Returning UITableViewCell custom cell

I have a subclass of UITableViewCell called ReminderCell.

ReminderCell has a method called backToPlaceAnimation that I wrote.

The problem is for example if I want to call backToPlaceAnimation on the first ReminderCell from RemindersVC using tableView: cellForRowAtIndexPath: it's not returning the correct object (it's UITableViewCell object and not ReminderCell at all).

How can I get the correct object?

Code:

NSIndexPath *cellIndexPath=[NSIndexPath indexPathWithIndex:0];

ReminderCell *cell=(ReminderCell*)[self tableView:self.AroundersTableView cellForRowAtIndexPath:cellIndexPath];

[cell cancelDeletion];

Crash log:

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid index path for use with UITableView. Index paths passed to table view must contain exactly two indices specifying the section and row. Please use the category on NSIndexPath in UITableView.h if possible.

cellForRowAtIndexPath: override:

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    //Creating a default cell using "cellIdentifier"(NSString)
    ReminderCell *cell=[tableView dequeueReusableCellWithIdentifier:@"Cell"];
    if (cell==nil) {
        cell=[[ReminderCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"];
    }
    //Changing "cell"'s "index" to indexPath.row
    cell.index=(int)indexPath.row; //Crashes here

    cell.textLabel.text=@"Hello";

    //Returning cell
    return cell;
}

Thank you!

You should replace [NSIndexPath indexPathWithIndex:0]; with [NSIndexPath indexPathWithIndex:0 inSection:0];

Based on the error you showed above you're not getting the cell back from the cell for row method because the index path you're creating is incorrect. Try using [NSIndexPath indexPathForRow:0 inSection:0] (Note: you will need to change the 0's to reflect the cell you want.

Your CellForRowAtIndexPath should return ReminderCell instead of UITableViewCell

So it should start with this:

-(ReminderCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

define your cell as ReminderCell

ReminderCell *cell = [self.AroundersTableView cellForRowAtIndexPath:cellIndexPath];

You are declaring cell as UITableViewCell, declare it as ReminderCell if you want it to be that type
