[ios] 네비게이션 바 rightbaritem 이미지 버튼 버그 iOS 11

이 코드는 ios10에서 정상적으로 작동합니다. 나는 내 레이블과 사용자 사진 프로필 인 이미지 버튼을 얻습니다. 원형 원형 .. ok. 하지만 xcode 9 ios11 시뮬레이터를 실행할 때 나는 그것을 벗어났습니다. 버튼 프레임은 32×32이어야합니다. sim을 확인하고보기를 가져오고 xcode에보기를 설명하도록 지시 할 때 170×32 또는 그와 같은 출력을 얻습니다.

여기 내 코드입니다.

let labelbutton = UIButton( type: .system)
    labelbutton.addTarget(self, action:#selector(self.toLogin(_:)), for: .touchUpInside)
    labelbutton.setTitleColor(UIColor.white, for: .normal)
    labelbutton.contentHorizontalAlignment = .right
    labelbutton.titleLabel?.font = UIFont.systemFont(ofSize: 18.00)



    let button = UIButton(type: .custom)
     button.addTarget(self, action:#selector(self.toLogin(_:)), for: .touchUpInside)
     button.frame = CGRect(x: 0, y: 0, width: 32, height: 32)
     button.setTitleColor(UIColor.white, for: .normal)
     button.setTitleColor(UIColor.white, for: .highlighted)


    var buttomItem : UIBarButtonItem = UIBarButtonItem()
    buttomItem.customView = button
    buttomItem.target = self
    buttomItem.action = "ToLogin"

    var labelItem : UIBarButtonItem = UIBarButtonItem()
    labelItem.customView = labelbutton
    labelItem.target = self
    labelItem.action = "ToLogin"


    if let user = PFUser.current() {
        print("LOGIN : checkiando si existe usuario ")
            labelbutton.setTitle(USERNAME, for: UIControlState.normal)
            labelbutton.sizeToFit()

        if(user["profile_photo_url"] != nil) {
            print(" ENCONTRO PROFILE PHOTO URL NOT NIL Y ES \(user["profile_photo_url"])")
            let photoURL = user["profile_photo_url"] as! String
            let a = LoginService.sharedInstance
            a.downloadImage(url: photoURL, complete: { (complete) in

                if (complete) {

                    button.setImage(LoginService.sharedInstance.profile_photo! , for: UIControlState.normal)

                    button.layer.cornerRadius = 0.5 * button.bounds.size.width
                   // button.imageView!.contentMode = .scaleAspectFit
                   // button.imageView!.frame = CGRect(x: 0, y: 0, width: 40, height: 40)
                    //button.imageView!.contentMode = .scaleAspectFit
                    //button.imageView!.clipsToBounds = true
                    //button.imageView!.layer.cornerRadius = 60
                    button.clipsToBounds = true
                    self.NavigationItem.rightBarButtonItems = [buttomItem,labelItem]
                }


            })
        } else {
                self.NavigationItem.rightBarButtonItem = labelItem

        }
            print(" EL FRAME DEL BUTTON ES \(button.frame)")

    } else {

        labelbutton.setTitle("Login", for: UIControlState.normal)
        labelbutton.sizeToFit()
        self.NavigationItem.rightBarButtonItem = labelItem

    }
