如何在iBooks上打開文件

Question

如何在iBooks上打開書籍？我想下面的代碼，這樣的作品，但要求用戶選擇的應用程序打開文件：

self.docController = [UIDocumentInteractionController alloc]; 

//leaves only the file name 
NSString *bookFile = @"my-book.pdf"; 

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex: 0]; 

NSString* filePath = [documentsDirectory stringByAppendingPathComponent: bookFile]; 

// Using the Book path 
self.docController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:filePath]]; 

// setting the delegate 
_docController.delegate = self; 

// open the menu only if we find a valid application that can 
// open the file 
BOOL isValid = [self.docController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES]; 

我希望它直接在iBooks的打開，不要求該用戶。

任何提示？

只是用這個

NSURL *url = [NSURL URLWithString:stringURL]; 
[[UIApplication sharedApplication] openURL:url]; 

哪裏stringUrl是你filePath，與itms-books:開頭
