Issue with running through NSArray - Obj C - ios

Question

I have an NSDictionary objectreturned from my server. I am using it to populate information on a UITableViewController. My issue is that when I am processing each object returned, it seems to duplicate, lets say I get 2 objects returned. It will make 2 table cells but with only the first object's data. So lets say the title section from both objects is "yes" and "no". It would populate the list with the first object title so it would show, yes and yes.
Here is what happens:
Controller is loaded:
- (void)viewDidLoad
{
[super viewDidLoad];
// MAKE REQuEST TO SERVER
[self makeRequests];
}
runs the request from server which stores information as follow:
NSDictionary* json = [NSJSONSerialization
JSONObjectWithData:returnData //1
options:kNilOptions
error:&error];
self.googlePlacesArrayFromAFNetworking = [json objectForKey:#"requested_data"];
[self.tableView reloadData];
than the cellForRowAtIndexPath runs:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"timelineCell";
FBGTimelineCell *cell = (FBGTimelineCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell)
{
cell = [[FBGTimelineCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
cell.usernameLabel.text = [_googlePlacesArrayFromAFNetworking[indexPath.row] objectForKey:#"name"]; <!-- here is where the title example I was talking about happens
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
[cell initTimelineCell];
}
UIImage *img = [UIImage imageNamed:[NSString stringWithFormat:#"%d.jpg", indexPath.row]];
cell.photoView.image = img;
return cell;
}
Here is my googlePlacesArr...
#property (strong, nonatomic) NSArray *googlePlacesArrayFromAFNetworking;
Here is my numberOfRowsInSection
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [self.googlePlacesArrayFromAFNetworking count];
}
Suggestions thoughts? Let me know if you need anything else.
UPDATE:
Also I think its important to note I am using this:

As a base for populating my returned data.

Answer 1

This usually happens when the cell gets recycled if your tableView:cellForRowAtIndexPath: method fails to set some of the members of recycled objects.
That is precisely what happens in your code: when the cell is recycled, you never set its usernameLabel.text, so the recycled value may be shown multiple times.
You should move the code that sets up cell's properties outside of the if statement to fix this problem:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"timelineCell";
FBGTimelineCell *cell = (FBGTimelineCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell)
{
cell = [[FBGTimelineCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
[cell initTimelineCell];
}
// This line is moved from the "if" statement
cell.usernameLabel.text = [_googlePlacesArrayFromAFNetworking[indexPath.row] objectForKey:#"name"];
UIImage *img = [UIImage imageNamed:[NSString stringWithFormat:#"%d.jpg", indexPath.row]];
cell.photoView.image = img;
return cell;
}

Answer 2

Try this:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
/* /////// Custom code ////// */
cell.usernameLabel.text = [_googlePlacesArrayFromAFNetworking[indexPath.row] objectForKey:#"your_key_name"];
}
