I am building a Vote/Instagram-type app, where a user selects a non-user-made photo which is pushed into a Timeline.
I have built out the selection screen and button, and the Timeline. For some reason, I can only guess that it has something to do with the chronology of saving the PFObject (the chose photo), the Timeline is displaying the photo chosen BEFORE the currently chosen photo.
The following block is the 'Select' button on the 'SelectScreenVC':
#IBAction func selectNext(sender: UIButton) {
let imageData = UIImagePNGRepresentation(lgImgURL.image)
let imageFile = PFFile(name: "\(cName.text!)", data: imageData)
var user = PFUser.currentUser()
user["nextChosen"] = "\(cName.text!)"
user["imageFile"] = imageFile
var userNextPhoto = PFObject(className: "UserNextPhoto")
userNextPhoto["username"] = PFUser.currentUser().username
userNextPhoto["cName"] = "\(cName.text!)" as String
userNextPhoto["imageFile"] = imageFile
userNextPhoto.saveInBackgroundWithBlock { (success: Bool!, error: NSError!) -> Void in
if error == nil {
println("User \(PFUser.currentUser().username) chose: \(self.cName.text!)")
} else {
println(error)
}
}
self.navigationController?.popToViewController(timeLineVC, animated: true)
}
This the TimeLineVC. I have the function which creates the timeline array and I skipped some of the TableView methods, except for the cellForRowAtIndexPath.
class TimeLineViewController: UITableViewController {
var timelineData:NSMutableArray = NSMutableArray()
override func viewDidLoad() {
super.viewDidLoad()
loadData()
}
func loadData() {
timelineData.removeAllObjects()
var findTimelineData:PFQuery = PFQuery(className: "UserNextPhoto")
findTimelineData.findObjectsInBackgroundWithBlock { (objects: [AnyObject]!, error: NSError!) -> Void in
if error == nil {
for object in objects {
self.timelineData.addObject(object)
}
} else {
NSLog("Error: %# %#", error, error.userInfo!)
}
let array: NSArray = self.timelineData.reverseObjectEnumerator().allObjects
self.timelineData = NSMutableArray(array: array)
self.tableView.reloadData()
}
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("timelineCell", forIndexPath: indexPath) as TimelineTableViewCell
let userNextPhoto:PFObject = self.timelineData.objectAtIndex(indexPath.row) as PFObject
let nextPhoto:PFObject = self.timelineData.objectAtIndex(indexPath.row) as PFObject
cell.usernameLabel.text = PFUser.currentUser().username
cell.cName.text = (userNextPhoto["cName"] as String)
return cell
}
I appreciate any help or insight!
That is what is going on: the new photo has not finished uploading when you pop the view controller. You can either wait for the photo to finish uploading (which is not a great UX), or you can pass back a reference to the newly-saved object back up to the popped view controller which can then display the new photo right away without waiting for the upload to finish.

I am trying to create a tableView of users from my Parse database that are in the same class (at school). All users have to have a username, but not all will have given the app their full name or set a profile picture. I use this code:
let studentsQuery = PFQuery(className:"_User")
studentsQuery.whereKey("objectId", containedIn: studentsArray! as! [AnyObject])
let query2 = PFQuery.orQueryWithSubqueries([studentsQuery])
query2.findObjectsInBackgroundWithBlock {
(results: [PFObject]?, error: NSError?) -> Void in
if error != nil {
// Display error in tableview
} else if results! == [] {
spinningActivity.hideAnimated(true)
print("error")
} else if results! != [] {
if let objects = results {
for object in objects {
if object.objectForKey("full_name") != nil {
let studentName = object.objectForKey("full_name")! as! String
self.studentNameResults.append(studentName)
}
if object.objectForKey("username") != nil {
let studentUsername = object.objectForKey("username")! as! String
self.studentUsernameResults.append(studentUsername)
}
if object.objectForKey("profile_picture") != nil {
let studentProfilePictureFile = object.objectForKey("profile_picture") as! PFFile
studentProfilePictureFile.getDataInBackgroundWithBlock({ (image: NSData?, error: NSError?) in
if error == nil {
let studentProfilePicture : UIImage = UIImage(data: image!)!
self.studentProfilePictureResults.append(studentProfilePicture)
} else {
print("Can't get profile picture")
// Can't get profile picture
}
self.studentsTableView.reloadData()
})
spinningActivity.hideAnimated(true)
} else {
// no image
}
}
}
} else {
spinningActivity.hideAnimated(true)
print("error")
}
}
This code works fine if all of the users have a username, full_name, and a profile_picture. I can't figure out, however, how to get a tableView of the usernames of a user and add a user's name or picture to the user's corresponding tableViewCell only if the user has a picture. Here is how my tableView is configured:
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return studentUsernameResults.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("studentsCell", forIndexPath: indexPath) as! StudentsInClassInformationTableViewCell
cell.studentProfilePictureImageView.layer.cornerRadius = cell.studentProfilePictureImageView.frame.size.width / 2
cell.studentProfilePictureImageView.clipsToBounds = true
cell.studentProfilePictureImageView.image = studentProfilePictureResults[indexPath.row]
cell.studentUsernameLabel.text = studentUsernameResults[indexPath.row]
cell.studentNameLabel.text = studentNameResults[indexPath.row]
return cell
}
The studentProfilePictureResults, studentUsernameResults, and studentNameResults come from arrays of the user's picture, username, and name results pulled from Parse. If a user does not have a profile picture, I get the error, Index is out of range. Obviously, this means that there are, say, three names, three usernames, and only two pictures and Xcode doesn't know how to configure the cell. My question: How can I set a tableView up of a user's username and place their name and profile picture in the same cell, only if they have one?
Trying to store the different attributes in different arrays will be a problem, since as you have found, you end up with problems where a particular user doesn't have an attribute. You could use an array of optionals, so that you could store nil for an absent attribute, but it is much simpler to store the PFObject itself in a single array and accessing the attributes in cellForRowAtIndexPath rather than splitting out the attributes.
Since fetching the photo requires a separate, asynchronous, operation, you can store it separately. Rather than using an array to store the retrieved photos, which would have the same problem of ordering, you can use a dictionary, indexed by the user id; although for a large number of students it would probably be more efficient to use something like SDWebImage to download the photos as required in cellForRowAtIndexPath.
// these are instance properties defined at the top of your class
var students: [PFObject]?
var studentPhotos=[String:UIImage]()
// This is in your fetch function
let studentsQuery = PFUser.Query()
studentsQuery.whereKey("objectId", containedIn: studentsArray! as! [AnyObject])
let query2 = PFQuery.orQueryWithSubqueries([studentsQuery])
query2.findObjectsInBackgroundWithBlock {
(results: [PFObject]?, error: NSError?) -> Void in
guard (error == nil) else {
print(error)
spinningActivity.hideAnimated(true)
return
}
if let results = results {
self.students = results
for object in results {
if let studentProfilePictureFile = object.objectForKey("profile_picture") as? PFFile {
studentProfilePictureFile.getDataInBackgroundWithBlock({ (image: NSData?, error: NSError?) in
guard (error != nil) else {
print("Can't get profile picture: \(error)")
return
}
if let studentProfilePicture = UIImage(data: image!) {
self.studentPhotos[object["username"]!]=studentProfilePicture
}
}
}
spinningActivity.hideAnimated(true)
self.tableview.reloadData()
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if self.students != nil {
return self.students!.count
}
return 0
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("studentsCell", forIndexPath: indexPath) as! StudentsInClassInformationTableViewCell
cell.studentProfilePictureImageView.layer.cornerRadius = cell.studentProfilePictureImageView.frame.size.width / 2
cell.studentProfilePictureImageView.clipsToBounds = true
let student = self.students[indexPath.row]
if let studentPhoto = self.studentPhotos[student["username"]!] {
cell.studentProfilePictureImageView.image = studentProfilePictureResults[indexPath.row]
} else {
cell.studentProfilePictureImageView.image = nil
}
cell.studentUsernameLabel.text = student["username"]!
if let fullName = student["full_name"] {
cell.studentNameLabel.text = fullName
} else {
cell.studentNameLabel.text = ""
return cell
}
A few other pointers;
The use of _ to separate words in field names isn't really used in the iOS world; camelCase is preferred, so fullName rather than full_name
It looks like your Parse query could be more efficient if you had a class field or reference object so that you didn't need to supply an array of other class members.
I am trying to reload my table view using
self.tableView.reloadData()
It works properly if I'm loading static datasource using array. Everything work properly.
But when I try to use my query function with parse, it loads a new cell but the contents of the tableview cell doesn't change. If I re-open the app, the cells will update properly.
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cellIdentifier = "EmpPostTVCellIdentifier"
let cell: EmpPostTVCell? = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as? EmpPostTVCell
//If datasource
if dataSource.isEmpty{
fetchDataFromParse()
print("no posts")
}
let itemArr:PFObject = self.dataSource[indexPath.row]
cell?.companyPostLabel.text = (PFUser.currentUser()?.objectForKey("companyName")!.capitalizedString)! as String
cell?.occupationPostLabel.text = itemArr["occupation"]!.capitalizedString as String
cell?.countryPostLabel.text = itemArr["country"]!.capitalizedString as String
let companyImage: PFFile?
companyImage = PFUser.currentUser()?.objectForKey("profileImageEmployer") as? PFFile
companyImage?.getDataInBackgroundWithBlock({ (data, error) -> Void in
if error == nil{
cell?.companyLogoImage.image = UIImage(data: data!)
}
})
let dateArr = createdByDate[indexPath.row]
let strDate = Settings.dateFormatter(dateArr)
cell?.closingDateLabel .text = strDate
return cell!
}
I am using pull to refresh my tableviews contents using this code
func refresh(sender:AnyObject)
{
dispatch_async(dispatch_get_main_queue(), { () -> Void in
self.fetchDataFromParse()
self.tableView.reloadData()
self.refreshControl?.endRefreshing()
})
}
with or without the dispatch_asynch function the results remains the same. It just add new tableviewcell but the contents in it does not change. Any ideas guys?
edit 1 :
func fetchDataFromParse() {
// MARK: - JOB POST QUERY
if PFUser.currentUser()?.objectId == nil{
PFUser.currentUser()?.saveInBackgroundWithBlock({ (success, error) -> Void in
let query = PFQuery(className: "JobPost")
//creating a pointer
let userPointer = PFUser.objectWithoutDataWithObjectId(PFUser.currentUser()?.objectId)
query.whereKey("postedBy", equalTo: userPointer)
query.orderByDescending("createdAt")
let objects = query.findObjects()
for object in (objects as? [PFObject])!{
//print(object.objectId)
self.dataSource.append(object)
self.createdByDate.append((object.objectForKey("closingDate") as? NSDate)!)
print(self.dataSource)
print(self.createdByDate)
}
})
} else {
let query = PFQuery(className: "JobPost")
//creating a pointer
let userPointer = PFUser.objectWithoutDataWithObjectId(PFUser.currentUser()?.objectId)
query.whereKey("postedBy", equalTo: userPointer)
query.orderByDescending("createdAt")
let objects = query.findObjects()
for object in (objects as? [PFObject])!{
//print(object.objectId)
self.dataSource.append(object)
self.createdByDate.append((object.objectForKey("closingDate") as? NSDate)!)
print(self.dataSource)
print(self.createdByDate)
}
}//end of PFUser objectID == nil else clause
}
Let's see the content of the fetchDataFromParse() function where I presume you're filling the self.dataSource array
Try to call self.tableview.reloadData() when fetchDataFromParse() is finished.
Check whether your dataSource array is empty at the end of your fetchDataFromParse method
PFUser.currentUser()?.saveInBackgroundWithBlock is an asynchronus method. So your tableView cell is having no data.
I have a pointer in my parse. The pointer tells me who uploaded the images. I am trying to retrieve the username and the profile picture of the uploader. To do that I have put query.includeKey("uploader") . Users are managed through the user class. and posts are managed in the posts class. To retrieve the images and names I have the below code.
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCellWithReuseIdentifier("newview", forIndexPath: indexPath) as! NewCollectionViewCell
let item = self.votes[indexPath.row]
// Display "initial" flag image
var initialThumbnail = UIImage(named: "question")
cell.postsImageView.image = initialThumbnail
if let pointer = item["uploader"] as? PFObject {
cell.userName!.text = item["username"] as? String
}
if let profile = item["uploader"] as? PFObject {
cell.profileImageView.loadInBackground({ (image:UIImage, error:NSError) -> Void in
if error != nil{
cell.profileImageView.image = image
}
})}
if let votesValue = item["votes"] as? Int
{
cell.votesLabel?.text = "\(votesValue)"
}
// Fetch final flag image - if it exists
if let value = item["imageFile"] as? PFFile {
cell.postsImageView.file = value
cell.postsImageView.loadInBackground({ (image: UIImage?, error: NSError?) -> Void in
if error != nil {
cell.postsImageView.image = image
}
})
}
return cell
}
However errors are happening saying that loadinbackround can't be invoked with an argument list of type (UIImage, NSError)->void. The strange part is that the error is only for the first part where I try to retrieve the images for the user. I am really stuck in this and want help. Is my pointer retrieving wrong? Thank you.

if image != nil {
dispatch_async(dispatch_get_main_queue(),{
cell.postsImageView.image = image
})
}else{
println("Image not available")
}
}else{
println(Image Downloading error: \(error))
}
})
Try this , i think this will help you :)
Try to replace your loadInBackground method with the below:
cell.postsImageView.loadInBackground({ (image: UIImage!, error: NSError!) -> Void in
if error == nil {
cell.postsImageView.file = value
cell.postsImageView.image = image
}
})
}
You have two issues here, the first being the way you pass the closure to the loadInBackground method
The compiler error is because you're trying to call the method with non-optional closure parameters.
In the cell.postsImageView.loadInBackground call you use optionals, while in the cell.profileImageView.loadInBackground you don't.
Closure parameter types are important, that's why the compiler is complaining.
I'd suggest skipping the types and defining the closure like this:
cell.profileImageView.loadInBackground { image, error in
if error != nil{
cell.profileImageView.image = image
}
})}
The other and probably your main issue is that you don't set a file for the profile. So, if we say that the profile image is stored under imageFile in the uploader object, you would use:
if let profile = item["uploader"] as? PFObject,
profileImageFile = profile["imageFile"] as? PFFile {
cell.profileImageView.file = profileImageFile
cell.profileImageView.loadInBackground { image, error in
if error == nil {
cell.profileImageView.image = image
}
}
}
Though, as the Parse documentation says, the method downloads and displays the image:
Once the download completes, the remote image will be displayed.
https://parse.com/docs/ios/api/Classes/PFImageView.html#//api/name/loadInBackground:
If you don't need any special error handling and since you already have a placeholder image, try loading the image like this:
if let profile = item["uploader"] as? PFObject,
profileImageFile = profile["imageFile"] as? PFFile {
cell.profileImageView.file = profileImageFile
cell.profileImageView.loadInBackground()
}
I am trying to retrieve user profile image from parse. I have a collection view and I am retrieving all images people posted. I want to show each users profile image in the cell as well. I was using the below code
override func viewDidLoad() {
super.viewDidLoad()
let query = PFQuery(className: "Posts")
query.includeKey("pointName")
query.findObjectsInBackgroundWithBlock{(question:[AnyObject]?,error:NSError?) -> Void in
if error == nil

if let allQuestion = question as? [PFObject]
{
self.votes = allQuestion

However I found out that it sets profile image to the current user and not the user who posted the image. How can I do this? Thank you
UPDATE
so In parse my post class is
so I know who uploaded it but I don't know how to retrieve the profile image for this specific user.
You need to use a pointer that will point to the user who created the object. The profile photo should be in the user class. You then include the pointer in your query and that will return the user data.
okay, this might help you in objective-C
PFUser *user = PFUser *user = [PFUser currentUser];
[user fetchIfNeededInBackgroundWithBlock:^(PFObject *object, NSError *error) {
_profileImage.file = [object objectForKey:#"profilePicture"];
}];
I am having issues setting with Parse data and a UITableView. Everytime I run the application, whether on the simulator or my phone, the app stops working and the only thing the console shows is (lldb). When checking the debugger, only following two lines of code are highlighted.
findTimelineData.findObjectsInBackgroundWithBlock{
and
self.timelineData = array as NSMutableArray
Both have the error: Thread 1: EXC_BREAKPOINT (code=EXC_I386_BPT,subcode=0x0) and im not quite sure what that means...
Here are snippets of my code:
override func viewDidAppear(animated: Bool)
{
self.loadData()
}
func loadData()
{
timelineData.removeAllObjects()
var findTimelineData : PFQuery = PFUser.query()
findTimelineData.findObjectsInBackgroundWithBlock{
(objects: [AnyObject]!, error: NSError!)-> Void in
if error == nil
{
println("No error")
if let object = objects as? [PFObject!]
{
for object in objects
{
self.timelineData.addObject(object)
}
}
let array : NSArray = self.timelineData.reverseObjectEnumerator().allObjects
self.timelineData = array as NSMutableArray
self.tableView.reloadData()
}
}
}
and these would be the cells that i'm trying to load, but the code never gets this far...
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
println("loading cell")
let postCell : LocationTableViewCell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as LocationTableViewCell
let post : PFObject = self.timelineData.objectAtIndex(indexPath.row) as PFObject
postCell.imageView.image = post.objectForKey("currentLocation") as? UIImage
postCell.userInfo.text = post.objectForKey("FirstLastName") as? String
// Configure the cell...
return postCell
}
for the full code: http://pastebin.com/MN7qcFhq
this worked for me:
in your code just only replace
self.timelineData = array as NSMutableArray
to
self.timelineData = NSMutableArray(array: array)
Aren't you missing an s in:
if let object = objects as? [PFObject!]
{
for object in objects
{
self.timelineData.addObject(object)
}
}
Should be:
if let objects = objects as? [PFObject!]
{
for object in objects
{
self.timelineData.addObject(object)
}
}
Hey Buddy I got you on this one. I had the same issues but I got help and got it figured out.
This is your Load Function
Try this
func loadData(){
timelineData.removeAll(keepCapacity: false)
var findTimelineData:PFQuery = PFQuery(className:"Sweets")
findTimelineData.findObjectsInBackgroundWithBlock
{
(objects:[AnyObject]! , error:NSError!) -> Void in
if error == nil
{
self.timelineData = objects.reverse() as [PFObject]
//let array:NSArray = self.timelineData.reverseObjectEnumerator().allObjects
println(objects)
// self.timelineData = array as NSMutableArray
self.tableView.reloadData()
}
}
}
Then go to your
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
And change
let sweet:PFObject = self.timelineData.objectAtIndex(indexPath.row) as PFObject
To This
let sweet: PFObject = self.timelineData[indexPath.row] as PFObject
Whats going on is you are mixing some Obj C with Swift , the code you are following was probably written in Beta so make sure you go back and learn the differences. If you are still having problems check all your conditions if(error != nil) should not be in your code.
