如何在swift IOS中实现左右滑动以更改数据/视图?
我想实现左右滑动手势功能,以更改swift 5中的数据视图。 我有两个ViewController-如何在swift IOS中实现左右滑动以更改数据/视图?,ios,swift,uitableview,swipe,Ios,Swift,Uitableview,Swipe,我想实现左右滑动手势功能,以更改swift 5中的数据视图。 我有两个ViewController-FeedsController,其中包含tableview和其中所有视频的列表。在FeedsController中,如果我单击comment按钮,它将移动到commentViewController,并显示带有详细注释的相同视频。 实际上,我想在commentViewController上实现滑动手势动作,这样用户甚至可以在细节评论页面(即commentViewController)上左右滑动 C
FeedsController
,其中包含tableview和其中所有视频的列表。在FeedsController
中,如果我单击comment按钮,它将移动到commentViewController
,并显示带有详细注释的相同视频。
实际上,我想在commentViewController
上实现滑动手势动作,这样用户甚至可以在细节评论页面(即commentViewController
)上左右滑动
CommentViewController的代码:
import UIKit
import FloatingPanel
final class CommentsViewController: UIViewController, CommentsViewInput, FloatingPanelControllerDelegate {
var post: IContentPost!
private var output: CommentsViewOutput?
private var fpc: FloatingPanelController!
private var mute: Bool {

}
private weak var contentVC: BottomSheetInputView?
private let router = Router()
@IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
setup()
swipeGesture()
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
fpc.removePanelFromParent(animated: true)
}
@IBAction func dismissAction(_ sender: Any) {
dismiss(animated: true, completion: nil)
}
func swipeGesture(){
let leftSwipe = UISwipeGestureRecognizer(target: self, action: #selector(handleSwipes(_:)))
let rightSwipe = UISwipeGestureRecognizer(target: self, action: #selector(handleSwipes(_:)))
leftSwipe.direction = .left
rightSwipe.direction = .right
view.addGestureRecognizer(leftSwipe)
view.addGestureRecognizer(rightSwipe)
}
@objc func handleSwipes(_ sender:UISwipeGestureRecognizer)
{
if (sender.direction == .left)
{
print("Swipe Left")

if (sender.direction == .right)
{
print("Swipe Right")
}
}
private func setup() {
let presenter = CommentsPresentationModel(view: self, post: post)
self.output = presenter
setupTableView()
setupPanel()
output?.getComments() { [weak self] comments in
guard let comments = comments else { return }
self?.contentVC?.updateComments(with: comments)

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

- Use 2 different functions to handle different swipe gestures
- Add following in
viewDidLoad()
up to Swift 4.0
var swipeRight = UISwipeGestureRecognizer(target: self, action: #selector(self.swipedRight))
swipeRight.direction = UISwipeGestureRecognizerDirection.right
var swipeLeft = UISwipeGestureRecognizer(target: self, action: #selector(self.swipedLeft))
swipeLeft.direction = UISwipeGestureRecognizerDirection.left
self.view.addGestureRecognizer(swipeLeft)
self.view.addGestureRecognizer(swipeRight)
导入UIKit
导入浮动面板
最后一个类CommentsViewController:UIViewController、CommentsViewInput、FloatingPanelControllerDelegate{
var post:IContentPost!
私有变量输出:CommentsViewOutput?
私有var fpc:FloatingPanelController!
私家车:布尔{
返回为VideoPlayerController.sharedVideoPlayer.mute
}
私有弱var内容VC:BottomSheetInputView?
私有let路由器=路由器()
@IBVAR表格视图:UITableView!
重写func viewDidLoad(){
super.viewDidLoad()
设置()
swipeGesture()
}
覆盖函数视图将消失(u动画:Bool){
超级。视图将消失(动画)
fpc.removePanelFromParent(动画:true)
}
@IBAction func dismissAction(\发送方:任意){
驳回(动画:真,完成:无)
}
func swipeGesture(){
让leftSwipe=UISwipegestureRecognitor(目标:self,操作:#选择器(handleSwipes(:))
让rightSwipe=UISwipegestureRecognitor(目标:self,操作:#选择器(handleSwipes(:))
leftSwipe.direction=.left
rightSwipe.direction=.right
view.AddGestureRecognitor(左扫)
view.AddGestureRecognitor(右击)
}
@objc func handleSwipes(\发送方:UISwipegestureRecognitor)
{
如果(发送方方向==.左)
{
打印(“向左滑动”)
}
if(sender.direction==.right)
{
打印(“向右滑动”)
}
}
专用函数设置(){
让演示者=评论演示模型(视图:self,post:post)
self.output=presenter
setupTableView()
设置面板()
输出?.getComments(){[weak self]中的注释
guard let comments=comments else{return}
self?.contentVC?.updateComments(带:注释)
}
}
专用功能设置面板(){
fpc=浮动面板控制器()
fpc.delegate=自//可选
让contentVC=router.bottomVC()
contentVC.delegate=self
self.contentVC=contentVC
fpc.set(contentViewController:contentVC)
fpc.track(滚动视图:contentVC.tableView)
fpc.addPanel(主客户:自身)
}
专用函数setupTableView(){
tableView.delegate=self
tableView.dataSource=self
tableView?.registerReusableCell(FeedContentTableViewCell.self)
}
}
扩展注释ViewController:UITableViewDelegate,UITableViewDataSource{
func tableView(tableView:UITableView,numberofrowsinssection:Int)->Int{
返回1
}
func tableView(tableView:UITableView,cellForRowAt indexath:indexPath)->UITableViewCell{
let cell:FeedContentTableViewCell=tableView.dequeueReusableCell(for:indexPath)
cell.delegate=self
单元格设置(带:post、静音:静音、需要插入:false)
返回单元
}
}
扩展注释viewcontroller:FeedContentCellDelegate{
func-likePressed(id:String){
输出?.postId(postId:id)
}
func CommentPost(发布:IContentPost){
fpc.show(动画:真,完成:无)
}
func sharePressed(id:字符串){
输出?.postShared(postId:id)
让text=“嘿!你得看看!
- 使用两种不同的功能处理不同的刷卡手势
- 在
viewDidLoad()中添加以下内容
最高达Swift 4.0
var swipeRight = UISwipeGestureRecognizer(target: self, action: #selector(self.swipedRight))
swipeRight.direction = UISwipeGestureRecognizer.Direction.right
var swipeLeft = UISwipeGestureRecognizer(target: self, action: #selector(self.swipedLeft))
swipeLeft.direction = UISwipeGestureRecognizer.Direction.left
self.view.addGestureRecognizer(swipeLeft)
self.view.addGestureRecognizer(swipeRight)
Swift 4.2及以后版本:
“UISweepGestureRecognitizerDirection”已重命名为“UISweepGestureRecognitizer.Direction”
- 创建两个objc函数
swipedRight
和swipedLeft
@objc func swipedRight()
{
//在此处添加您的记录更改代码
}
@objc func swipedLeft()
{
//在此处添加您的记录更改代码
}

是否要执行滑动删除或类似操作?@MojtabaHosseini no不删除。滑动更改记录。对于您的情况,请执行UIPageViewController向左和向右滑动以查看上一个/下一个视频评论。@Mani但您能指导我如何实现吗?正如我提到的,我有包含视频列表的tableviewd下面的评论按钮就像insta类型一样,点击后会进入评论-详细信息页面,上面和下面都有视频,但我想更改滑动内容,这样用户就不会在同一个CommentViewController中返回。用户可以使用滑动手势。您想实现滑动删除或类似操作吗?@MojtabaHosseini no不删除.滑动以更改记录。对于您的情况,请使用UIPageViewController向左和向右滑动以查看上一个/下一个视频评论。@Mani但您能指导我如何实现这一点吗?正如我所提到的
