UIPanGestureRecognizer stateEnded in a CustomCell class notifies MainViewController - ios

Question

My apps MainViewController uses a UITableView with custom UITableViewCells from CustomCell. With UIPanGestureRecognizer the user can slide a cell left or right. After the slide, the textLabel.text and slide direction are stored to static NSStrings.
The animation code is CustomCell and works fine.
How could MainViewController know or be notified when CustomCell's recognizer.state == UIGestureRecognizerStateEnded?
CustomCell
static NSString *cellAction = NULL; // textLabel.text
static NSString *slideTo = NULL; // slide direction
-(id)initWithStyle{
UIGestureRecognizer* recognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:#selector(handlePan:)];
[self addGestureRecognizer:recognizer];
}
-(void)handlePan:(UIPanGestureRecognizer *)recognizer{
}
MainViewController
-(void)viewDidLoad{
actionTable = [[UITableView alloc] initWithFrame:self.view.bounds style:UITableViewStylePlain];
[self.view addSubview:middleActionTable];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:ident forIndexPath:indexPath];
return cell;
}
After this works I plan on using the 2 static strings from CustomCell to perform a modal segue from MainViewController to AnotherViewController. I only need the 2 strings after the slide action.

Answer 1

add this code
UIGestureRecognizer* recognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:#selector(handlePan:)];
[self addGestureRecognizer:recognizer];
right after you create the cell in your MainViewController like this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:ident forIndexPath:indexPath];
//more of your existing code here
UIGestureRecognizer* recognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:#selector(handlePan:)];
[self addGestureRecognizer:recognizer];
return cell;
}
And move your handlePan: method to the MainViewController.
Unless there's a strong reason for you to have the handlePan: method in the cell class, its best to add have it in the MainViewController (if you want to avoid creating/setting a delegate or using blocks)
