Table view populated from NSMutableArray not showing anything - ios

Question

I am trying to populate a tableView with objects received from a JSON request.
This is my viewDidLoad method:
- (void)viewDidLoad
{
[super viewDidLoad];
NSLog (#"HE ENTRADO EN HISTORIAL VC");
myObject = [[NSMutableArray alloc] init];
NSURL *apiURL = [NSURL URLWithString:
[NSString stringWithFormat:#"http://.. HIDDEN HERE.. /?client=%#&date=%#", #"1",#"2015-3-16"]];
NSURLRequest *request = [NSURLRequest requestWithURL:apiURL];
NSLog (#"HE MANDADO LA REQUEST DEL HISTORIAL");
[NSURLConnection sendAsynchronousRequest:request
queue:[NSOperationQueue mainQueue]
completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
if(data.length) {
NSString *responseString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
if(responseString && responseString.length) {
NSLog(#"dATOS RECIBIDOS EN HISTORIAL=%#", responseString);
NSLog (#"HE RECIBIDO LA REQUEST DEL HISTORIAL");
NSError *jsonError;
NSData *objectData = [responseString dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objectData
options:NSJSONReadingMutableContainers
error:&jsonError];
NSArray *messageArray = [json objectForKey:#"objects"];
historialServicios = [[NSMutableArray alloc]init];
// Parse and loop through the JSON
for (dictionary in messageArray) {
//datos de nivel objects
NSString * code = [dictionary objectForKey:#"code"];
NSString * date = [dictionary objectForKey:#"date"];
//datos de nivel client
NSDictionary *level2Dict = [dictionary objectForKey:#"client"];
id someObject = [level2Dict objectForKey:#"email"];
NSLog(#"ANTES DE ANADIR OBJETOS");
[historialServicios addObject:#{#"code": code, #"date": date, #"email":someObject}];
NSLog(#"DESPUES DE ANADIR OBJETOS");
NSLog(#"NOMBRE===%#",someObject);
NSString * email = someObject;
NSLog(#"EMAIL=%#",email);
NSLog(#"CODE=%#",code);
NSLog(#"DATE=%#",date);
//insertamos objetos en diccionario historialServicios
}
NSLog(#"++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++SERVICIOS RECIBIDOS=%#", historialServicios);
}
}
}];
NSLog(#"NUMERO DE ITEMS=%lu", (unsigned long)[historialServicios count]);
[self.tableView reloadData];
}
The last NSLog doesn't appear in the log console. The content of the NSMutableArray are shown in the console:
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++SERVICIOS RECIBIDOS=(
{
code = SV1000000103;
date = "2015-03-18";
email = "jose#gmail.com";
},
{
code = SV1000000113;
date = "2015-03-18";
email = "jose#gmail.com";
},
{
code = SV1000000104;
date = "2015-03-16";
email = "jose#gmail.com";
},
...
But nothing is shown on the table.
Here the tableView methods:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return historialServicios.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Cell" forIndexPath:indexPath];
NSString *email = [[historialServicios objectAtIndex:indexPath.row] valueForKey:#"email"];
NSLog(#"VALOR DEL EMAIL=%#", email);
cell.detailTextLabel.text = email;
return cell;
}
What am I doing wrong?

Answer 1

You should call [self.tableView reloadData] from inside the completion block just after "SERVICIOS RECIBIDOS=%#" line.
Calling it outside the block as you did, will make the table reloads it contents before you receive it from the server.
Hope it helps you, amigo.
