Multitasking in iphone
How to implement the multitasking where to open the other application from my application (for example: opening my PDF document开发者_运维技巧 in to the iBooks app)?
See the documentation for UIDocumentInteractionController
. It offers the functionality to give the user a preview of a document and present her with a list of apps in which she can open this document.
AFAIK it is not possible to send a PDF to iBooks programmatically without user interaction.
