UITableViewCell staying empty - ios

Question

I am trying to fill a UITableView with the objects of an NSMutableArray which is filled from a table in Parse. The array is definitely being filled (I checked its contents with an NSLog), but the table is staying empty. I have tried A LOT of different ways including the following:
- (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
TableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Cell"];
PFObject *postsObject = [postsArray objectAtIndex:indexPath.row];
cell.textLabel.text = [postsObject objectForKey:#"message"];
cell.textLabel.textAlignment = NSTextAlignmentCenter;
if (!cell) {
cell = [[TableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"Cell"];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
if (tableView == table) {
cell.textLabel.text = [postsArray objectAtIndex:indexPath.row];
}
return cell;
}
and the much simpler
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
TableViewCell *cell = [table dequeueReusableCellWithIdentifier:#"Cell"];
cell.messageLabel.text = [NSString stringWithFormat:[postsArray objectAtIndex:[indexPath row]]];
return cell;
}
Does anyone have any ideas?
Thanks in advance :)
EDIT:
My dataSource methods are:
- (NSInteger) numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return postsArray.count;
}
EDIT #2:
My code I'm using to fill my array and reload my tableView
PFQuery *findData = [PFQuery queryWithClassName:#"AllPosts"];
[findData setLimit:1000];
[findData findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (error == nil) {
for (PFObject *object in objects) {
PFObject *post = object[#"content"];
NSMutableArray *array = [[NSMutableArray alloc] initWithObjects:post, nil];
postsArray = array;
[table reloadData];
}
} else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Error" message:#"Unable To Load" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert show];
}
}];

Answer 1

You are doing it wrong , you are replacing the array with new data whenever you are finding a PFObject in objects, your code should be like this:-
//first alloc your array
postsArray=[[NSMutableArray alloc] init];
//Logic goes here
PFQuery *findData = [PFQuery queryWithClassName:#"AllPosts"];
[findData setLimit:1000];
[findData findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (error == nil) {
for (PFObject *object in objects) {
PFObject *post = object[#"content"];
NSMutableArray *array = [[NSMutableArray alloc] initWithObjects:post, nil];
[postsArray addObject:array];
[table reloadData];
}
} else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Error" message:#"Unable To Load" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert show];
}
}];

You also need to check if the cell object is actually returned. Also put in the following code after the call to dequeueReusableCellWithIdentifier:
if(!cell)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"Cell"];
}
This would solve your problem
