I have created a custom cell like
In this "+" sign increases the ticket count and "-" decreases it. When ticket count is 0, "-" is disabled and when ticket count is 4 "+" is disabled. It is working fine till now. The problem is Now i want to change the frame size of table when I click the "+" button of 4th row and regain the Frame size when I click "-" of 4th row. When i do so "-" functionality of other row changes randomly.PLease let me know what am i doing wrong.Thanks Here is my code

Add below Code in you button click or you can also use this method in didSelectRowForIndexPath.
[self.tableView beginUpdates];
[self.tableView endUpdates];
Use this will automatically handle tableview call Below Method.
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 300;// here you can calculate cell height according to your requirements.
}
Hope, this will help you...
