Question

So I’m trying to store a cell’s indexpath when my custom cell is created in

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

I define a custom cell in class called “custom cell”, and I added a property to that class defined as such:

@property (nonatomic, strong) NSIndexPath *indexPath;

in cellForRowAtIndexPath I set the index path with customCell.indexPath = indexPath.

When I NSLog it on the very next line it returns null. Could somebody please explain why this is happening?

Edit

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
 static NSString *CellIdentifier = @"EditableCell";

EditableCell *editableCell = (EditableCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];

if (editableCell == nil) {

    editableCell = [[EditableCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}

_myTextField = [editableCell textFieldCell];

if (indexPath.section == 0){
    [_myTextField setPlaceholder:@"text"];
    [_myTextField setReturnKeyType:UIReturnKeyNext];
}
else if (indexPath.section == 1){
    [_myTextField setPlaceholder:@"text"];
    [_myTextField setReturnKeyType:UIReturnKeyNext];
}
else {
    [_myTextField setPlaceholder:@"text"];
    [_myTextField setReturnKeyType:UIReturnKeyDone];
}

_myTextField.keyboardType = UIKeyboardTypeDefault;
_myTextField.delegate = self;

return editableCell;

}

Where I call [self.tableview indexpathforcell:cell]

-(BOOL)textFieldShouldReturn:(UITextField *)textField{

if (textField.returnKeyType == UIReturnKeyNext) {

    UITableViewCell* myCell = (UITableViewCell*)textField.superview;
    EditableCell *currentCell = (EditableCell *)myCell;


       NSLog(@"INDEXPATH OF CURRENT CELL: %@",[self.tableView indexPathForCell:currentCell]);   
}     
}

You can determine the indexPath of a given cell using

-[UITableView indexPathForCell:]

If the cell needs to know it’s own indexPath:

NSIndexPath * myIndexPath = [(UITableView *)self.superview indexPathForCell:self]

But if it does, something’s not right!

Looking at your edited post I see the problem. You need:

UITableViewCell* myCell = (UITableViewCell*)textField.superview.superview

The textField is actually a subview of the cell’s contentView. This always seems a bit wrong to me, so another way to handle this is to make your custom cell the UITextFieldDelegate, and then create a delegate protocol for your cell. So within the cell you’d have:

(BOOL)textFieldShouldReturn:(UITextField *)textField {

    if (textField.returnKeyType == UIReturnKeyNext) {
        [self.delegate customCell: self textFieldDidReturn: textField];
    }     

    return NO;
}

Then in your cell’s delegate you’ll have a reference to the cell and textField
