I'm new in iOS. I want to add PDF document in iOS. I try two options. URL and Document in iOS. But When I try open PDF with URL I get empty page. When I try with pdf document I get error on Xcode.

I try this for URL

CGRect rect = [[UIScreen mainScreen] bounds];
CGSize screenSize = rect.size;

UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(10, 10, 200, 200)];

NSURL *targetURL = [NSURL URLWithString:@"http://dokuman.osym.gov.tr/pdfdokuman/2012/OSYS/2012YGSSorular.pdf"];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
[webView loadRequest:request];

I try this one for document

NSString *path = [[NSBundle mainBundle] pathForResource:@"document" ofType:@"pdf"];
NSURL *targetURL = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
[webView loadRequest:request];

Is it about storyboard? Because I dont use .xib

I get this error.

I copy pasted your code, and it works fine for me. Did you make sure to [self.view addSubview:webView] ? And double check your internet connection. Also it's a 52 page document, so on a slow connection it might take a while to load. – SethHB
Definitely share the error. – noobzilla
Waited 2 hours but It did not work. Is it about .storyboard? Because I dont use .xib. – Ozgur

Yes Ozgur it is to do with your storyboard - "'Push segues can only be used when the source controller is managed by an instance of UINavigationController."

It tells you what the problem is - you are using a segue of type push which is trying to push a destination view controller when the source view controller is not a UINavigationController. Change the type of the segue or change the type of the source view controller, whichever is most appropriate for your GUI design.
