iphone - Open Instagram only in UIDocumentInteractionController -


my application required post image instagram, used uidocumentinteractioncontroller open image file saved in documents directory extension .igo. set com.instagram.exclusivegram uidocumentinteractioncontroller's uti property. worked fine, problem when use

[dic presentopeninmenufromrect:cgrectzero inview:self.view animated:yes];

to open uidocumentinteractioncontroller, shows pdf reader, dropbox etc. have hide other options instagram or show instagram only. , how identify cancel button press in presented menu.

  1. why uidocumentinteractioncontroller showing other options?

    if you're using code snippet internet, make sure implemented delegate method correctly.

    -(uidocumentinteractioncontroller *)setupcontrollerwithurl:(nsurl *)fileurl                                               usingdelegate:(id<uidocumentinteractioncontrollerdelegate>) interactiondelegate  {     // if you're creating new instance here,     // make sure set properties correctly     uidocumentinteractioncontroller *interactioncontroller = [uidocumentinteractioncontroller interactioncontrollerwithurl:fileurl];     // remember set again here     interactioncontroller.uti = @"com.instagram.exclusivegram";     interactioncontroller.delegate = interactiondelegate;         return interactioncontroller; }
