title: It is possible to have numberOfSectionsInTableView dynamically?
body: <p>Can I have the number of rows dynamically?
  I'm trying to remove a tableView section header and I don'k know how... and I've taught that a solution would be to change the number of sections.</p>
  
  <p>Right now my numberOfSectionsInTableView looks like:</p>
  
  <pre><code>-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
          return 2;
  }
  </code></pre>
  
  <p>and</p>
  
  <pre><code>-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
  
      beTribesAppDelegate *appDelegate = [UIApplication sharedApplication].delegate;
  
      switch (section) {
          case 0:
              return [appDelegate.firstArray count];
          case 1:
              return [appDelegate.secondArray count];    
          default:
              return 0;
      }
  }
  </code></pre>
  
  <p>setting the title section like this:</p>
  
  <pre><code>- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
  { 
      sectionTitles = [[NSMutableArray alloc] init];
  
          [sectionTitles addObject:@"firstSection"];
          [sectionTitles addObject:@"secondSection"];
      NSString *sectionText = [sectionTitles objectAtIndex:section];
      return sectionText;
  }
  </code></pre>
