我使用tableViewCell来显示多个数据，在一个单元格上从右向左滑动()后，它将显示两个按钮批准和拒绝，有两个方法，第一个是ApproveFunc，它需要一个参数，另一个是RejectFunc，它也需要一个参数。

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
        let Approve = UITableViewRowAction(style: .normal, title: "Approve") { action, index in

            self.ApproveFunc(indexPath: indexPath)
        }
        Approve.backgroundColor = .green

        let Reject = UITableViewRowAction(style: .normal, title: "Reject") { action, index in

            self.rejectFunc(indexPath: indexPath)
        }
        Reject.backgroundColor = .red



        return [Reject, Approve]
    }

    func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
        return true
    }

    func ApproveFunc(indexPath: IndexPath) {
        print(indexPath.row)
    }
    func rejectFunc(indexPath: IndexPath) {
        print(indexPath.row)
    }

我创建了一个新的库来实现可滑动的按钮，它支持各种过渡和可扩展的按钮，如iOS 8邮件应用程序。

https://github.com/MortimerGoro/MGSwipeTableCell

这个库兼容所有创建UITableViewCell的不同方法，它在iOS 5、iOS 6、iOS 7和iOS 8上进行了测试。

以下是一些过渡的例子:

边境的转变:

夹过渡

3 d的转变:

这里有一个简单的解决办法。它能够在UITableViewCell中显示和隐藏自定义UIView。 显示逻辑包含在从UITableViewCell, BaseTableViewCell扩展的类中。

BaseTableViewCell.h

#import <UIKit/UIKit.h>

@interface BaseTableViewCell : UITableViewCell

@property(nonatomic,strong)UIView* customView;

-(void)showCustomView;

-(void)hideCustomView;

@end

BaseTableViewCell。米

#import "BaseTableViewCell.h"

@interface BaseTableViewCell()
{
    BOOL _isCustomViewVisible;
}

@end

@implementation BaseTableViewCell

- (void)awakeFromNib {
    // Initialization code
}

-(void)prepareForReuse
{
    self.customView = nil;
    _isCustomViewVisible = NO;
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
    [super setSelected:selected animated:animated];

    // Configure the view for the selected state
}

-(void)showCustomView
{
    if(nil != self.customView)
    {
        if(!_isCustomViewVisible)
        {
            _isCustomViewVisible = YES;

            if(!self.customView.superview)
            {
                CGRect frame = self.customView.frame;
                frame.origin.x = self.contentView.frame.size.width;
                self.customView.frame = frame;
                [self.customView willMoveToSuperview:self.contentView];
                [self.contentView addSubview:self.customView];
                [self.customView didMoveToSuperview];
            }

            __weak BaseTableViewCell* blockSelf = self;
            [UIView animateWithDuration:.5 animations:^(){

                for(UIView* view in blockSelf.contentView.subviews)
                {
                    CGRect frame = view.frame;
                    frame.origin.x = frame.origin.x - blockSelf.customView.frame.size.width;
                    view.frame = frame;
                }
            }];
        }
    }
}

-(void)hideCustomView
{
    if(nil != self.customView)
    {
        if(_isCustomViewVisible)
        {
            __weak BaseTableViewCell* blockSelf = self;
            _isCustomViewVisible = NO;
            [UIView animateWithDuration:.5 animations:^(){
                for(UIView* view in blockSelf.contentView.subviews)
                {
                    CGRect frame = view.frame;
                    frame.origin.x = frame.origin.x + blockSelf.customView.frame.size.width;
                    view.frame = frame;
                }
            }];
        }
    }
}

@end

要获得此功能，只需从BaseTableViewCell扩展您的表视图单元格。

接下来, 在UIViewController中，它实现了UITableViewDelegate，创建了两个手势识别器来处理左右滑动。

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    [self.tableView registerNib:[UINib nibWithNibName:CUSTOM_CELL_NIB_NAME bundle:nil] forCellReuseIdentifier:CUSTOM_CELL_ID];

    UISwipeGestureRecognizer* leftSwipeRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleLeftSwipe:)];
    leftSwipeRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
    [self.tableView addGestureRecognizer:leftSwipeRecognizer];

    UISwipeGestureRecognizer* rightSwipeRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleRightSwipe:)];
    rightSwipeRecognizer.direction = UISwipeGestureRecognizerDirectionRight;
    [self.tableView addGestureRecognizer:rightSwipeRecognizer];
}

然后添加两个滑动处理程序

- (void)handleLeftSwipe:(UISwipeGestureRecognizer*)recognizer
{
    CGPoint point = [recognizer locationInView:self.tableView];
    NSIndexPath* index = [self.tableView indexPathForRowAtPoint:point];

    UITableViewCell* cell = [self.tableView cellForRowAtIndexPath:index];

    if([cell respondsToSelector:@selector(showCustomView)])
    {
        [cell performSelector:@selector(showCustomView)];
    }
}

- (void)handleRightSwipe:(UISwipeGestureRecognizer*)recognizer
{
    CGPoint point = [recognizer locationInView:self.tableView];
    NSIndexPath* index = [self.tableView indexPathForRowAtPoint:point];

    UITableViewCell* cell = [self.tableView cellForRowAtIndexPath:index];

    if([cell respondsToSelector:@selector(hideCustomView)])
    {
        [cell performSelector:@selector(hideCustomView)];
    }
}

现在，在UITableViewDelegate的cellForRowAtIndexPath中，你可以创建自定义UIView并将它附加到dequeuedcell中。

-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    CustomCellTableViewCell* cell = (CustomCellTableViewCell*)[tableView dequeueReusableCellWithIdentifier:@"CustomCellTableViewCell" forIndexPath:indexPath];

    NSArray* nibViews = [[NSBundle mainBundle] loadNibNamed:@"CellCustomView"
                                                      owner:nil
                                                    options:nil];

    CellCustomView* customView = (CellCustomView*)[ nibViews objectAtIndex: 0];

    cell.customView = customView;

    return cell;
}

当然，这种加载自定义UIView的方式只适用于这个例子。按照您的意愿管理它。

用于快速编程

func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
  if editingStyle == UITableViewCellEditingStyle.Delete {
    deleteModelAt(indexPath.row)
    self.tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Automatic)
  }
  else if editingStyle == UITableViewCellEditingStyle.Insert {
    println("insert editing action")
  }
}

func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject]? {
  var archiveAction = UITableViewRowAction(style: .Default, title: "Archive",handler: { (action: UITableViewRowAction!, indexPath: NSIndexPath!) in
        // maybe show an action sheet with more options
        self.tableView.setEditing(false, animated: false)
      }
  )
  archiveAction.backgroundColor = UIColor.lightGrayColor()

  var deleteAction = UITableViewRowAction(style: .Normal, title: "Delete",
      handler: { (action: UITableViewRowAction!, indexPath: NSIndexPath!) in
        self.deleteModelAt(indexPath.row)
        self.tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Automatic);
      }
  );
  deleteAction.backgroundColor = UIColor.redColor()

  return [deleteAction, archiveAction]
}

func deleteModelAt(index: Int) {
  //... delete logic for model
}

你需要子类化UITableViewCell和子类化方法willTransitionToState:(UITableViewCellStateMask)状态，该状态在用户滑动单元格时被调用。状态标志会让你知道是否显示删除按钮，并在那里显示/隐藏更多按钮。

不幸的是，这个方法既没有给你Delete按钮的宽度，也没有给你动画时间。所以你需要观察并将More按钮的帧和动画时间硬编码到你的代码中(我个人认为苹果需要在这方面做些什么)。

在iOS 11中，这在UITableViewDelegate中是公开的。下面是一些示例代码:

斯威夫特

func tableView(_ tableView: UITableView, leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {

    let action = UIContextualAction(style: .normal, title: nil) { (_, _, _) in
        print("Swipe action tapped")
    }

    action.image = UIImage(systemName: "plus.slash.minus")
    action.backgroundColor = .green

    return UISwipeActionsConfiguration(actions: [action])
}

Objective - C

- (UISwipeActionsConfiguration *)tableView:(UITableView *)tableView trailingSwipeActionsConfigurationForRowAtIndexPath:(NSIndexPath *)indexPath {
    UIContextualAction *delete = [UIContextualAction contextualActionWithStyle:UIContextualActionStyleDestructive
                                                                         title:@"DELETE"
                                                                       handler:^(UIContextualAction * _Nonnull action, __kindof UIView * _Nonnull sourceView, void (^ _Nonnull completionHandler)(BOOL)) {
                                                                           NSLog(@"index path of delete: %@", indexPath);
                                                                           completionHandler(YES);
                                                                       }];

    UIContextualAction *rename = [UIContextualAction contextualActionWithStyle:UIContextualActionStyleNormal
                                                                         title:@"RENAME"
                                                                       handler:^(UIContextualAction * _Nonnull action, __kindof UIView * _Nonnull sourceView, void (^ _Nonnull completionHandler)(BOOL)) {
                                                                           NSLog(@"index path of rename: %@", indexPath);
                                                                           completionHandler(YES);
                                                                       }];

    UISwipeActionsConfiguration *swipeActionConfig = [UISwipeActionsConfiguration configurationWithActions:@[rename, delete]];
    swipeActionConfig.performsFirstActionWithFullSwipe = NO;

    return swipeActionConfig;
}

也可用:

- (UISwipeActionsConfiguration *)tableView:(UITableView *)tableView leadingSwipeActionsConfigurationForRowAtIndexPath:(NSIndexPath *)indexPath;
