Table and Array

Question

I have problem with TableView its empty.

In (.h) file:

@interface TableViewController : UITableViewController{

NSMutableArray *coursArray; }

In (.m) file:

In viewDidLoad

[coursArray addObject:[[NSMutableDictionary alloc]initWithObjectsAndKeys:@"AR111",@"courseCode",@"Arabic Communication Skills (I)",@"courseName", nil]];
[coursArray addObject:[[NSMutableDictionary alloc]initWithObjectsAndKeys:@"AR112",@"courseCode",@"Arabic Communication Skills (II)",@"courseName", nil]];

and in numberOfRowsInSection

return [coursArray count];

and in cellForRowAtIndexPath

cell.textLabel.text = [[coursArray objectAtIndex:indexPath.row]objectForKey:@"courseCode"];

So whats wrong please help me :)

are you sure that you set the delegate and the dataSource of the table correctly? — Omar Abdelhafith

Omar makes a great suggestion. You could put NSLog or debugger breakpoints at numberOfRowsInSection and cellForRowAtIndexPath and make sure they're being invoked like you think they should. — Rob

And, of course, I assume you're doing the necessary alloc and init of coursArray itself (e.g. coursArray = [[NSMutableArray alloc] init]), too, in viewDidLoad, too, because you're not showing that here. — Rob

Yes, if I use cell.textLabel.text = @"Yes"; with numberOfRowsInSection return 2; its work. — Hesham Saeed

Very good. Just make sure to do the necessary alloc and init of coursArray itself in viewDidLoad, too, e.g.

coursArray = [[NSMutableArray alloc] init]
