numberofRowsinSection can it return the VALUES of NSMutableArray?

Is that possible to return as number of rows in section the value(and not the count) of an NSMutableArray

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    NSLog(@"number of rows in section: %@",[arrayofNombre objectAtIndex:section]);//it prints the right value
    return [arrayofNombre objectAtIndex:section];
}

The application just crashes, and when I put a constant value (return 2 for example), the application runs but it gives not the expected result. I'm surely missing something. Thank you for helping.

If your array holds instances of NSNumber you need to convert the object to NSInteger:

return [[arrayofNombre objectAtIndex:section] integerValue];

It seems that you're returning an NSNumber, while the method is expecting an NSInteger. You should convert the NSNumber as follows.

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    NSLog(@"number of rows in section: %@",[arrayofNombre objectAtIndex:section]);//it prints the right value
    return [[arrayofNombre objectAtIndex:section] intValue];
}

No. You are returning an NSInteger. You need to explicitly declare a property to hold the value if you choose.
