I am in a detail view and I have added a UI button into the top most cell which is not bound to any data

 

If I link this button to the relevant view controller in IB for a "show" segue,  the new view controller is pushed onto the stack and appears nicely.

 

Of course, I want to be able to prepare an object on the new view controller (a subclassed Parse PFObject in my case) so i need to intercept that call. Not surprisingly, prepareForSegue is not called so I'm at a loss where I can intercept and assign my object on the new view controller to the one on the current detail view controller.

 

I'm like everyone else: the more I can do in IB, the better but where would I put the code I need to make the simple assignment?

Found a way to get it to start to work.

1) Generate the detail section in IB

2) Subclassed SCTableViewController and change class of detail vc in IB

3) Implemented prepareForSegue

 

So how do I access the current object from my detail view controller?

Hi sumowesley,

 

You can get the current object by accessing the button's parent cell as follows:

 

    UIView *parent = [myButton superview];
    while (parent && ![parent isKindOfClass:[SCTableViewCell class]]) 
    {
        parent = parent.superview;
    }

    SCTableViewCell *cell = (SCTableViewCell *)parent;
    NSObject *currentObject = cell.boundObject;

 

Hope this helps.

Hi Tarek,

 

Thanks for that - I should be able to give it a try tonight.

That works, thank you.

 

Does the SCTableViewController not have a bound Object if it is generated as a detail view?

Hi sumowesley,

 

The SCTableViewControllers tableViewModel has a masterBoundObject which might be what you are looking for.

That's the fella. Thank you.
