Modified code for opening a pdf file 
#import "ViewController.h"
@interface ViewController ()<UIDocumentInteractionControllerDelegate>
@property (strong, nonatomic) UIDocumentInteractionController *controller;
@end

@implementation ViewController
- (IBAction)openDocument:(id)sender {

NSURL *URL = [[NSBundle mainBundle] URLForResource:@"typo_tips" withExtension:@"pdf"];
self.controller = [UIDocumentInteractionController interactionControllerWithURL:URL];
self.controller.delegate = self;
self.controller.UTI = @"com.adobe.pdf";
