UIDocumentInteractionController Delegate

code:

-(nsurl*)loaddocument:(nsstring*)docname docextension:(nsstring*)docext  {      nsstring *path = [[nsbundle mainbundle] pathforresource:docname oftype:docext];      return [nsurl fileurlwithpath:path];  }

code:

- (ibaction)toolbaractionbuttonpressed:(id)sender {      uidocumentinteractioncontroller *dicontroller = [uidocumentinteractioncontroller interactioncontrollerwithurl:[self loaddocument:[currentcontent objectforkey:@"docname"] docextension:[currentcontent objectforkey:@"docextension"]]];      [dicontroller presentopeninmenufrombarbuttonitem:sender animated:yes];  }

when pressing toolbaractionbutton, action sheet presents 1 or more buttons, depending on device app running on (and if apps support document installed). instance, on primary device, options open in ibooks, adobe reader, , kindle app appear.

however, when select of these action sheet index buttons, action sheet dismisses , nothing happens.

delegate method need implement working? understand following delegate method candidate, how call application identifiers?

code:

- (void) documentinteractioncontroller: (uidocumentinteractioncontroller *) controller willbeginsendingtoapplication: (nsstring *) application {  }
