The documentation says that UIDocumentInteractionController allows to open file implicitly (UTI property is nil) with installed apps but not native. 

```
UIDocumentInteractionController *controller = [UIDocumentInteractionController  interactionControllerWithURL:fileURL];
[controller retain];
controller.delegate = self;
//controller.UTI = uti;

CDVViewController* cont = (CDVViewController*)[ super viewController ];
CGRect rect = CGRectMake(0, 0, cont.view.bounds.size.width, cont.view.bounds.size.height);
[controller presentOpenInMenuFromRect:rect inView:cont.view animated:YES];

```

Is it possible to open for example pdf file in Safari or image in gallery?

P.S. I am new in Objective C :)
