open iBooks from my app
I have some PDF in my app. I want to provide an option to open those PDF in other third party e-readers app that might be installed on the device, like Stanza and iBooks. Dropbox application has successfully implemented this feature and I can't find any information on how to detect what other e-readers are available on the device or what the custom url scheme is for those apps. Any hel开发者_运维技巧p would be greatly appreciated. thanks in advance guys.
iBooks
NSString *stringURL = @"itms-books:";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];
NSString *stringURL = @"itms-bookss:";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];
First of all you will need to create a NSURL object like so:
NSURL *url = [NSURL fileURLWithPath:file.FileName];
file.FileName --> your local file path where the document is stored in the local db.
UIDocumentInteractionController *docController = [UIDocumentInteractionController interactionControllerWithURL:url];
docController.delegate = self;
[docController retain];
[docController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES];
The following delegate methods will need to be implemented:
-(void)documentInteractionController:(UIDocumentInteractionController *)controller willBeginSendingToApplication:(NSString *)application
{
}
- (void)documentInteractionController:(UIDocumentInteractionController *)controller didEndSendingToApplication:(NSString *)application
{
}
- (void)documentInteractionControllerDidDismissOpenInMenu:(UIDocumentInteractionController *)controller
{
}
You don't need to detect the other apps, you need to know the url that can open them.
A call like this:
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.apple.com"]];
Tells the phone to open the page in whatever app handles http/html requests which is safari. iBooks has their own url format which hopefully you can track down.
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"ebook://iRobot.pdf"]];
NOTE: that's not correct, just meant to illustrate a different url scheme.
