I'm trying to do the same thing but don't really know where you can access the cell object directly to set the security.
This is what I have so far:
// Create Task class definition
SCClassDefinition *userClassDef = [SCClassDefinition definitionWithClass:[User class]
withPropertyNames:[NSArray arrayWithObjects:@"username", @"password", nil]];
SCPropertyDefinition *usernamePropertyDef = [userClassDef propertyDefinitionWithName:@"username"];
usernamePropertyDef.required = YES;
usernamePropertyDef.type = SCPropertyTypeTextField;
SCPropertyDefinition *passwordPropertyDef = [userClassDef propertyDefinitionWithName:@"password"];
passwordPropertyDef.required = YES;
passwordPropertyDef.type = SCPropertyTypeTextField;
// Initialize tableModel
tableModel = [[SCTableViewModel alloc] initWithTableView:self.tableView withViewController:self];
SCObjectSection *userSection = [SCObjectSection sectionWithHeaderTitle:@"login" withBoundObject:self.user withClassDefinition:userClassDef];
userSection.headerTitle = nil;
userSection.footerTitle = nil;
userSection.headerView = [[UIView alloc] initWithFrame:CGRectZero];
userSection.footerView = [[UIView alloc] initWithFrame:CGRectZero];
tableView.backgroundColor = [UIColor clearColor];
tableView.backgroundView = [[UIView alloc] initWithFrame:CGRectZero];
[tableModel addSection:userSection];
