UIGestureRecognizer in UITableViewCell - objective-c

Question

I'd like to add UIGestureRecognizer to UITableViewCell.
When I call panAction: in CustomCell class, it will work.
But I'd like to call the method in ViewController class, and in this case, it will not work.
How do I fix it to work panAction:?
- (void)viewDidLoad
{
_tableView = [[UITableView alloc]initWithFrame:self.view.frame];
_tableView.delegate = self;
_tableView.dataSource = self;
[_tableView registerClass:[CustomCell class] forCellReuseIdentifier:#"Cell"];
[self.view addSubview:_tableView];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *nibName = #"Cell";
CustomCell *cell = (CustomCell*)[tableView dequeueReusableCellWithIdentifier:nibName];
if (!cell) {
cell = (CustomCell*)[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nibName];
}
return cell;
}
- (void)setupGesture
{
UIPanGestureRecognizer* panRecognizer = [[UIPanGestureRecognizer alloc]initWithTarget:self action:#selector(panAction:)];
CustomCell* cell = (CustomCell*)[_tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0]];
[cell addGestureRecognizer:panRecognizer];
}
- (void)panAction:(UIPanGestureRecognizer *)sender
{
CGPoint location = [sender translationInView:sender.view];
NSLog(#"%f", location);
[sender setTranslation:CGPointZero inView:sender.view];
}

In the code posted above, you don't call setupGesture. This way your cell won't pick up the gestures. Also, you should just add create and add panRecognizer to the cell in tableview:cellForRowAtIndexpath: like so:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *nibName = #"Cell";
CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:nibName];
UIPanGestureRecognizer* panRecognizer = [[UIPanGestureRecognizer alloc]initWithTarget:self action:#selector(panAction:)];
[cell addGestureRecognizer:panRecognizer];
return cell;
}
