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
