Open .ibooks file automatically from iOS application (Swift) - ios

Question

I want to open specific file in iBooks App. I'm using UIDocumentsIntractionController to send this file to iBooks App. My code:
class ViewController : UIViewController {
...
...
#IBOutlet var iBooksBtn: UIButton!
#IBAction func book(sender: AnyObject) {
let ibookPath = NSBundle.mainBundle().pathForResource("test1",ofType: "ibooks")!
interactionController = UIDocumentInteractionController(URL: NSURL(fileURLWithPath:ibookPath))
interactionController.UTI = "com.apple.ibooks"
interactionController.presentOpenInMenuFromRect(CGRectZero,inView:self.iBooksBtn, animated:false)
}
...
...
}
So, for now i store this file in mainBundle, but in future i want to download it from the Internet. So when i press button, i got few results to
choose:
But i want to open this file ONLY with iBooks and without requests to choose App (as on picture). As far as i know i need to use UTI for *.ibooks file, i guess UTI, that i used is wrong. Thanks for any help. Also custom URL scheme (ibooks:// and etc.) is not working for me.

Answer 1

To open iBooks you should use custom URL scheme:
To open the library:
NSString *stringURL = #"ibooks://";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];
To open the iBooks store at a particular book page, you have to add the complete URL to that particular book:
NSString *stringURL = #"itms-books://itunes.apple.com/de/book/marchen/id436945766";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];
NSString *stringURL = #"itms-bookss://itunes.apple.com/de/book/marchen/id436945766";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];
