Firstly, save a built in pdf file in document Directory of iPhone Simulator (say it demo.pdf). then use following code in ViewController.m file at ViewDidLoad method and dont forget to add UIWebViewDelegate in ViewController.h file

    -(void) viewDidLoad
    {
           [super viewDidLoad];
           UIWebView theWebView=[[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];
           theWebView.delegate=self;
           theWebView.scalesPageToFit=YES;
           [self.view addSubview:theWebView];

           NSArray *paths=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
           NSString *documentDir=[paths objectAtIndex:0];
           NSString *fileName=[documentDir stringByAppendingPathComponent:@"demo.pdf"];
           NSURL *url=[NSURL fileURLWithPath:fileName];
           [theWebView loadRequest:[NSURLRequest requestWithURL:url]];
     }
