Making Simple Accordion TableView in swift? - swift

Question

Is there any way that I can make simple Accordion View in swift like the one at Calendar Event Create? I don't want to use other third party library as well as other code.
I found many answer at github and over google. But,still don't meet my requirement.
Actually I want to add two table view.
The first one is section which show City such as (New York,Los Angles,Las Vegas,etc)
When I tapped one of the city,it will show store address in tableview which mean there are many stores.
All the store and data will got from json.
The accordion view that i want to do is as simple as the one at Calendar App on iOS. But,the data that I gonna insert into two tableView (Section Header & Inner Records inside each section) which is dynamic.
Any Help? Please Guide me,Help me out.
UPDATE : Please take a look

Answer 1

The answer provided by #TechBee works fine using sections for those interested in not using sections and use cells.
The implementation of an Accordion Menu in Swift can be achieved using UITableView in a very simple way, just having two cells one for the parent cells and another for the childs cells and in every moment keep the track for the cells expanded or collapsed because it can change the indexPath.row every time a new cell is expanded or collapsed.
Using the functions insertRowsAtIndexPaths(_:withRowAnimation:) and deleteRowsAtIndexPaths(_:withRowAnimation:) always inside a block of call to tableView.beginUpdates() and tableView.endUpdates() and updating the total of items in the data source or simulating it changes we can achieve the insertion of deletion of new cells in the UITableView in a very easy way with animation included.
I've implemented myself a repository in Github with all the explained above AccordionMenu using Swift and UITableView in a easy and understandable way. It allows several cells expanded or only one at time.

Try this:
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
arrayForBool = ["0","0","0"]
sectionTitleArray = ["Pool A","Pool B","Pool C"]
var tmp1 : NSArray = ["New Zealand","Australia","Bangladesh","Sri Lanka"]
var string1 = sectionTitleArray .objectAtIndex(0) as? String
[sectionContentDict .setValue(tmp1, forKey:string1! )]
var tmp2 : NSArray = ["India","South Africa","UAE","Pakistan"]
string1 = sectionTitleArray .objectAtIndex(1) as? String
[sectionContentDict .setValue(tmp2, forKey:string1! )]
self.tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "Cell")
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return sectionTitleArray.count
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int{
if(arrayForBool .objectAtIndex(section).boolValue == true)
{
var tps = sectionTitleArray.objectAtIndex(section) as! String
var count1 = (sectionContentDict.valueForKey(tps)) as! NSArray
return count1.count
}
return 0;
}
func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return "ABC"
}
func tableView(tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 50
}
func tableView(tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
return 1
}
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
if(arrayForBool .objectAtIndex(indexPath.section).boolValue == true){
return 100
}
return 2;
}
func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let headerView = UIView(frame: CGRectMake(0, 0, tableView.frame.size.width, 40))
headerView.backgroundColor = UIColor.grayColor()
headerView.tag = section
let headerString = UILabel(frame: CGRect(x: 10, y: 10, width: tableView.frame.size.width-10, height: 30)) as UILabel
headerString.text = sectionTitleArray.objectAtIndex(section) as? String
headerView .addSubview(headerString)
let headerTapped = UITapGestureRecognizer (target: self, action:"sectionHeaderTapped:")
headerView .addGestureRecognizer(headerTapped)
return headerView
}
func sectionHeaderTapped(recognizer: UITapGestureRecognizer) {
println("Tapping working")
println(recognizer.view?.tag)
var indexPath : NSIndexPath = NSIndexPath(forRow: 0, inSection:(recognizer.view?.tag as Int!)!)
if (indexPath.row == 0) {
var collapsed = arrayForBool .objectAtIndex(indexPath.section).boolValue
collapsed = !collapsed;
arrayForBool .replaceObjectAtIndex(indexPath.section, withObject: collapsed)
//reload specific section animated
var range = NSMakeRange(indexPath.section, 1)
var sectionToReload = NSIndexSet(indexesInRange: range)
self.tableView .reloadSections(sectionToReload, withRowAnimation:UITableViewRowAnimation.Fade)
}
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{
let CellIdentifier = "Cell"
var cell :UITableViewCell
cell = self.tableView.dequeueReusableCellWithIdentifier(CellIdentifier) as! UITableViewCell
var manyCells : Bool = arrayForBool .objectAtIndex(indexPath.section).boolValue
if (!manyCells) {
// cell.textLabel.text = #"click to enlarge";
}
else{
var content = sectionContentDict .valueForKey(sectionTitleArray.objectAtIndex(indexPath.section) as! String) as! NSArray
cell.textLabel?.text = content .objectAtIndex(indexPath.row) as? String
cell.backgroundColor = UIColor .greenColor()
}
return cell
