ios - Calling share sheet from UIView -

trying wrap head around issue i'm facing. want press button , share url via share sheet. here have far:

import uikit class sidemenu: uiview {     //share app      @ibaction func shareappbtn(sender: anyobject ) {         print("shareappbtn tapped")         let mywebsite = nsurl(string:"http://www.google.com/")         guard let url = mywebsite else {             print("nothing found")             return         }               let shareitems:array = [url]         let activityviewcontroller:uiactivityviewcontroller = uiactivityviewcontroller(activityitems: shareitems, applicationactivities: nil)         self.presentviewcontroller(activityviewcontroller, animated: true, completion: nil)      } } 

which gave me following error: value of type 'sidemenu' has no member 'presentviewcontroller'. think above doesn't work because presentviewcontroller component of uiviewcontroller , i'm calling uiview.

so instead tried following, attempting call uiviewcontroller:

import uikit class sidemenu: uiview { //share app  @ibaction func shareappbtn(sender: anyobject, viewcontroller : uiviewcontroller) -> void {     print("shareappbtn tapped")     let mywebsite = nsurl(string:"http://www.google.com/")     guard let url = mywebsite else {         print("nothing found")         return     }     let shareitems:array = [url]     let activityviewcontroller:uiactivityviewcontroller = uiactivityviewcontroller(activityitems: shareitems, applicationactivities: nil)     viewcontroller.presentviewcontroller(activityviewcontroller, animated: true, completion: nil)      } } 

but above gave me following error: unrecognized selector sent instance 0x7fe93acb6720'.

so tried with:

import uikit class sidemenu: uiview { //share app  @ibaction func shareappbtn(sender: anyobject) {     print("shareappbtn tapped")     let mywebsite = nsurl(string:"http://www.google.com/")     guard let url = mywebsite else {         print("nothing found")         return     }     let shareitems:array = [url]     let activityviewcontroller:uiactivityviewcontroller = uiactivityviewcontroller(activityitems: shareitems, applicationactivities: nil)     self.window?.rootviewcontroller?.presentviewcontroller(activityviewcontroller, animated: true, completion: nil)     } } 

but above gave me following error:

warning: attempt present <uiactivityviewcontroller: 0x7fe03e04c600>  on <ramanimatedtabbarcontroller.ramanimatedtabbarcontroller: 0x7fe03bc4a170> presenting <sidemenu.uisidemenunavigationcontroller: 0x7fe03c094200> 

what missing here? want call share sheet on uiview.

thanks.

this working expected.. uiviews aren't supposed presenting views. should reporting delegates handle that.

in case of sidemenu, uiview, you'd need delegate handle it's doing... e.g. set view controller presents sidemenu delegate..

so using bit of example code whipped up..

protocol sidemenudelegate {      func sidemenudidshare()  } 

the delegate protocol view controller handles sidemenu view implement.

class sidemenu: uiview {     var delegate: sidemenudelegate? } 

in sidemenu view class, you'd add delegate property.

class sidemenuviewcontroller: uiviewcontroller, sidemenudelegate {      func sidemenudidshare() {         print("this share code goes , can present other viewcontrollers from")     }      override func viewdidload() {         super.viewdidload()          let sidemenu = self.view as? sidemenu         sidemenu?.delegate = self      }  } 

in view controller handles sidemenu, you'd implement sidemenudelegate protocol e.g. class sidemenuviewcontroller: uiviewcontroller, sidemenudelegate

doing allows sidemenu tell it's delegate (the viewcontroller) when happens, in case, implemented func sidemenudidshare().
