//loadDataSos()
// Uncomment the following line to preserve selection between presentations
// self.clearsSelectionOnViewWillAppear = false
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem()
var refreshControl = UIRefreshControl()
refreshControl.addTarget(self, action: Selector("refreshData"), forControlEvents: UIControlEvents.ValueChanged)
self.refreshControl = refreshControl
}
Refresh func
func refreshData(){
dispatch_async(dispatch_get_main_queue()) {
self.loadDataServer()
self.sosTableView.reloadData()
}
refreshControl?.endRefreshing()
}
load server func
func loadDataServer(){
do {
let data = NSData(contentsOfURL: NSURL(string: "http://xxxx/scripts/xxx.php")!)
let jsonResult = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableContainers)
//let NumberOfPersons = jsonResult.count
// **LOOP THROUGH THE JSON ARRAY**
for anItem in jsonResult as! [Dictionary<String, AnyObject>] {
let userId = anItem["userId"] as! String
let userName = anItem["firstName"] as! String
let userAddress = anItem["address"] as! String
let userDate = anItem["date"] as! String
let userLocation = anItem["location"] as! String
var userEvent = anItem["event"] as? String
let sosId = anItem["sosId"] as! String
// do something with personName and personID
let imageUrl = NSURL(string:"http://xxx")
let imageData = NSData(contentsOfURL: imageUrl!)
if userEvent == nil{
userEvent = "Need Help"
}else if userEvent! == "1" {
userEvent! = "Thief"
}
else if userEvent! == "2" {
userEvent! = "Fire"
}
else{
userEvent! = "Healthy Issue"
}
//print(personName)
if imageData == nil{
let photo1 = UIImage(named: "defaultPhoto")!
let data1 = dataSos(userId: userId, name: userName, location: userLocation, address: userAddress, event: userEvent!, date: userDate, photo: photo1, sosId: sosId)
self.datas += [data1]
}
else{
let photo1 = UIImage(data: imageData!)
//let photo1 = UIImage(named: "defaultPhoto")
let data1 = dataSos(userId: userId, name: userName, location: userLocation, address: userAddress, event: userEvent!, date: userDate, photo: photo1, sosId: sosId)
self.datas += [data1]
}
}
} catch let error as NSError {
print(error)
}
// }
}
Update: table view data source
// MARK: - Table view data source
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// warning Incomplete implementation, return the number of rows
return datas.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cellIdentifier = "cell"
let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! MainTableViewCell
// Configure the cell...
let data0 = datas[indexPath.row]
cell.nameLabel.text = data0.name
cell.locationLabel.text = data0.location
cell.addressTextView.text = data0.address
cell.eventLabel.text = data0.event
cell.dateLabel.text = data0.date
cell.photoLabel.image = data0.photo
self.roundingUIView(cell.photoLabel, cornerRadiusParam: 35)
return cell
}

Ok, I just understood that you're inheriting for UITableViewController, therefor you already have tableView property inherited from it. The table view from this property has already set delegate and dataSource to your controller, but not for your custom sosTableView. You should replace your custom sosTableView with inherited tableView property and then everything gonna work as you're expecting.
