TableViewCellDelegate isnt being called - ios

Question

I am trying to add item to basket in this files. I have custom table cell and linked it with IBOutlets in storyboard. Somehow debugger reaches the delegate method inside deletegating object, but doesnt go further to TableVC, where this method is conformed, and no logs are seen.

Why my protocol isn being called?

Answer 1

You have to set your view controller as delegate:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *identifier = #"seatCell";
SeatTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier forIndexPath:indexPath];
cell.delegate = self;
....
}

Answer 2

AlexInspired,
The only statement missing is in cellForRowAtIndexPath :)
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *identifier = #"seatCell";
//todo try fix bug with dequing indexes
SeatTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier forIndexPath:indexPath];
Seat *cur = [_seats objectAtIndex:indexPath.row];
_currentSeat = cur;
cell.rowLabel.text = cur.rowNum;
cell.seatLabel.text = cur.seatNum;
cell.delegate = self;
....
return cell;
}

Answer 3

You didn't set delegate for tableview cell.
Set delegate and enjoy :) your problem is solved.
cell.delegate = self

Answer 4

you forget to set delegate to self. so in cellForRowAtIndexPath set delegate to self like,
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *identifier = #"seatCell";
//todo try fix bug with dequing indexes
SeatTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier forIndexPath:indexPath];
cell.delegate = self;
}
by this you are assigning current class object to cell class so you can able to call current class method from cell class.
:)

Answer 5

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *identifier = #"seatCell";
//todo try fix bug with dequing indexes
SeatTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier forIndexPath:indexPath];
cell.delegate=self;
.

Answer 6

write following code in CellforRowAtIndexPath method it will help for you
NSString *cellDdentifier = #"seatCell";
SeatTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier forIndexPath:indexPath];
cell.delegate = self
