Tableview doesn't fire cellForRowtIndexPath method - iphone

Question

My situation:
I've got datasource and delegate connect in the storyboard
I've got for my UITableViewCell and identifier and also in code defined, etc.
I've got the array with data for my UITableView, in debug my data array is filled in viewDidload method
So everything seems right till I arrive to cellForRowIndexPath and numberOfRowsInSection. It doesn't go into the methods. When I
run further, debug is complete, don't get any faults, only a black
UITableView i get with nothing in. Really strange cus my array is
filled with data and everything is connected as it should be.
Some help is needed, i'm searching for days now!
If code is needed to help, ask me.
My code:
m.file:
#import "DagprogrammaDetailViewController.h"
#interface DagprogrammaDetailViewController ()
#end
#implementation DagprogrammaDetailViewController
{
NSMutableArray *DagprogrammaDetail;
}
#synthesize menuNaam;
#synthesize tableDagprogrammaDetail;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
self.navigationItem.title = menuNaam;
NSArray *dagarray = [menuNaam componentsSeparatedByString:#" "];
NSString *plaatsString = [dagarray objectAtIndex:1];
plaatsString = [plaatsString stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
//object ophalen
NSMutableString *urlString = [NSMutableString stringWithFormat:#"http://zesdaagse.mobi-app.be/WCFUrl/MobileService.svc/GetDagprogramma"];
NSURL *url = [NSURL URLWithString:urlString];
NSData *data = [NSData dataWithContentsOfURL:url];
NSError *error;
NSMutableDictionary *json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSMutableArray *id = [NSMutableArray array];
for(NSDictionary *item in json)
{
[id addObject:[item objectForKey:#"id"]];
}
int plaats = [plaatsString intValue];
plaats -= 1;
//id van de dag ophalen
NSString *idDagprogramma = [id objectAtIndex:plaats];
urlString = [NSMutableString stringWithFormat:#"http://zesdaagse.mobi-app.be/WCFUrl/MobileService.svc/GetDagprogrammaWedstrijden?id="];
[urlString appendString:[NSString stringWithFormat:#"%#",idDagprogramma]];
url = [NSURL URLWithString:urlString];
data = [NSData dataWithContentsOfURL:url];
json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSMutableArray *idWedstrijdDagprogramma = [NSMutableArray array];
NSMutableArray *naam = [NSMutableArray array];
NSMutableArray *uur = [NSMutableArray array];
for(NSDictionary *item in json)
{
[idWedstrijdDagprogramma addObject:[item objectForKey:#"id"]];
[naam addObject:[item objectForKey:#"naam"]];
[uur addObject:[item objectForKey:#"uur"]];
}
DagprogrammaDetail = [NSMutableArray arrayWithObjects: nil];
for(int i = 0; i < json.count; i ++)
{
NSMutableString *lijn =[NSMutableString stringWithFormat:#"%#", [naam objectAtIndex:i]];
[lijn appendString:[NSMutableString stringWithFormat:#"%s", "\t \t"]];
[lijn appendString:[NSMutableString stringWithFormat:#"%#", [uur objectAtIndex:i]]];
[DagprogrammaDetail addObject:lijn];
}
}
//methode om aantal items te weten van de array
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [DagprogrammaDetail count];
}
//methode om een item aan een index te koppelen en zichtbaar te maken
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"MenuDetailCell";
UITableViewCell *cell = [self.tableDagprogrammaDetail dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
cell.textLabel.numberOfLines = 1;
cell.textLabel.text = [DagprogrammaDetail objectAtIndex:indexPath.row];
return cell;
}

I'm very confused right know, so you know how to fix it? Cus in other
view controllers it works fine and it's same code and methods. What
should i do?
Calm Down and Recheck your Code again. I guaranteed that it'll be some silly mistake. It may happens to anyone when you are frustrated.
Things you can do :
1) NSLog your numberOfRowsInSection. Note that , If it's "0" then your cellForRowAtIndexPath is never going to be called.
2) If you are using your UITableView inside some UIView then you should add :
[self.view addSubview:table];
3) Don't Forget to include :
#interface yourViewController : UIViewController<UITableViewDataSource,UITableViewDelegate>

I Just Changed Little-bit in ViedDidLoad and its working fine
- (void)viewDidLoad
{
[super viewDidLoad];
self.navigationItem.title = menuNaam;
NSArray *dagarray = [menuNaam componentsSeparatedByString:#" "];
NSString *plaatsString = [dagarray objectAtIndex:1];
plaatsString = [plaatsString stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
//object ophalen
NSMutableString *urlString = [NSMutableString stringWithFormat:#"http://zesdaagse.mobi-app.be/WCFUrl/MobileService.svc/GetDagprogramma"];
NSURL *url = [NSURL URLWithString:urlString];
NSData *data = [NSData dataWithContentsOfURL:url];
NSError *error;
NSMutableDictionary *json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSMutableArray *idss = [[NSMutableArray alloc]init];;
NSLog(#"Json Data =%#",json);
for(NSDictionary *item in json)
{
[idss addObject:[item objectForKey:#"id"]];
}
int plaats = [plaatsString intValue];
plaats -= 1;
//id van de dag ophalen
NSString *idDagprogramma = [idss objectAtIndex:0];
urlString = [NSMutableString stringWithFormat:#"http://zesdaagse.mobi-app.be/WCFUrl/MobileService.svc/GetDagprogrammaWedstrijden?id="];
[urlString appendString:[NSString stringWithFormat:#"%#",idDagprogramma]];
url = [NSURL URLWithString:urlString];
data = [NSData dataWithContentsOfURL:url];
json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSMutableArray *idWedstrijdDagprogramma = [NSMutableArray array];
NSMutableArray *naam = [NSMutableArray array];
NSMutableArray *uur = [NSMutableArray array];
for(NSDictionary *item in json)
{
[idWedstrijdDagprogramma addObject:[item objectForKey:#"id"]];
[naam addObject:[item objectForKey:#"naam"]];
[uur addObject:[item objectForKey:#"uur"]];
}
DagprogrammaDetail = [[NSMutableArray alloc]init];
for(int i = 0; i < json.count; i ++)
{
NSMutableString *lijn =[NSMutableString stringWithFormat:#"%#", [naam objectAtIndex:i]];
[lijn appendString:[NSMutableString stringWithFormat:#"%s", "\t \t"]];
[lijn appendString:[NSMutableString stringWithFormat:#"%#", [uur objectAtIndex:i]]];
[DagprogrammaDetail addObject:lijn];
}
}

There is no way for us knowing what is going on if you won't post your full code. Obviously you missed something. Follow this step by step tutorial against your code to find where your problem hides.

Answer 4

I think your problem is with UITableViewDataSource protocol. There is method called :
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
You don't have to implement this method, because by default it returns 0. So if you implement this method and this method returns 0, you got problem. As you don't have any section, your datasource methods to create a row never gets called because you don't have any section in your tableview.
To make it work, either you don't implement
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
method at all, or it has to return at least 1.
