PFQueryTableViewController does not show user cells

Question

I have a subclass of PFQueryTableViewController which I am trying to show as a container (as a subtitle). My problem is that I cannot get user cells to appear in a table. I checked the following with debugging:

• The table view is added to the parent view.
• Tableview is a PFQueryTableView controller, as it includes default updates
• PFQuery returns the correct number of objects
• The CellForRowAtIndexPath method is called and repeated through the correct number of times.
• The correct data from Parse is transferred to different labels in the cells
• These labels are connected via IBOulets in my subclass of UITableViewCell. When I try to access shortcuts, it works correctly when it accesses a subclass and label

I have everything that works here correctly, except that it is actually a box! What am I missing?

This is my cellForRowAtIndexPath code:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object{ static NSString *CellIdentifier = @"RoundCell"; RoundCell* cell = [tableView dequeueReusableCellWithIdentifier: CellIdentifier]; if (cell == nil) { cell = [[RoundCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } // get string values from Parse NSString * teeString =[object objectForKey:@"roundTee"]; NSString* courseString = [object objectForKey:@"roundCourse"]; NSString * courseString2 = [[courseString stringByAppendingString:@" - "]stringByAppendingString:teeString]; NSString * dateString = [object objectForKey:@"roundDate"]; NSString * scoreString = [object objectForKey:@"roundScore"]; NSString * differentialString = [object objectForKey:@"roundDifferential"]; cell.courseNameCell.text = courseString2; cell.dateCell.text = dateString; cell.scoreCell.text= scoreString; cell.differentialCell.text=differentialString; return cell; }

The correct method is to call the custom cell in cellForRowAtIndexPath.

Check out two main things:

1. on the storyboard and click on a cell in the attribute inspector, check that the cell has the correct identifier

2. set cellForRowAtIndexPath like this:

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object{ CustomCell *cell = (CustomCell * )[self.tableView dequeueReusableCellWithIdentifier:@"YOUR CELL NAME" forIndexPath:indexPath]; 

So in your case try:

  - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object{ CustomCell *cell = (CustomCell * )[self.tableView dequeueReusableCellWithIdentifier:@"YOUR CELL NAME" forIndexPath:indexPath]; NSString * teeString =[object objectForKey:@"roundTee"]; NSString* courseString = [object objectForKey:@"roundCourse"]; NSString * courseString2 = [[courseString stringByAppendingString:@" - "]stringByAppendingString:teeString]; NSString * dateString = [object objectForKey:@"roundDate"]; NSString * scoreString = [object objectForKey:@"roundScore"]; NSString * differentialString = [object objectForKey:@"roundDifferential"]; cell.courseNameCell.text = courseString2; cell.dateCell.text = dateString; cell.scoreCell.text= scoreString; cell.differentialCell.text=differentialString; return cell; } 

Remember to import the custom cell subclass into File.m

 #import "YourCustomCell.h" 

and set the cell in the identity inspector

If you created your UITableView cell in XIB (which sounds like you), you cannot use the alloc init paradigm to initialize your object. You should use:

 cell = [[[NSBundle mainBundle] loadNibNamed:@"MyCellXibFile" owner:nil options:nil] objectAtIndex:0]

Swift Version (up to 1.2):

 import UIKit class JPUsersTableViewController: PFQueryTableViewController { override init!(style: UITableViewStyle, className: String!) { super.init(style: style, className: className) textKey = "username" pullToRefreshEnabled = true paginationEnabled = true objectsPerPage = 25 } required init(coder aDecoder: NSCoder) { super.init(coder: aDecoder) } override func viewDidLoad() { super.viewDidLoad() title = "Users" tableView.registerClass(PFTableViewCell.self, forCellReuseIdentifier: kTableViewCellIdentifier) tableView.separatorInset.right = tableView.separatorInset.left tableView.tableFooterView = UIView(frame: CGRectZero) view.backgroundColor = kbackgroundColor let returnIcon = UIBarButtonItem(image: kNavBarReturnIcon, style: .Plain, target: navigationController, action: "popViewControllerAnimated:") returnIcon.tintColor = kToolbarIconColor navigationItem.leftBarButtonItem = returnIcon tableView.reloadData() addPullToRefresh() } override func queryForTable() -> PFQuery! { let query = PFUser.query() query.whereKey("username", notEqualTo: PFUser.currentUser().username) query.orderByAscending("username") //if network cannot find any data, go to cached (local disk data) if (self.objects.count == 0){ query.cachePolicy = kPFCachePolicyCacheThenNetwork } return query } // MARK: - Navigation override func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!, object: PFObject!) -> PFTableViewCell! { let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as PFTableViewCell cell.textLabel?.text = object["username"] as? String if let profileImage = object["profileImage"] as? PFFile { cell.imageView.file = profileImage } else { cell.imageView.image = kProfileDefaultProfileImage } cell.textLabel?.font = UIFont(name: kStandardFontName, size: kStandardFontSize) cell.textLabel?.textColor = UIColor.whiteColor() cell.backgroundColor = kbackgroundColor return cell } override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat { return 50 } }
