J'ai un headerView dans lequel j'ai un bouton flottant. Puisque tous les sous-éléments du bouton float sont générés par programme et qu'il s'agit d'une sous-vue de headerView, je ne peux pas appeler performSegue
. J'ai essayé de créer une méthode de délégué, mais j'ai complètement foiré. Je sais que les protocoles pourraient être la solution, mais je ne suis pas sûr de la façon de le faire. Je joins l'image du headerView ci-dessousPerformSegue à partir du bouton personnalisé UICollectionReusableView (En-tête) Swift
Code headerView:
class ProfileHeader: UICollectionReusableView, FloatyDelegate {
@IBOutlet weak var pname: UILabel!
@IBOutlet weak var pusername: UILabel!
@IBOutlet weak var profilePic: UIImageView!
@IBOutlet weak var userDesc: UILabel!
@IBOutlet weak var allviews: UILabel!
@IBOutlet weak var allphotos: UILabel!
var user : User!
var userposts = [String]()
var currentViewUser: String!
var floaty = Floaty()
let uid = KeychainWrapper.standard.string(forKey: KEY_UID)
override func awakeFromNib() {
super.awakeFromNib()
user = User()
fetchCurrentUser()
profilePic.addBlackGradientLayer(frame: profilePic.bounds)
layoutFAB()
}
func layoutFAB() {
floaty.openAnimationType = .slideDown
floaty.hasShadow = false
floaty.addItem("Edit Profile", icon: UIImage(named: "")) { item in
// here is where the segue is to be performed.
}
floaty.paddingY = (frame.height - 50) - floaty.frame.height/2
floaty.fabDelegate = self
floaty.buttonColor = UIColor.white
floaty.hasShadow = true
floaty.size = 45
addSubview(floaty)
}
func fetchCurrentUser(){
if uid != nil {
FBDataservice.ds.REF_CURR_USER.observeSingleEvent(of: .value, with: { (snapshot) in
if let allData = snapshot.value as? Dictionary<String, Any> {
if let cred = allData["credentials"] as? Dictionary<String, Any> {
let user = User(userid: snapshot.key, userData: cred)
self.pusername.text = user.username
self.pname.text = user.name
self.userDesc.text = user.aboutme
self.allphotos.text = String(user.photos)
self.allviews.text = String(user.views)
if user.userPic != nil {
let request = URL(string: user.userPic)
Nuke.loadImage(with: request!, into: self.profilePic)
} else {
return
}
}
}
})
}
}
}
