Method returning no of rows in a section

i want to do something like this
in detailviewcontroller.m
it is the 2nd view controller
this is pseudo code I am weak in OOP concepts so appologies
- (void)viewDidLoad
{
NSMutableArray * contentsfromprevious = [[NSMutableArray alloc]initWithCapacity:0];
Preface * data = [[Preface alloc]init];
data.preface_url = contentsfromprevious;
data = preface_contents;
[self.loadwebview.request];
}

First of all your question is still not clear enough. What I've come to understand that, you want something like this:
In the MasterViewController you wish show a list of your links (html pages stored locally).
If any of the table view cells are tapped, you want to display the locally stored html page in a web view on the DetailViewController.
Assuming this, you should implement this UITableViewDelegate method on your MasterViewController:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
DetailViewController *detailVC = [[DetailViewController alloc] initWithNibName:#"DetailViewController" bundle:nil];
detailVC.htmlFileName = [htmlFiles objectAtIndex:indexPath.row]; // you might need to change this according to your need, as I said your requirement is unclear
[self.navigationController pushViewController: detailVC animated:YES];
}
Also you'll need to add this into your DetailViewController.h file
#property (nonatomic, strong) NSString *htmlFileName;
And after you've done this, you should change your DetailViewControllers viewDidLoad method into something like this:
- (void)viewDidLoad
{
// your code
// ....
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource: htmlFileName ofType:#"html"] isDirectory:NO]]];
webView.scalesPageToFit = YES;
// your code
// ...
}
I am not sure if this is what you really want though. On the other note, you don't have to put break statements after any return statements. It never gets executed.
