Map Object into 2D Array Swift for TableView Sections - ios

Question

I could not figure out a better way of doing this. I am mapping all the properties of the Student Object into a 2D Array. So my TV has sections.
I cannot use a Static Tableview either, if so this problem would not exist.
So my code in the TVC
let currentUser = PFUser.currentUser()! as! MyUser
var membershipSection:[[String:String]]!
var detailsSection:[[String:String]]!
var emergancySection:[[String:String]]!
var medicalSection:[[String:String]]!
var titlesForSection = ["MEMBERSHIP", "DETAILS", "EMERGANCY CONTACT", "MEDICAL HISTORY"]
var combo = [[[String:String]]]() // Data Source for TableView
// The following is called from ViewDidLoad
func loadDisplayDataSource() {
combo.removeAll(keepCapacity: true)
var idString = "Awaiting ID Generation"
if student.objectId != nil {
idString = student.objectId!
}
membershipSection = [["Sessions":student.sessionsRemaining], ["Details":""], ["ID":idString]]
detailsSection = [["First Name":student.firstName], ["Last Name":student.lastName], ["DOB":""], ["Address":""], ["Phone":""], ["Email":student.email], ["Occupation":""]]
emergancySection = [["Name":""], ["Phone":""]]
medicalSection = [["Recent Surgery":""], ["Hypertension":""], ["Diabetes":""], ["Caradic":""], ["Epilesy":""], ["Syncope":""], ["Medications":""], ["Medical Details":""], ["Other Injuries":""]]
combo.append(membershipSection)
combo.append(detailsSection)
combo.append(emergancySection)
combo.append(medicalSection)
self.tableView.beginUpdates()
var range = NSMakeRange(0, self.numberOfSectionsInTableView(self.tableView))
var sections = NSIndexSet(indexesInRange: range)
self.tableView.deleteSections(sections, withRowAnimation: UITableViewRowAnimation.None)
self.tableView.insertSections(sections, withRowAnimation: UITableViewRowAnimation.Fade)
self.tableView.endUpdates()
}
Is there a better way to map a object's data into sections ? The way I'm doing it works, but is a little confusing. If i could use a static view this would be easier, but I cannot as using a drop in TV within a Normal VC and you cannot use static TV in these. Which is annoying! Is there a cleaner way?
Can I make this more SWIFTY - A better way to create my combo data source.
Thanks for any advice.
My end result - which is working looks like this - A TVC with sections.

Answer 1

I'm not entirely sure what you're asking. What is 'combo' used for?
If you want to just package up your data in a cleaner fashion, structs in Swift are nice for this. Something like:
struct EmergencySection{
var name: String!
var phone: String!
}
//then to instantiate in loadDisplayDataSource
var emergencySection = EmergencySection(name: "", phone: "")
combo.append(emergencySection)

Try using RETableViewManager, it's pretty awesome for such tasks. Well, it's fully Objective-C, but at least you could have a quick look of it.

How about this?
import UIKit
class
ViewController: UITableViewController {
var combo = [ [ String: AnyObject? ] ]()
let titlesForSection = ["MEMBERSHIP", "DETAILS", "EMERGANCY CONTACT", "MEDICAL HISTORY"]
override func
viewDidLoad() {
super.viewDidLoad()
// Something about studen data
combo = [
[ "Sessions":"student.sessionsRemaining", "Details":"", "ID":"idString" ]
, [ "First Name":"student.firstName", "Last Name":"student.lastName", "DOB":"", "Address":"", "Phone":"", "Email":"student.email", "Occupation":"" ]
, [ "Name":"", "Phone":"" ]
, [ "Recent Surgery":"", "Hypertension":"", "Diabetes":"", "Caradic":"", "Epilesy":"", "Syncope":"", "Medications":"", "Medical Details":"", "Other Injuries":"" ]
]
}
override func
numberOfSectionsInTableView(tableView: UITableView ) -> Int {
return combo.count
}
override func
tableView(tableView: UITableView, numberOfRowsInSection section: Int ) -> Int {
return combo[ section ].count
}
override func
tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return titlesForSection[ section ]
}
override func tableView( tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath ) -> UITableViewCell {
let v = tableView.dequeueReusableCellWithIdentifier( "SomeIdentifier" ) as! UITableViewCell
let w = combo[ indexPath.section ]
let wKey = Array( w.keys )[ indexPath.row ]
v.textLabel!.text = wKey
v.detailTextLabel!.text = w[ wKey ] as? String
return v
}
}

Here is how I am doing it, a bit cleaner
private struct Details {
static let title = "DETAILS"
static let firstName = (key:"First Name", index:0)
static let lastName = (key:"Last Name", index:1)
static let dob = (key:"DOB", index:2)
static let address = (key:"Address", index:3)
static let phone = (key:"Phone", index:4)
static let email = (key:"Email", index:5)
static let occupation = (key:"Occupation", index:6)
static func splitIntoDictionaries(student: Student) -> [[String:String]] {
return [
[firstName.key:student.firstName], // 0
[lastName.key:student.lastName], // 1
[dob.key:""],
[address.key:""],
[phone.key:""],
[email.key:student.email],
[occupation.key:""]
]
}
}

You can use a UITableViewController with static cells in a normal UIViewController by adding it as a child view controller.
parentVC.addChildViewController(childVC)
childVC.view.frame = parentVC.view.bounds
parentVC.view.addSubview(childVC.view)
childVC.didMoveToParentViewController(parentVC)
