(GAIUncaughtExceptionHandler.m:41): Uncaught exception: *** -[__NSArrayM objectAtIndex:]:

My code is as below:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView deselectRowAtIndexPath:indexPath animated:NO];
    if (indexPath.section == 1) {
        Episode *episode = [[Episode alloc] init];
        [episode bindProperties:[self.pager.contents objectAtIndex:indexPath.row]];
        [self.baseController performSegueWithIdentifier:SEGUE_EPISODE_VIEW sender:episode];
    }
}

I cannot solve this problem. How can I fix it? If possible, please let know. Thanks in advance.

Answer 1

You're calling objectAtIndex on the episode array with index 2, when there are only two objects in the array. Array objects are numbered starting with 0, so an array with two objects only has elements 0 and 1.

It sounds like you're not setting up your UITableView correctly. If there are only two objects in the array backing the table, there should only be two rows in the table.
