IOS adds a long-pressed gesture to the cell of tableview twice (UILongPressGestureRecognizer)

Here we add a long-pressed gesture for tableview

 

UILongPressGestureRecognizer * longPressGr = [[UILongPressGestureRecognizer alloc] initWithTarget: self action: @ selector (longPressAction :)];

LongPressGr. minimumPressDuration = 0.5f;

LongPressGr. numberOfTouchesRequired = 1;

[_ TableView addGestureRecognizer: longPressGr];

[LongPressGr release];

 

At this time, we will find that longPressAction: This method will be executed twice each time we hold down tableView and release it.

 

-(Void) longPressAction :( UILongPressGestureRecognizer *) longPress

{

If (longPress. state = UIGestureRecognizerStateBegan ){

CGPoint point = [longPress locationInView: _ tableView];

 

NSIndexPath * indexPath = [_ tableView indexPathForRowAtPoint: point]; // you can obtain the cell on which we press

 

If (indexPath! = Nil ){

NSLog (@ "% ld", indexPath. row );

}

 

}

}
