let spinningActivity = MBProgressHUD.showHUDAddedTo(self.view, animated: true)
spinningActivity.labelText = "Loading"
spinningActivity.detailsLabelText = "Please wait"
dispatch_async(dispatch_get_main_queue()) {
self.loadDataServer()
spinningActivity.hide(true)
self.sosTableView.reloadData()
}
//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
}
