Passing a value on a IBAction button method in a UITableview Row

Question

I have a value called member id and I want to send it to another view controller, If I place the following in didSelectRowAtIndexPath, The value passes to the variable "member".

int memberIndex = [indexPath indexAtPosition: [indexPath length] - 1];
    member = [[tableDataSource2 objectAtIndex: memberIndex] objectForKey:@"Memberid"];

If it is placed in the cellForRow, of course it rewrites with every row created. I have a button in each row that launches a viewController, I want the button action to grab the rows "member" and pass it to the new controller. Is there a "didSelectButton at index path method" or a way to grab that on the fly?

any Ideas would be great. It's the first time I'm adding a button to a UiTableview.

Thanks

Why not use the accessory view? It is a built-in button that you can skin with any image you want to give the UI any kind of feel that is required. Then add this to the table's delegate:

accessoryButtonTappedForRowWithIndexPath: (NSIndexPath *) indexPath{ ... }

You will then be able to call your method on your table data source and launch your secondary view.

How is this supposed to work? The documentation on this method clearly states "This method is not called when an accessory view is set for the row at indexPath. " Indeed, in my case the method does not get called if I set a custom button as the accessory view. – Katlu Oct 17 '12 at 14:54

Just play with "tag".

Each UIView has an attribute tag (int).

in the cellForRowAtIndexPath :

//create yourButton and then
yourButton.tag = memberIndex;

and when you are using an IBAction just get the sender :

- (IBAction) didSelectButton:(id)sender
{
int memberIndex = ((UIButton *)sender).tag;
//
}

tips : to get the sender when you are setting the action property of your button don't forget the ":"

E.G

action = @selector(didSelectButton:);
