方法（1）

//左滑事件

- (nullable UISwipeActionsConfiguration *)tableView:(UITableView *)tableView trailingSwipeActionsConfigurationForRowAtIndexPath:(NSIndexPath *)indexPath API_AVAILABLE(ios(11.0)){

    return [UISwipeActionsConfiguration configurationWithActions:[self getActionsWithType:indexPath]];

}

-(NSArray*)getActionsWithType:(NSIndexPath*)indexPath{

    RYMFriendModel *model = [[self.letterResultArr objectAtIndex:indexPath.section] objectAtIndex:indexPath.row];

    NSArray*titleArrray;

    titleArrray = @[@"删除",@"编辑"];

    SXWeakSelf

    UIContextualAction *action1 = [UIContextualAction contextualActionWithStyle:UIContextualActionStyleDestructive title:titleArrray[0] handler:^(UIContextualAction * _Nonnull action, __kindof UIView * _Nonnull sourceView, void (^ _Nonnull completionHandler)(BOOL)) {

         NSLog(@"UIContextualAction-删除要实现的代码");

        completionHandler(NO);//调用次回调以后,点击以后会回到复原Cell,传YES/NO没有发现区别

    }];

    UIContextualAction *action2 = [UIContextualAction contextualActionWithStyle:UIContextualActionStyleNormal title:titleArrray[1] handler:^(UIContextualAction * _Nonnull action, __kindof UIView * _Nonnull sourceView, void (^ _Nonnull completionHandler)(BOOL)) {

        completionHandler(NO);

    }];

    action1.backgroundColor= [UIColorcolorWithRed:227/255.0green:90/255.0blue:80/255.0alpha:1];

    action2.backgroundColor= [UIColorcolorWithRed:227/255.0green:151/255.0blue:73/255.0alpha:1];

    return@[action1,action2];

}

方法（2）

// 允许进入编辑状态

- (BOOL)tableView:(UITableView*)tableViewcanEditRowAtIndexPath:(NSIndexPath*)indexPath{

    return Yes;

}

// 自定义cell的编辑模式

- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath {

    return UITableViewCellEditingStyleDelete;

}

// 进入编辑模式，确定编辑提交操作时，执行的代理方法

- (void)tableView:(UITableView*)tableViewcommitEditingStyle:(UITableViewCellEditingStyle)editingStyleforRowAtIndexPath:(NSIndexPath*)indexPath{

}

方法（3）

- (NSArray*)tableView:(UITableView*)tableVieweditActionsForRowAtIndexPath:(NSIndexPath*)indexPath {

    //删除

    SXWeakSelf;

    UITableViewRowAction *deleteRowAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDestructive title:@"删除" handler:^(UITableViewRowAction * _Nonnull action, NSIndexPath * _Nonnull indexPath) {

        [weakSelfdealDeteleWith:indexPath];

    }];

    //编辑

//    UITableViewRowAction *editRowAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleNormal title:@"编辑" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {

//

//    }];

//    return @[deleteRowAction,editRowAction];

    return@[deleteRowAction];
