Swift Cells Not Displaying - ios

Question

I have a profile page that is made up of two custom tableview cells. The first custom cell is the user's info. The second custom cell is the user's friend. The first row is the user's info, and all of the cells after that are the user's friends. My code worked in Xcode 6, but stopped working after the update.
Problem: A user with 2 friends, their profile page should have a table with three cells: 1 user info cell, 2 friend cells. However, the first and second cell aren't showing. Only the third cell is showing.
Clarification: There should be three cells. Cell 1 is not showing. Cell 2 is not showing. But Cell 3 is showing. Cell 1 is the user's info. Cell 2 is one friend. Cell 3 is another friend.
Here's my code:
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return friendList.count + 1
}
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
if indexPath.row == 0{
return 182.0
}else{
return 95.0
}
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
if indexPath.row != 0{
let cell = tableView.dequeueReusableCellWithIdentifier("friendCell", forIndexPath: indexPath) as! ProfileFriendTableViewCell
let friend = friendList[indexPath.row - 1]
cell.nameLabel.text = friend[1]
cell.usernameLabel.text = friend[2]
cell.schoolLabel.text = friend[3]
cell.sendRequestButton.tag = indexPath.row
var profileImageExists = false
if profileImages != nil{
for profileImage in profileImages{
if profileImage.forUser == friend[2]{
profileImageExists = true
cell.friendImageProgress.hidden = true
cell.profilePic.image = UIImage(data: profileImage.image)
UIView.animateWithDuration(0.2, animations: {
cell.profilePic.alpha = 1
})
}
}
}else if loadingImages == true{
profileImageExists = true
cell.friendImageProgress.hidden = true
cell.profilePic.image = UIImage(named: "profileImagePlaceholder")
UIView.animateWithDuration(0.2, animations: {
cell.profilePic.alpha = 1
})
}
if profileImageExists == false{
if Reachability.isConnectedToNetwork() == true{
let query = PFUser.query()
query?.getObjectInBackgroundWithId(friend[0], block: { (object, error) -> Void in
if error == nil{
if let object = object as? PFUser{
let friendProfilePicture = object.objectForKey("profileImage") as? PFFile
friendProfilePicture?.getDataInBackgroundWithBlock({ (data, error) -> Void in
if data != nil{
let image = UIImage(data: data!)
cell.profilePic.image = image
if let managedObjectContext = (UIApplication.sharedApplication().delegate as! AppDelegate).managedObjectContext {
let newProfileImage = NSEntityDescription.insertNewObjectForEntityForName("ProfileImageEntity", inManagedObjectContext: managedObjectContext) as! ProfileImage
newProfileImage.forUser = friend[2]
newProfileImage.image = UIImagePNGRepresentation(image!)
do{
try managedObjectContext.save()
}catch _{
print("insert error")
}
}
}else{
cell.friendImageProgress.hidden = true
cell.profilePic.image = UIImage(named: "profileImagePlaceholder")
}
}, progressBlock: { (progress: Int32) -> Void in
let percent = progress
let progressPercent = Float(percent) / 100
cell.friendImageProgress.progress = progressPercent
cell.friendImageProgress.hidden = true
})
}
}
})
}
else{
cell.friendImageProgress.hidden = true
cell.profilePic.image = UIImage(named: "profileImagePlaceholder")
}
}
return cell
}else{
let cell = tableView.dequeueReusableCellWithIdentifier("profileTopCell", forIndexPath: indexPath) as! ProfileTableViewCell
var profileImageExists = false
if profileImages != nil{
for profileImage in profileImages{
if profileImage.forUser == PFUser.currentUser()!.username!{
profileImageExists = true
cell.profilePic.image = UIImage(data: profileImage.image)
}
}
}else if loadingImages == true{
profileImageExists = true
cell.profilePic.image = UIImage(named: "profileImagePlaceholder")
}
if profileImageExists == false{
if Reachability.isConnectedToNetwork() == true{
let profilePicture = PFUser.currentUser()!.objectForKey("profileImage") as? PFFile
profilePicture?.getDataInBackgroundWithBlock({ (data, error) -> Void in

}else{

}else{
cell.profilePic.image = UIImage(named: "profileImagePlaceholder")
}
}
cell.nameLabel.text = PFUser.currentUser()!.objectForKey("Name") as? String
cell.usernameLabel.text = PFUser.currentUser()!.objectForKey("username") as? String
let friendNumber = PFUser.currentUser()!.objectForKey("numberOfFriends") as? Int
if friendNumber != 1{
cell.numberOfFriendsLabel.text = "\(friendNumber!) Friends"
}else{
cell.numberOfFriendsLabel.text = "1 Friend"
}
return cell
}

Answer 1

Try to use estimatedRowHeightand rowHeight = UITableViewAutomaticDimension on your viewDidLoad or viewWillAppear and on heightForRowAtIndexPath return UITableViewAutomaticDimension, remember to put constraints on your custom cell, so these can work properly.

Answer 2

Thanks to Jeremy Andrews (https://stackoverflow.com/a/31908684/3783946), I found the solution:
"All you have to do is go to file inspector - uncheck size classes - there will be warnings etc.run and there is the data - strangely - go back to file inspector and check "use size classes" again, run and all data correctly reflected. Seems like in some cases the margin is set to negative."
It was just a bug.
