Hey Bala,

you can do that a few different ways and at different levels of the tableview hierarchy including section and cell.


If you add that capability at the cell level, you would be adding a SCPropertyDefinition to your class definition (or entity definition if your using core data) and then setting its attributes to be a selection cell.


Kind of like this:


SCPropertyDefinition *pd = [SCPropertyDefinition definitionWithName:name title:title type:SCPropertyTypeSelection];


pd.attributes = [SCSelectionAttributes attributesWithItems:choices allowMultipleSelection:allowMultiple allowNoSelection:allowMultiple autoDismissDetailView:calculatedAutoDismiss hideDetailViewNavigationBar:NO];



Or you could swap out your existing section (probably a SCArrayOfObjectsSection) with an SCObjectSelectionSection.  Just initialize it and add it to the tableview model like any other section.  It will allow you to select one or more object and store those objects in a NSSet you can access as: [section].selectedItemsIndexes.  



SCObjectSelectionSection *section = [SCObjectSelectionSection sectionWithHeaderTitle:@"Select Items" items:self.items itemsDefinition:serviceBoardDef];


Add to Tableview:

[self.tableViewModel addSection:section];


Process inside of done button method or inside of one of the cell actions like didSelect:

SCObjectSelectionSection *section = (id)[self.tableViewModel sectionAtIndex:0];

if (section.selectedItemsIndexes.count > 0) {  //do something  }


It's pretty straight forward once you get the hang of it.  It's also covered in the STV ebook.

best of luck,
