Here's the code!

- (void)celllongpressed:(UILongPressGestureRecognizer *)gesture
{

if (gesture.state == UIGestureRecognizerStateBegan)
{
    cell = (ActivityFeedCell *)[gesture view];
}
if (gesture.state == UIGestureRecognizerStateChanged)
{
    cell = (ActivityFeedCell *)[gesture view];
    logGes_view=[[UIView alloc]initWithFrame:CGRectMake(5, 0,self.view.frame.size.width-10,self.view.frame.size.height)];
    image=[[UIImageView alloc]initWithFrame:CGRectMake(0, 80,self.view.frame.size.width, self.view.frame.size.height-80)];
    image.image=cell.updated_imgView.image;
    UILabel *name_label=[[UILabel alloc]initWithFrame:CGRectMake(10, 15, 150, 30)];
    //city_label.backgroundColor=[UIColor yellowColor];
    name_label.text=lgGesNamelbl;
    UILabel *city_label=[[UILabel alloc]initWithFrame:CGRectMake(10, 50, 180, 30)];
    //city_label.backgroundColor=[UIColor yellowColor];
    city_label.text=lgGesCitylbl;
    [logGes_view addSubview:city_label];
      [logGes_view addSubview:name_label];
    [logGes_view addSubview:image];
    logGes_view.backgroundColor=[UIColor whiteColor];
    [self.view addSubview:logGes_view];
}
if (gesture.state == UIGestureRecognizerStateEnded)
{
   // cell = (ActivityFeedCell *)[gesture view];
    [logGes_view removeFromSuperview];
}
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UILongPressGestureRecognizer *gesture1 = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(celllongpressed:)];
[gesture1 setDelegate:self];
[gesture1 setMinimumPressDuration:1.0];
[ cell setUserInteractionEnabled:YES];
[cell addGestureRecognizer:gesture1];
}

Show the resulting output and code which you have write for the same. — Bhadresh Mulsaniya, Jul 27 '16 at 10:55
clipSubviews may be checked on the CustomCell! Try to disable that either is cellForRowAtIndexPath() or in the Interface Builder if using prototype cells! — Ariel, Jul 27 '16 at 11:03
@simerkaur You should not post codes and images in the comment section. Post it in the Questions for more detail please! — Ariel, Jul 27 '16 at 11:05
in method of gesture if (gesture.state == UIGestureRecognizerStateBegan) { UITableViewCell *cell = (UITableViewCell *)[gesture view]; } if (gesture.state == UIGestureRecognizerStateChanged) { cell = (UITableViewCell *)[gesture view]; cell.updated_imgView.frame=CGRectMake(0, 0, tableview.frame.size.width, tableview.frame.size.height); } if (gesture.state == UIGestureRecognizerStateEnded) { cell = (UITableViewCell *)[gesture view]; cell.updated_imgView.frame=CGRectMake(30, 0, 300 , 300); } — simer kaur, Jul 27 '16 at 11:06

        UILongPressGestureRecognizer *reconizer=[[UILongPressGestureRecognizer alloc]initWithTarget:self action:@selector(handleLongPress:)];
                   [reconizer setMinimumPressDuration:1.0];
                 [cell addGestureRecognizer:reconizer];


-(void)handleLongPress:(UILongPressGestureRecognizer*)reconizer

{
    UITableViewCell *cell = (UITableViewCell *)[gesture view];
    NSIndexPath *indexPath = [tableview indexPathForCell:cell];
    NSString *s = [NSString stringWithFormat: @"row=%1ld",(long)indexPath.row];
    [self setTitle: s];

@simerkaur you try to change the image view frame in UIGestureRecognizerStateEnded. – Saurabh Jain Jul 27 '16 at 12:44
@simerkaur I Have tried your problem my side and found that when you long press on a image.. it size change according the view size but it show only cell content view.. so my advise is you show the image on a image which size equal to the view size. – Saurabh Jain Jul 27 '16 at 13:00
image is show on table view cell but there is a problem of size – simer kaur Jul 27 '16 at 13:12
@simerkaur what's problem? – Saurabh Jain Jul 27 '16 at 13:13
i want to set the size of image according to main view means screen size but takes the size of cell ... – simer kaur Jul 27 '16 at 13:14
@simerkaur I already said you take a image view on the table view and before long pressing you set is hidden .. after long press when you take the response then you set the image on Image View and set the property hidden NO. – Saurabh Jain Jul 27 '16 at 13:18
@simerkaur Got my answer? – Saurabh Jain Jul 27 '16 at 13:26
@simerkaur You should hidden the image view rather than remove. – Saurabh Jain Jul 29 '16 at 05:11
i have also used hidden and remove property , but there is no effect ,sir – simer kaur Jul 30 '16 at 10:53
Can you please send the screen shot of your issue? – Saurabh Jain Jul 30 '16 at 11:23

[cell addGestureRecognizer:gesture1]

replace with below line

[ cell.yourimageview setUserInteractionEnabled:YES];  // This enable user interaction on the image view. Required!!


[cell.yourimageview addGestureRecognizer:gesture1];  //yourimageview is your image outlet

Try it: Cell is superView of imageView so on size changing it will not cross cell frame add it to mainView after resize.
