How to disable "more" cell while getting data?

I am doing some work on uitable view in that I am showing 5 records at a time if the user wants to see more records user will tap on the more and开发者_如何学C another 5 records will be fetched .

all things are working properly except if I will tap on the more simultaneously the app crashes . so what I want to so is to disable the more when first time it is tapped and enable when the data id fetched .

thanks

In tableView:didSelectRowAtIndexPath: do the following if the indexPath corresponds to the morecell:

• check if connection is already running
• if yes -> do nothing
• if no
  • morecell.selectionStyle = UITableViewCellSelectionStyleNone;
  • label.textColor = [UIColor lightGrayColor];
  • start connection

When the connection ends:

• morecell.selectionStyle = UITableViewCellSelectionStyleBlue;
• label.textColor = [UIColor blueColor];
• add rows

Assuming that the "more" is a button (control), you can disable it by setting the enabled property to NO or hide it by setting the hidden property to YES.
