How can i upload a row in Parse.com?
This is my query code:
func queryFromParse(){
self.arrayOfDetails.removeAll()
let query = PFQuery(className: "currentUploads")
query.orderByDescending("createdAt")
query.findObjectsInBackgroundWithBlock { (objects:[AnyObject]?, error:NSError?) -> Void in
if error == nil
{
if let newObjects = objects as? [PFObject] {
for oneobject in newObjects {
let text = oneobject["imageText"] as! String
let username = oneobject["username"] as! String
let deviceID = oneobject["identifierForVendor"] as! String
let reportedCount = oneobject["reportedCount"] as! String
let time = oneobject.createdAt!
if let userImage = oneobject["imageFile"] as? PFFile {
let userImage = oneobject["imageFile"] as! PFFile
let imageURL = userImage.url // <- Bruker nå userImage.URL, henter ikke bildefilen med en gang
let OneBigObject = Details(username: username, text: text, CreatedAt: time, image: imageURL!, deviceID: deviceID, reportedCount: reportedCount)
//let OneBigObject = Details(username: username, text: text, CreatedAt: time, image: imageURL!)
self.arrayOfDetails.append(OneBigObject)
dispatch_async(dispatch_get_main_queue()) { self.collectionView.reloadData() }
}
}
}
}
}
}
I want to update the "reportedCount" when the image is reported. I have a code that i have been using, but that created new rows in another class for each report, and I want only to update the "reportedCount":
@IBAction func reportContentAction(sender: AnyObject) {
let buttonPosition = sender.convertPoint(CGPointZero, toView: self.collectionView)
let indexPath = self.collectionView.indexPathForItemAtPoint(buttonPosition)
////
println(indexPath?.item)
////
let post = self.arrayOfDetails[indexPath!.item]
var alertMessage = NSString(format:"*User: %@\r *Text: %@\r *Created at %@", post.username, post.text, post.CreatedAt)
var reportAlert = UIAlertController(title: "Report Content", message:alertMessage as String, preferredStyle: UIAlertControllerStyle.Alert)
reportAlert.addAction(UIAlertAction(title: "Yes", style: .Default, handler: { (action: UIAlertAction!) in
println("Handle Report Logic here")
var currentUploads = PFObject(className: "banned")
currentUploads["username"] = post.username
currentUploads["imageText"] = post.text
currentUploads["imageFile"] = post.image
currentUploads["identifierForVendor"] = post.deviceID
currentUploads["flaggedBy"] = PFUser.currentUser()?.username
currentUploads["flaggedByUUID"] = UIDevice.currentDevice().identifierForVendor.UUIDString
currentUploads.saveInBackgroundWithBlock({ (success: Bool, error: NSError?) -> Void in
if error == nil{
//**Success saving, now save image.**//
currentUploads.saveInBackgroundWithBlock({ (success: Bool, error: NSError?) -> Void in
if error == nil{
// Take user home
print("Data uploaded")
// Show UIAlertView
let alert = UIAlertView()
alert.title = "Message"
alert.message = "You report has been sent. Thank you for your support."
alert.addButtonWithTitle("Close")
alert.show()
}
else{
print(error)
}
})
}
else{
print(error)
}
})
}))
reportAlert.addAction(UIAlertAction(title: "Cancel", style: .Default, handler: { (action: UIAlertAction!) in
println("Handle Cancel Logic here")
}))
presentViewController(reportAlert, animated: true, completion: nil)
}
You should be keeping a reference to oneobject
, or more broadly, all of the objects
returned from the query. Now when something changes you can get the appropriate instance from the objects
array and then update and save it to modify the existing 'row'.
