Error creating row in tableview

Error creating row in tableview.

My table view is loaded with a json.

I saw many examples here, however none were able to solve

my code

NSMutableArray *myArray = [NSMutableArray arrayWithArray:news];
        [myArray insertObject:@"teste" atIndex:0];
        NSMutableArray *path = [NSMutableArray arrayWithObject:[NSIndexPath indexPathForRow:[news count]-1 inSection:1]];
        [self.tableView insertRowsAtIndexPaths:path withRowAnimation:UITableViewRowAnimationAutomatic];
        [self.tableView endUpdates];

error displayed
