view but not on a row          else if  gestureRecognizer state    UIGestureRecognizerStateBegan            NSLog   long press on table view at row  ld   indexPath row         else           NSLog   gestureRecognizer state    ld   gestureRecognizer state             You have to be careful with this so that it doesn t interfere with the user s normal tapping of the cell and also note that handleLongPress may fire multiple times  this will be due to the gesture recognizer state changes

Use the UITouch timestamp property in touchesBegan to launch a timer or stop it when touchesEnded got fired

Looks to be more efficient to add the recognizer directly to the cell as shown here   Tap amp Hold for TableView Cells  Then and Now   scroll to the example at the bottom

Just add UILongPressGestureRecognizer to the given prototype cell in storyboard  then pull the gesture to the viewController s  m file to create an action method  I made it as I said

I put together a little category on UITableView based on Anna Karenina s excellent answer   Like this you ll have a convenient delegate method like you re used to when dealing with regular table views  Check it out       UITableView LongPress h   import  lt UIKit UIKit h gt    protocol UITableViewDelegateLongPress    interface UITableView  LongPress   lt UIGestureRecognizerDelegate gt   property nonatomic assign    id  lt UITableViewDelegateLongPress gt    delegate  -  void addLongPressRecognizer   end    protocol UITableViewDelegateLongPress  lt UITableViewDelegate gt  -  void tableView  UITableView   tableView didRecognizeLongPressOnRowAtIndexPath  NSIndexPath   indexPath   end        UITableView LongPress m   import  UITableView LongPress h    implementation UITableView  LongPress   dynamic delegate   -  void addLongPressRecognizer       UILongPressGestureRecognizer  lpgr     UILongPressGestureRecognizer alloc                                            initWithTarget self action  selector handleLongPress         lpgr minimumPressDuration   1 2    seconds     lpgr delegate   self       self addGestureRecognizer lpgr       -  void handleLongPress  UILongPressGestureRecognizer   gestureRecognizer       CGPoint p    gestureRecognizer locationInView self        NSIndexPath  indexPath    self indexPathForRowAtPoint p       if  indexPath    nil            NSLog   long press on table view but not on a row              else           if  gestureRecognizer state    UIGestureRecognizerStateBegan                   I am not sure why I need to cast here  But it seems to be alright                id lt UITableViewDelegateLongPress gt  self delegate tableView self didRecognizeLongPressOnRowAtIndexPath indexPath                       If you want to use this in a UITableViewController  you probably need to subclass and conform to the new protocol   It works great for me  hope it helps others

I ve used Anna-Karenina s answer  and it works almost great with a very serious bug   If you re using sections  long-pressing the section title will give you a wrong result of pressing the first row on that section  I ve added a fixed version below  including the filtering of dummy calls based on the gesture state  per Anna-Karenina suggestion    -  IBAction handleLongPress  UILongPressGestureRecognizer   gestureRecognizer       if  gestureRecognizer state    UIGestureRecognizerStateBegan             CGPoint p    gestureRecognizer locationInView self tableView            NSIndexPath  indexPath    self tableView indexPathForRowAtPoint p           if  indexPath    nil                NSLog   long press on table view but not on a row              else               UITableViewCell  cell    self tableView cellForRowAtIndexPath indexPath               if  cell isHighlighted                    NSLog   long press on table view at section  d row  d   indexPath section  indexPath row
