UITableView Won't Display Data - ios

Question

I have a UITableView and it refuses to show any data, Xcode isn't showing any errors or warnings. Not sure why this is because the same code was working in a different app (obviously the names of array and tableview were different). I have the delegate and datasource both set as the view view-controller. If there is anything i missed please tell me!
Here is my code:
#import "ViewController.h"
#interface UIViewController ()
#end
#implementation ViewController
#synthesize CafeTableView;
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[self performSelector:#selector(RetriveData)];
[CafeTableView reloadData];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)RetriveData {
PFQuery *query = [PFQuery queryWithClassName:#"CafeList"];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error) {
NSLog(#"%#",objects);
NSLog(#"Successfully retrieved %d Cafes.", objects.count);
cafeListArry = [[NSArray alloc] initWithArray:objects];
}else{
UIAlertView *theAlert = [[UIAlertView alloc] initWithTitle:#"Error"
message:(#"There has been an error loading the Cafe List Please Try Again!")
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[theAlert show];
NSLog(#"%#",error);
}
}];
[CafeTableView reloadData];
}
//-------------------TABLE VIEW-----------------------
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return cafeListArry.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"CafeCell";
CafeListCell *cell = [CafeTableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
// Configure the cell...
PFObject *tempObject = [cafeListArry objectAtIndex:indexPath.row];
cell.title.text = [tempObject objectForKey:#"CafeName"];
cell.detail.text = [tempObject objectForKey:#"NumberOfStars"];
return cell;
}
#end

Answer 1

Move your call to reloadData inside the block as others have suggested and change the if condition as follows:
- (void)RetriveData {
PFQuery *query = [PFQuery queryWithClassName:#"CafeList"];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (objects) {
NSLog(#"%#",objects);
NSLog(#"Successfully retrieved %d Cafes.", objects.count);
cafeListArry = [[NSArray alloc] initWithArray:objects];
[CafeTableView reloadData]; // HERE
}else{
UIAlertView *theAlert = [[UIAlertView alloc] initWithTitle:#"Error"
message:(#"There has been an error loading the Cafe List Please Try Again!")
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[theAlert show];
NSLog(#"%#",error);
}
}];
}
Also, as suggested by Lyndsey in the comments, change the following line
cell.detail.text = [tempObject objectForKey:#"NumberOfStars"];
to
cell.detail.text = [[tempObject objectForKey:#"NumberOfStars"] stringValue];
because you said that it's a number, not a string.

Please check the delegates are connected in xib file or not if not then please connect properly and please call the [tableview reloadData]; method at the time when you want bind the data with table
