Question

I’m calling the numberOfRowsInSection method of the UITableView delegate inside of the heightForRowAtIndexPath but it gives me a Bad Access Error:

- (CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
    ...
    NSLog(@"number of rows in section: %i", [tableView numberOfRowsInSection:[indexPath section]]);
    ...
}

Can anybody tell me whats wrong here?

Answer 1

You need to return an actual value here. So instead of calling [tableView numberOfRowsInSection:[indexPath section]] simply do the same thing again.

In order not to duplicate your code you could create a helper method which you can call in both places, namely, your heightForRowAtIndexPath method and the numberOfRowsInSection method:

- (int) myNumberOfRowsMethod{
    // Here you would usually have some underlying model 
    return [self.myContactsOrWhateverArray count];
}
