Hello All!

 

   I've been trying to get my head around the idea of a SCPropertyType that is a Selection, which will allow me to separate all the items into various sections and also have an addNewItemCell. 

 

Here is the code declaring the definition

    SCPropertyDefinition *typeDef = [entity propertyDefinitionWithName:kTypeAttribute];
    typeDef.type = SCPropertyTypeSelection;
    
    SCSelectionAttributes *selectionAttributes = [SCSelectionAttributes attributesWithItems:@[@"One", @"Two", @"Three", @"Four", @"Five"] allowMultipleSelection:NO allowNoSelection:YES];
    typeDef.attributes = selectionAttributes;

To obtain section headers i've implemented the following..

 

    typeDef.cellActions.detailTableViewModel = ^SCTableViewModel*(SCTableViewCell *cell, NSIndexPath *indexPath)
    {
        SCSelectionModel *selectionModel = [[SCSelectionModel alloc] initWithTableView:nil];
        
        selectionModel.modelActions.sectionHeaderTitleForItem = ^NSString*(SCArrayOfItemsModel *itemsModel, NSObject *item, NSUInteger itemIndex)
        {
            if (itemIndex > 2)
                return @"Section 2";
            else
                return @"Section 1";
        };
};

Which gives a detailViewController with items broken into two sections. 

 

However, i've had no luck being able to have an addNewItemCell. I attempted to assign it during the addSection modelAction block like so

        selectionModel.modelActions.didAddSection = ^(SCTableViewModel *tableModel, SCTableViewSection *section, NSUInteger sectionIndex)
        {
            if (sectionIndex == 1)
            {
                NSLog(@"Attempting to add addNewCell");
                
                SCArrayOfObjectsSection *s = (SCArrayOfObjectsSection *)section;
                s.addNewItemCell = [SCTableViewCell cellWithText:@"Add"];
                s.addNewItemCellExistsInNormalMode = YES;
                s.addNewItemCellExistsInEditingMode = YES;
            }
        };

But the various methods i've attempted never show the addNewItemCell, i've managed to add a cell which adds a new item using dispatchEventAddNewItem however the cell that dispatched the event then becomes selected.

 

If anyone has any ideas that would be great! 

 

Many Thanks

Hey Andrew

you can break items up into sections in two ways

1.. 

SCEntityDefinition *myDef = [SCEntityDefinition
  definitionWithEntityName:@"entry"
  propertyNamesString:@"Details:(title);Actions:(date,time)"];

2..

SCEntityDefinition *myDef = [SCEntityDefinition definitionWithEntityName:@"entry"
                                                            managedObjectContext:moContext
                                                           propertyNamesString:@"title;date;time"];
 
SCPropertyGroup *g1 = [SCPropertyGroup groupWithHeaderTitle:@"section 1" footerTitle:nil propertyNames:@[@"title"]];
SCPropertyGroup *g2 = [SCPropertyGroup groupWithHeaderTitle:@"section 2" footerTitle:nil propertyNames:@[@"date",@"time"]];
 
[examDef.propertyGroups addGroup:g1];
[examDef.propertyGroups addGroup:g2];

 

as for adding a add new cell

    SCArrayOfObjectsSection *objectsSection = [SCArrayOfObjectsSection
                                               sectionWithHeaderTitle:.........
    objectsSection.allowAddingItems = YES;

    SCTableViewCell *addCell = [SCTableViewCell cellWithText:NSLocalizedString(@"Add New", nil)];
    addCell.imageView.image = [UIImage imageNamed:@"greenAdd"];
    
    
    objectsSection.addNewItemCell = addCell;
    objectsSection.addNewItemCellExistsInNormalMode = YES;

Ozie, thanks for your reply! I probably didn't explain myself exactly as i intended. The actual issue is essentially trying to format the auto generated detail controller where the user can select one of the items.  If i created a simple selectionCell like this 

 

    SCTableViewSection *section = [SCTableViewSection section];
    
    SCSelectionCell *selectionCell = [SCSelectionCell cellWithText:@"Test" boundObject:nil selectedIndexPropertyName:nil items:@[@"Item 1", @"Item 2", @"Item 3"]];
    
    selectionCell.allowAddingItems = YES;
    selectionCell.addNewItemCell = [SCTableViewCell cellWithText:@"Add New Item"];
    
    [section addCell:selectionCell];
    
    [self.tableViewModel addSection:section];

The detailViewController would have all the items in a single section. 

 

Ideally what i'd like to do is have the selectable items in different sections with an extra cell that allows a newItem to be added.

 

Hopefully that makes more sense!

you would have to build your own detailviewcontroller and pass that into the cell as an action.. that way you can customise it to the way you want..

cellActions.detailViewController = ^UIViewController*(SCTableViewCell *cell, NSIndexPath *indexPath) 

 

there is no option for the scselectioncell to place items into sections, as normally a selection object is from a simple list

 

might be able to use this one too.. not sure which one is best or easier

cellActions.detailTableViewModel = ^SCTableViewModel*(SCTableViewCell *cell, NSIndexPath *indexPath)
