i have app configured pdfs in other applications such mail, can hold down on pdf , have open "open in" app; have working , app opens, want display document in app, how do that? pretty sure have use appdelegate, started using swift , lost , cannot find tutorial helps task, appreciated.

appdelegate.swift

class appdelegate: uiresponder, uiapplicationdelegate {

var window: uiwindow? let uiapplicationlaunchoptionsurlkey: string = ""  func application(application: uiapplication, didfinishlaunchingwithoptions launchoptions: [nsobject: anyobject]?) -> bool {     if uiapplicationlaunchoptionsurlkey.isempty {         print("string empty.")     }     else{      let alertview:uialertview = uialertview()     alertview.title = "pdf upload"     alertview.message = "??"     alertview.delegate = self     alertview.addbuttonwithtitle("ok")     alertview.show()     }     return true }

in appdelegate's didfinishlaunchingwithoptions, can handle setting ui display pdf. can use uiwebview render document.
