ios - Setting images of a button -


i have come across issue cannot resolve.

i have struct , change image of button in each collection view. text/image works according plan. however, when trying change image button struggling. please me?

class collectionviewcontent{      var caption = ""     var mainimage: uiimage!     var userprofileimage : uibutton       init(caption: string, mainimage: uiimage!, userprofileimage : uibutton! )     {         self.description = description         self.mainimage = featuredimage         self.userprofileimage = posteduserprofileimage     }       static func  showposts() -> [posts]     {         return [             posts(description: "sweet", mainimage: uiimage(named: "image 1"), posteduserprofileimage:!),                    posts(description: "awesome", mainimage: uiimage(named: "image 2")!),                    posts(description: "wow!", mainimage: uiimage(named: "image 3")!                    )         ]     }   }

this collectionviewcell class

class colviewcontetcollectionviewcell: uicollectionviewcell {       var posts: posts! {         didset {             updateui()          }     }     @iboutlet weak var featuredimage: uiimageview!     @iboutlet weak var postcaptionlabel: uilabel!      @iboutlet weak var posteduserprofileimage: uibutton!        func updateui() {         postcaptionlabel?.text! = posts.title         featuredimage?.image! = posts.featuredimage         posteduserprofileimage = posts.posteduserprofileimage     }      override func layoutsubviews() {         super.layoutsubviews()          self.layer.cornerradius = 10.0         self.clipstobounds = true     }  }

i think line of code incorrect way, not sure.

 posteduserprofileimage = posts.posteduserprofileimage

instead of:

posteduserprofileimage = posts.posteduserprofileimage

you should do:

posteduserprofileimage.setimage(posts.posteduserprofileimage.image(for: uicontrolstate.normal), for: uicontrolstate.normal)

since posteduserprofileimage uibutton, need use setimage method set it's image control specific control state. if no images set other control states, image normal state used others too.

and since posts.posteduserprofileimage uibutton (as mentioned in comments below) need button's image via image(for:) method.
