i don't know if possible wondering if there anyway can insert uiview , contents tweet or facebook post when user sends out tweet app, image of uiview displayed in tweet. appreciated. here attempt says //this line not anything:

func sendsocialpost(servicetype:string) {      if slcomposeviewcontroller.isavailableforservicetype(servicetype) {          // users device twitter         let socialdialog:slcomposeviewcontroller = slcomposeviewcontroller(forservicetype: servicetype)          socialdialog.setinitialtext("whats mood like?")          // line not         socialdialog.inputaccessoryview?.insertsubview(self.scrollviewview, abovesubview: self.contentview)          socialdialog.completionhandler = { (result:slcomposeviewcontrollerresult) in              // check if user sent tweet of cancelled             if result == slcomposeviewcontrollerresult.done {                 // user has sent social post                 nslog("post sent")             }             else if result == slcomposeviewcontrollerresult.cancelled {                 nslog("post cancelled")             }         }          // present social dialog box         self.presentviewcontroller(socialdialog, animated: true, completion: nil)      }     else {          // social account credentials haven't been added settings         if servicetype == slservicetypetwitter {             nslog("a twitter account needs set in settings app.")         }         else if servicetype == slservicetypefacebook {             nslog("a facebook account needs set in settings app.")         }      }  } 

you can capture view uiimage , tweet that.. if that's mean..

    func captureviewarea() -> uiimage {         uigraphicsbeginimagecontextwithoptions(self.viewtocapture.bounds.size, self.viewtocapture.opaque, 0.0)         self.viewtocapture.layer.renderincontext(uigraphicsgetcurrentcontext())         let viewimage = uigraphicsgetimagefromcurrentimagecontext()         uigraphicsendimagecontext()         return viewimage     }
