Zoom in on webview on appearing

I have a UIWebView that loads a PDF that is setup in landscape format and is very hard to read on the iPhone screen. My code is like this:

- (void)viewWillAppear:(BOOL)animated {
NSURL *url = [NSURL URLWithString:_entry.articleUrl];   
NSLog(@"%@",url);
[_webView loadRequest:[NSURLRequest requestWithURL:url]];
self.title = _entry.articleTitle;
timer = [NSTimer scheduledTimerWithTimeInterval:(1.0/2.0) target:self selector:@selector(tick) userInfo:nil repeats:YES];

}

What are some ways I could set it to be zoomed in more and possibly moved over to the right hand side of the top pdf page?

first make sure your UIWebView has scalesPageToFit property enabled

self.myWebView.scalesPageToFit = YES;

And then in your HTML add this tag inside the 'head' tag 

<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0;">

you can make maximum-scale=1.5 if that will make it appears better.

I am not sure about if it is a PDF file how to add these tags to it. Maybe you can add the tags and implement the PDF inside the html file.

Here is how to embeded a PDF file inside HTML

<embed src="filename.pdf" width="500" height="375">

Good luck!

In IOS version less than 5:

 UIScrollView *sv = [[_webView subviews] objectAtIndex:0];
 [sv setZoomScale:2.0 animated:NO];// increase scale factor to zoom more

In IOS 5:

  [_webView.scrollView setZoomScale:2.0 animated:NO];// increase scale factor to zoom more

You can use content offset to move to top right hand side
