自从我在这里愚弄自己已经有一段时间了,所以这里又一次又一次,因为我还在努力学习,感觉好像我正在追逐这个项目的尾巴。
话虽如此,最终我想让Jerkoch的SwipeCellKit工作,但此时没有必要,因为我只需要弄清楚除了'删除'单元格动作之外如何添加更多选项。
这就是我所拥有的:My Project
这就是我想要的:Jerkoch's Project
如果我在
的tableView上设置delegate属性,我会丢失数据let cell = tableView.dequeueReusableCell(withIdentifier: "CommentCell", for: indexPath) as! CommentTableViewCell
到
let cell = tableView.dequeueReusableCell(withIdentifier: "CommentCell", for: indexPath) as! SwipeTableViewCell
这是我的CommentViewController代码:
import UIKit
import SwipeCellKit
class CommentViewController: UIViewController {
var postId: String!
var comments = [Comment]()
var users = [User]()
override func viewDidLoad() {
super.viewDidLoad()
tableView.tableFooterView = UIView(frame: CGRect.zero)
tableView.separatorInset = UIEdgeInsets.zero
tableView.dataSource = self
tableView.estimatedRowHeight = 100
tableView.rowHeight = UITableViewAutomaticDimension
loadComments()
}
func loadComments() {
Api.Post_Comment.REF_POST_COMMENTS.child(self.postId).observe(.childAdded, with: {
snapshot in
Api.Comment.observeComments(withPostId: snapshot.key, completion: {
comment in
self.fetchUser(uid: comment.uid!, completed: {
self.comments.append(comment)
self.tableView.reloadData()
})
})
})
}
func fetchUser(uid: String, completed: @escaping () -> Void ) {
Api.User.observeUser(withId: uid, completion: {
user in
self.users.append(user)
completed()
})
}
}
extension CommentViewController: UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return comments.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "CommentCell", for: indexPath) as! CommentTableViewCell// Can't update this to SwipeTableViewCell - Will loose data
cell.selectedBackgroundView = createSelectedBackgroundView()
let comment = comments[indexPath.row]
let user = users[indexPath.row]
cell.comment = comment
cell.user = user
cell.delegate = self
return cell
}
}
extension CommentViewController: SwipeTableViewCellDelegate{
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
}
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath, for orientation: SwipeActionsOrientation) -> [SwipeAction]? {
guard orientation == .right else { return nil }
let deleteAction = SwipeAction(style: .destructive, title: "Delete") { action, indexPath in
// handle action by updating model with deletion
}
// customize the action appearance
deleteAction.image = UIImage(named: "delete")
let flagAction = SwipeAction(style: .destructive, title: "Flag") { action, indexPath in
// handle action
}
deleteAction.image = UIImage(named: "flag")
let blockAction = SwipeAction(style: .destructive, title: "Block") { action, indexPath in
// handle action
}
deleteAction.image = UIImage(named: "block")
return [deleteAction, flagAction, blockAction]
}
}
我甚至尝试过以下内容:
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
// THIS GIVES THE DEFAULT 'DELETE' ACTION
print("Commit editingStyle")
}
func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [UITableViewRowAction]? {
print("editActionsForRowAtIndexPath")
let blockAction = UITableViewRowAction(style: UITableViewRowActionStyle.normal, title: "Block", handler: { (action:UITableViewRowAction, IndexPath:IndexPath) in
//self.isEditing = false
print("Block action Pressed")
})
let flagAction = UITableViewRowAction(style: UITableViewRowActionStyle.normal, title: "Flag", handler: { (action:UITableViewRowAction, IndexPath:IndexPath) in
print("Flag action Pressed")
})
let deleteAction = UITableViewRowAction(style: UITableViewRowActionStyle.destructive, title: "Delete", handler: { (action:UITableViewRowAction, IndexPath:IndexPath) in
print("Delete action Pressed")
})
return [blockAction, flagAction, deleteAction]
}
无论我做什么,我都不能仅仅通过滑动操作显示通用的“删除”操作。
我甚至不认为正在调用/引用以下函数:
func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [UITableViewRowAction]? {
我做错了什么,或者我需要CUD才能获得3次滑动操作;删除,标记和阻止,以使Apple对我的下一次提交感到满意。
提前谢谢大家!
答案 0 :(得分:0)
这个问题已经过时,但我会写下我认为可以解决的答案:)
你应该使用UITableViewController而不是UIViewController作为你的视图。 SwipeCellKit仅适用于TableViewControllers。
