{

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];
}

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


-(void)handleLongPress:(UILongPressGestureRecognizer*)reconizer
{
if (gesture.state == UIGestureRecognizerStateBegan)
{
    UITableViewCell *cell = (UITableViewCell *)[gesture view];
    NSIndexPath *indexPath = [tableview indexPathForCell:cell];
    NSString *s = [NSString stringWithFormat: @"row=%1ld",(long)indexPath.row];
    [self setTitle: s];
}
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(0, 0, 100, 100);
}

}

-(BOOL)canBecomeFirstResponder
{
    return YES;
}

Answer 2

[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

尝试一下：单元格是imageView的超级视图，因此在更改大小时不会改变单元格的大小，而是在调整大小后将其添加到mainView中。
