我MessageKit在Chat我的App.
在ChatViewController其中我以编程方式创建我添加rightBarButtonItem了user picture. 我想添加funcUserProfileViewController如果其他用户点击，它将被重定向rightBarButtonItem。
现在看起来像这样。用户图片专用蓝色带箭头。
现在我有这个代码：
class ChatsViewController: MessagesViewController {
override func viewDidLoad() {
super.viewDidLoad()
maintainPositionOnKeyboardFrameChanged = true
messageInputBar.sendButton.setImage(#imageLiteral(resourceName: "send"), for: .normal)
messageInputBar.sendButton.title = nil
messageInputBar.inputTextView.placeholder = NSLocalizedString("New message", comment: "Новое сообщение")
messageInputBar.delegate = self
messagesCollectionView.messagesDataSource = self
messagesCollectionView.messagesLayoutDelegate = self
messagesCollectionView.messagesDisplayDelegate = self
messagesCollectionView.messageCellDelegate = self
}
private func loadChat(channel: Channel) {
guard let id = channel.id else {
navigationController?.popViewController(animated: true)
return
}
reference = db.collection([FSCollections.chats, id, "thread"].joined(separator: "/"))
messageListener = reference?.addSnapshotListener { querySnapshot, error in
guard let snapshot = querySnapshot else {
print("Error listening for channel updates: \(error?.localizedDescription ?? "No error")")
return
}
if UserDefaults.standard.bool(forKey: UserDefaultsKeys.switcherIsClick) == true {
self.navigationItem.title = self.channel?.recipientName ?? ""
} else {
self.navigationItem.title = self.channel?.name ?? ""
}
self.configurePhotoProfile()
snapshot.documentChanges.forEach { change in
self.handleDocumentChange(change)
}
}
}
func configurePhotoProfile() {
let imageView = UIImageView()
let widthConstraint = imageView.widthAnchor.constraint(equalToConstant: 34)
let heightConstraint = imageView.heightAnchor.constraint(equalToConstant: 34)
let tap = UITapGestureRecognizer(target: self, action: #selector(ChatsViewController.didTapImageButton(_:)))
tap.numberOfTouchesRequired = 1
heightConstraint.isActive = true
widthConstraint.isActive = true
imageView.kf.setImage(with: URL(string: channel?.recipientUrlImage ?? ""))
imageView.backgroundColor = .clear
imageView.layer.masksToBounds = true
imageView.layer.cornerRadius = 17
imageView.isUserInteractionEnabled = true
imageView.addGestureRecognizer(tap)
if UserDefaults.standard.integer(forKey: UserDefaultsKeys.selectedSegmentedControl) == 0 {
self.navigationItem.rightBarButtonItem = UIBarButtonItem(customView: imageView)
} else {
self.navigationItem.rightBarButtonItem = nil
}
}
@objc func didTapImageButton(_ sender: UIBarButtonItem) {
if let detailPhotographerVC = storyboard?.instantiateViewController(withIdentifier: "detailPhotographerVC") as? DetailPhotographerViewController {
detailPhotographerVC.id = channel?.recipientID ?? ""
let backItem = UIBarButtonItem()
backItem.title = ""
self.navigationItem.backBarButtonItem = backItem
self.navigationController?.pushViewController(detailPhotographerVC, animated: true)
} else {
print("error")
}
}
}
因此，如果用户点击user picture我会在控制台中从func didTapImageButton.
我不明白为什么会出现错误...在detailPhotographerVC我重定向正确id并且detailPhotographerVC不能接受除 id 之外的任何数据。
UPD。
我尝试更新我的代码func didTapImageButton：
@objc func didTapImageButton(_ sender: UIBarButtonItem) {
let detailPhotographerVC = storyboard!.instantiateViewController(withIdentifier: "detailPhotographerVC") as! DetailPhotographerViewController
detailPhotographerVC.id = channel?.recipientID ?? ""
let backItem = UIBarButtonItem()
backItem.title = ""
self.navigationItem.backBarButtonItem = backItem
self.navigationController?.pushViewController(detailPhotographerVC, animated: true)
}
但再次出现错误，请检查屏幕截图。
