    <p>I'm doing this in kind of a roundabout way. I'm pulling users who are current users of my app as well as Facebook friends with the current user.</p> <p>When you print friendUsers [which is an array] you get this:</p> <pre><code>"&lt;PFUser:1234567:(null)&gt; {\n fbId = abcdefg;\n username = ausername;\n}" ) </code></pre> <p>I obviously swapped out some of the info for simplicity, but you get the idea.</p> <p>So if I have an array of a lot of users, I'll want to pull the fbId, and query facebook and get their profile pic to display in a table. Then you can just tap their profile pic. The idea is to change who the object is assigned to. </p> <p>I'm getting an incompatible pointer to integer conversion sending NSIndexPath strong to parameter of type NSUInteger in <code>didSelectRowAtIndexPath</code>. </p> <p>Not only that, but I realize here I'm just selecting the one user here:</p> <pre><code>PFUser *facebookID = [[PFUser alloc] init]; facebookID = [friendUsers objectAtIndex:0]; </code></pre> <p>That's because at the moment I only have one other user that has my app installed. I was just doing this to see if my app was working when querying Facebook. It is but, how would I grab all of the facebookIDs if there's lots of users?</p> <pre><code>#import "FacebookFriendViewController.h" #import "MainQueryViewController.h" #import &lt;Parse/Parse.h&gt; @interface FacebookFriendViewController () @end @implementation FacebookFriendViewController @synthesize friendUsers; @synthesize pic; @synthesize object; - (id)initWithStyle:(UITableViewStyle)style { self = [super initWithStyle:style]; if (self) { // Custom initialization } return self; } - (void)viewDidLoad { [super viewDidLoad]; NSLog(@"This is what was passed to the view controller."); NSLog(@"Printing friendUsers: %@", friendUsers); NSLog(@"%@", object); } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } #pragma mark - Table view data source - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { #warning Potentially incomplete method implementation. // Return the number of sections. return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { NSLog(@"The count is... count=%d",[friendUsers count]); // Return the number of rows in the section. return [friendUsers count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"friendCell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; PFUser *facebookID = [[PFUser alloc] init]; facebookID = [friendUsers objectAtIndex:0]; NSString *fbIdString = [[NSString alloc] init]; fbIdString = [facebookID objectForKey:@"fbId"]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } NSLog(@"This is a facebook ID:%@", fbIdString); NSURL *profilePictureURL = [NSURL URLWithString:[NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?type=large", fbIdString]]; NSData *picData = [NSData dataWithContentsOfURL:profilePictureURL]; UIImageView *fbPic = (UIImageView *)[self.view viewWithTag:1001]; [fbPic setImage:[UIImage imageWithData:picData]]; // Configure the cell... return cell; } #pragma mark - Table view delegate - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath]; [object setObject:[friendUsers objectAtIndex:indexPath] forKey:@"assignedTo"]; } @end </code></pre> <p>Thanks for your help</p> <p><strong>UPDATE</strong></p> <p>Per HRM's inquiry, here is what is sent to the friend picker view.</p> <pre><code> PF_FBRequest *request = [PF_FBRequest requestForMyFriends]; [request startWithCompletionHandler:^(PF_FBRequestConnection *connection, id result, NSError *error) { if (!error) { // result will contain an array with your user's friends in the "data" key NSArray *friendObjects = [result objectForKey:@"data"]; NSMutableArray *friendIds = [NSMutableArray arrayWithCapacity:friendObjects.count]; // Create a list of friends' Facebook IDs for (NSDictionary *friendObject in friendObjects) { [friendIds addObject:[friendObject objectForKey:@"id"]]; } // Construct a PFUser query that will find friends whose facebook ids // are contained in the current user's friend list.

    1. COHow u adding data to friendUsers array? Seems like the contents of array is NSDictionary. You need to take the content as NSDictionary and then parse accordingly.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
