Terminating app due to uncaught exception 'NSRangeException', reason:-[__NSArrayM objectAtIndex:]: index 0 beyond bounds for empty array'

Question

I have been trying to figure out why this error is happening for a while I put the tableview in view controller. Set the tableview delegate and datasource to view controller. I have implemented the delegate and datasource protocols.

I have done the same scene in fresh project almost 4 times, It worked fine. When I am trying to implement this scene in my current projects I see this error.

If I remove setting the delegate of table view then everything goes fine.

It is happening after returning cell.

What could be the reason? I am unable to figure it.I am using no arrays too.

please show the full code,screenshot is not too helpful, paste all the code involved. also why not using array — meda, Oct 26 '15 at 23:33
Update your question with relevant code (pasted as text). Point out where the error actually happens. — rmaddy, Oct 26 '15 at 23:41
The error is most likely due to your datasource and you are not showing that. — Daniel Zhang, Oct 26 '15 at 23:50
I already used this methods in other tableview. //-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath; - (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath So I had to rewrite it in current scene.

Try adding an all-exception breakpoint (Add Exception Breakpoint) to debug where the exception occures. Maybe it is not even in that viewcontroller.

1) Use Exception Break points...As per the above answer make sure if the delegate methods were set in previous scenes of the project.

I used all the below methods:

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;
-(void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath;
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath;
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath;
