Question

如何在iBooks上打开书？我尝试了以下代码，但有效，但要求用户选择一个应用程序来打开文件：

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];

我希望它能直接在iBooks上打开，而不会向用户询问。

任何提示？

只需使用此

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

其中stringUrl是您的filePath，开头是itms-books:
