UIWebView difference between iOS 4 and iOS 5 when reading a pdf file

I found the difference between iOS 4 and iOS 5 that caused an error in my code. When I create UIWebView, he also created a subview called UIWebBrowserViewwith a frame size of 577 x 533. Then I load the PDF file into UIWebView, and here it is different from iOS 4 and 5. In iOS 4, when the processing reaches the method "webViewDidFinishLoad:", UIWebBrowserViewit still exists with a frame of 577 x 2947 (pdf size, I suppose), but in iOS 5 it UIWebBrowserViewno longer exists and place it there UIWebPDFViewwith a frame of 577 x 533 (here I expected a frame of 577 x 2947). Finally, I trigger the event and views as I expected ( UIWebBrowserViewwith a 577 x 2947 frame in iOS 4 and UIWebPDFViewwith a 577 x 2947.4 frame in iOS 5).

The problem is that when loading the pdf file, when the processing reaches the "webViewDidFinishLoad:" method, I would like to put notes in the PDF file, but this method UIWebPDFViewdoes not yet have a real PDF size. If I just put notes, they will not appear. On iOS 4, it worked, but on iOS 5, it no longer works. Can anyone help on how I can put notes in a web view upload?

Here is the code that shows the different behavior of iOS and below the log.

ViewController.h
#import <UIKit/UIKit.h>

@interface ViewController : UIViewController <UIWebViewDelegate, UIGestureRecognizerDelegate>
{
    IBOutlet UIView *view;
    IBOutlet UIWebView * webView;
}

- (void)handleTap:(UITapGestureRecognizer *)recognizer;

@end

ViewController.m
#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    [webView setUserInteractionEnabled:YES];
    [view bringSubviewToFront:webView];

    //Load view with a pdf file
    NSString *path = [[NSBundle mainBundle] pathForResource:@"pdf_teste" ofType:@"pdf"];
    NSData *pdfData = [NSData dataWithContentsOfFile:path];
    [webView loadData:pdfData MIMEType:@"text/pdf" textEncodingName:@"UTF-8" baseURL:[NSURL URLWithString:@""]];

    //Log
    NSLog(@"On viewDidLoad: %@", [[webView viewForZoomingInScrollView:(UIScrollView *)[[webView subviews] objectAtIndex:0]] description]);

    //Add a tap gesture recognizer
    UITapGestureRecognizer *recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];
    recognizer.delegate = self;
    [webView addGestureRecognizer:recognizer];
}

- (void)webViewDidFinishLoad:(UIWebView *)view
{
    //Log
    NSLog(@"On webViewDidFinishLoad: %@", [[webView viewForZoomingInScrollView:(UIScrollView *)[[webView subviews] objectAtIndex:0]] description]);

    //I’d like to insert the saved notes here.

}

- (void)handleTap:(UITapGestureRecognizer *)recognizer
{
    //Log
    NSLog(@"On Tap Event: %@", [[webView viewForZoomingInScrollView:(UIScrollView *)[[webView subviews] objectAtIndex:0]] description]);
}

@end
