Answer 1

try this.
NSString *strPath = [[NSBundle mainBundle]pathForResource:#"Insupen_User_Guide" ofType:#"pdf"];
[catalogue loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[strPath stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]]];
maybe this will help you.

NSString *path = [[NSBundle mainBundle]pathForResource:#"HR" ofType:#"pdf"];
NSURL *targeturl = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:targeturl];
// _webview = [[UIWebView alloc]init];
[[_webview scrollView] setContentOffset:CGPointMake(0, 500) animated:YES];
[_webview stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:#"window.scrollTo(0.0, 50.0)"]];
[_webview loadRequest:request];
// worked for me perfectly you can try this

In the code you posted you are turning the contents of the PDF file into a UTF8 encoded string and displaying the string inside the web view, this is not what you want.
Instead, you need to make a NSURLRequest pointing to the local PDF and load the request in the web view like so
NSString *pdfPath = [[NSBundle mainBundle] pathForResource:#"Insupen_User_Guide" ofType:#"pdf"];
NSURL *pdfUrl = [NSURL fileURLWithPath:pdfPath];
NSURLRequest *pdfUrlRequest = [NSURLRequest requestWithURL:pdfUrl];
[catalogue loadRequest:pdfUrlRequest];

You can also display PDF in UIDocumentInteractionController using this.
UIDocumentInteractionController *docController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"PDF file name" ofType:#"pdf"]]];
docController.delegate = self;
//[DocView addSubview:docController];
[docController presentPreviewAnimated:YES];
And add these delegate methods in your class.
#pragma mark documentInteractionController methods
- (UIViewController *)documentInteractionControllerViewControllerForPreview:(UIDocumentInteractionController *)controller {
return self;
}
- (UIView *)documentInteractionControllerViewForPreview:(UIDocumentInteractionController *)controller {
return self.view;
}
- (CGRect)documentInteractionControllerRectForPreview:(UIDocumentInteractionController *)controller {
return self.view.frame;
}
- (BOOL)documentInteractionController:(UIDocumentInteractionController *)controller canPerformAction:(SEL)action{
return FALSE;
}
