Q:

PDF in webview performance

I am using the following (simple) code to load a PDF from the documents folder in my app into a UIWebView. The performance is very poor. I tried loading the same PDF from the web via Safari and the performance was great. Does anyone have any ideas? (this viewController is being presented as a modalViewController).
- firstView.m
InfoViewController *mcontroller = [[InfoViewController alloc] init];

        NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                                             NSUserDomainMask, YES);
        NSString *docsPath = [paths objectAtIndex:0];

NSString *pathToPDF = [NSString stringWithFormat:@"%@/myPDF.PDF",docsPath];

NSURL *targetURL = [NSURL fileURLWithPath:pathToPDF];

mcontroller.urlToFile = targetURL;
[self presentModalViewController:mcontroller animated:YES];

modalViewController.m - 
- (void)viewDidLoad {
    [super viewDidLoad];

    NSURLRequest *request = [NSURLRequest requestWithURL:urlToFile];

    [webView loadRequest:request];

}

A:

I ended up using the documentInteractionController for this to display the PDF in Quick Look. There is a great tutorial for this in the 2010 WWDC vids.
No idea why it wasn't working well in webView, but it's smooth as silk in Quick Look.
