Question

I have custom cell having switch in few cells at right side. what I want is to store value of specific cell on switch change event. Table view has number sections so I can\'

Answer 1

In your custom cell add properties which help you identify the information the cell represents. Index path, indexes for your data model etc...

Then add a block property to the cell which you can call to tell a UITableView or any other piece of code when a cell switch changes. e.g.

@property (nonatomic,copy) void (^onSwitchChange)(UITableViewCell *cell);

Inside your custom cell code, add an action handler for the UISwitch. When it fires, call self.onSwitchChange(self) which will notify the code which registered an onSwitchChange block that a switch has changed and on which cell.

In your table view when you create the cell, set the onSwitchChange block as follows:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath (NSIndexPath *)indexPath
{
  

  YourUITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:yourCellIdentifier forIndexPath:indexPath];
  cell.onSwitchChange=^(UITableViewCell *cellAffected){
    // Add code to deal with the swicth switch using properties of cellAffected
    ... Your handler code here ...
  }];

  
}

This lets you handle all the changes in the table view controller. Hope this helps.
