Save to parse manually after data has been queried - ios

Question

I am using Parse pinInBackground feature to pin data (image, text, date, coordinates) in the background and that data is queried every time the app is opened.The app is used to log a photo and the location and coordinates.So every entry you make is queried and displays in a tableview (only the count of entries yet).
I want to be able to let the user manually sink with Parse.com and not use the saveEventually feature.
Meaning I want a button and when pressed the queried data must sink with Parse and the be in pinned.
Here is how my data is pinned
#IBAction func submitButton(sender: AnyObject) {
locationLogs["title"] = log.title
locationLogs["description"] = log.descriptionOf
println("log = \(log.title)")
println("log = \(log.descriptionOf)")
locationLogs.pinInBackgroundWithBlock { (success: Bool, error: NSError?) -> Void in
if (success) {
}else{
println("error = \(error)")
}}
func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
let location:CLLocationCoordinate2D = manager.location.coordinate
let altitude: CLLocationDistance = manager.location.altitude
println("new long= \(location.longitude)")
println("new lat= \(location.latitude)")
println("new altitude= \(altitude)")
println("new timestamp = \(timestamp)")
locationLogs["longitude"] = location.longitude
locationLogs["latitude"] = location.latitude
locationLogs["altitude"] = altitude
locationLogs["timestamp"] = timestamp
}
And here I query it
var result : AnyObject?
override func viewDidLoad() {
super.viewDidLoad()
let query = PFQuery(className:"LocationLogs")
query.fromLocalDatastore()
query.findObjectsInBackgroundWithBlock( { (NSArray results, NSError error) in
if error == nil && results != nil {
self.result = results
println("count = \(self.result!.count)")
self.loggedItemsTableView.reloadData()
}else{
println("ERRRROOOORRRR HORROOORRR= \(error)")
}
})
}
I have tried to use this command:
result?.saveAllInBackground()
But this only gave back an error.
Can someone please give me the correct code on how to do this or give me a link showing me how.

Answer 1

Here is a full code explanation on how I solved it:
//create an Array
var tableData: NSArray = []
func queryAll() {
let query = PFQuery(className:"LocationLogs")
query.fromLocalDatastore()
query.findObjectsInBackgroundWithBlock( { (NSArray results, NSError error) in
if error == nil && results != nil {
println("array = \(results)" )
self.tableData = results!
self.loggedItemsTableView.reloadData()
}else{
println("ERRRROOOORRRR HORROOORRR= \(error)")
}
})
}
//Call save on the class and not the object
PFObject.saveAllInBackground(self.tableData as [AnyObject], block: { (success: Bool, error: NSError?) -> Void in
if (success) {
//Remember to unpin the data if it will no longer be needed
PFObject.unpinAllInBackground(self.tableData as [AnyObject])
println("Pinned Data has successfully been saved")
}else{
println("error= \(error?.localizedDescription)")
}
})

Answer 2

Use this to safely cast/checked your object
if let results = self.result { // this will verify if your self.result is a non-nil array of object
// if it has a value then it will be passed to results
// you can now safely proceed on saving your objects
PFObject.saveAllInBackground(results, block: { (succeeded, error) -> Void in
// additional code
if succeeded {
// alert, remove hud ......
}else{
if let reqError = error {
println(reqError.localizedDescription)
}
}
})
}

struct log {
// this is dummy datastructure that imitate some part of your code ... you dont need it
var title = ""
var descriptionOf = ""
}
struct LocationInfo{
var title:String!
var description:String!
var location:PFGeoPoint!
var timestamp:NSDate!
var username:String
}
var locationManager = CLLocationManager()
var arrayOfLocations = [LocationInfo]()
func submitButton(sender: AnyObject) {
var logData = log()
var point = OneLocation(locationManager)
let username = PFUser.currentUser()?.username
var locationLogs = PFObject(className: "")
locationLogs["title"] = logData.title
locationLogs["description"] = logData.descriptionOf
locationLogs["Location"] = point
locationLogs["username"] = username
locationLogs["TimeStamp"] = locationManager.location.timestamp
locationLogs.saveInBackgroundWithBlock { (success:Bool, error:NSError?) -> Void in
if error == nil
{
println("data was save")
}
}
}
func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
CLGeocoder().reverseGeocodeLocation (manager.location, completionHandler: {(placemarks, error)->Void in
var UserCurrentLocation:CLLocationCoordinate2D = manager.location.coordinate
// println("User's parking Location : \(UserCurrentLocation.latitude) \(UserCurrentLocation.longitude)")
if (error != nil) {
println("Error")
return
}
locationManager.stopUpdatingLocation()
})
}
func OneLocation(Manager:CLLocationManager)->PFGeoPoint{
var latitude = Manager.location.coordinate.latitude
var longitude = Manager.location.coordinate.longitude
var point = PFGeoPoint(latitude: latitude, longitude: longitude)
return point
}
func QueryFromParse(){
var query = PFQuery(className: "")
query.findObjectsInBackgroundWithBlock { (objects:[AnyObject]?, error:NSError?) -> Void in
if error == nil
{
if let new_objects = objects as? [PFObject]
{
for SingleObject in new_objects
{
// with this single object you could get the description, title , username,etc
var location = SingleObject["Location"] as! PFGeoPoint
var username = SingleObject["username"] as! String
var title = SingleObject["title"] as! String
var time = SingleObject["TimeStamp"] as! NSDate
var description = SingleObject["description"] as! String
var singleLocationInfo = LocationInfo(title: title, description: description, location: location, timestamp: time, username: username)
arrayOfLocations.append(singleLocationInfo)
// reload data for the tableview
}
}
}
else
{
println("error")
}
}
}
Therefore you have an arrayoflocations that can be used to populate data in your tableView
Struct log is a dummy datastructure
And also I don't know if that was what you wanted ... but you should get the idea..
Hope that helps..
