如何在iBooks上打开文件 [英] How to open a file on iBooks

问题描述

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：

How can I open a book on iBooks? I tried the following code, that works, but asks the user to choose an application to open the file:

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上打开，而无需询问用户。

I want it to open directly on iBooks, without asking the user for this.

任何提示？

推荐答案

只需使用此

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

其中stringUrl是你的 filePath ，其中 itms-books：开头

Where stringUrl is your filePath, with itms-books: at the beginning
