如何禁用iOS11中tableview单元格的完全滑动 [英] How do I disable the full swipe on a tableview cell in iOS11

问题描述

UITableViewDelegate.h

UITableViewDelegate.h

// Swipe actions
// These methods supersede -editActionsForRowAtIndexPath: if implemented
// return nil to get the default swipe actions
- (nullable UISwipeActionsConfiguration *)tableView:(UITableView *)tableView leadingSwipeActionsConfigurationForRowAtIndexPath:(NSIndexPath *)indexPath API_AVAILABLE(ios(11.0)) API_UNAVAILABLE(tvos);
- (nullable UISwipeActionsConfiguration *)tableView:(UITableView *)tableView trailingSwipeActionsConfigurationForRowAtIndexPath:(NSIndexPath *)indexPath API_AVAILABLE(ios(11.0)) API_UNAVAILABLE(tvos);

但是，我在trailingActions方法中返回nil，我仍然可以完全滑动删除我的桌面视图。如何防止完全滑动？ （我希望用户必须滑动然后按删除按钮。

However, I am returning nil in my trailingActions method and I still can do a full swipe to delete in my tableview. How can I prevent the full swipe? (I want the user to have to swipe then press the "Delete" button.

@available(iOS 11.0, *)
func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
    return nil
}

编辑：在iOS 11 / XCode 9 / Swift 4更新之前，我已经实现了canEditRowAt并提交了编辑样式。甚至在我实现trailingSwipeActionsConfigurationForRowAt之前，已经启用了完全滑动。

I had implemented canEditRowAt and commit Editing style before the iOS 11/XCode 9/Swift 4 update. The full swipe was enabled even BEFORE I implemented the trailingSwipeActionsConfigurationForRowAt.

推荐答案

如下所示：

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
    let delete = UIContextualAction(style: .destructive, title: "Delete") { (action, sourceView, completionHandler) in
        print("index path of delete: \(indexPath)")
        completionHandler(true)
    }
    let swipeAction = UISwipeActionsConfiguration(actions: [delete])
    swipeAction.performsFirstActionWithFullSwipe = false // This is the line which disables full swipe
    return swipeAction
}

这是禁用完全滑动的行

swipeAction.performsFirstActionWithFullSwipe = false 

如果实施，请删除其他功能任何像 editingStyle 和 editActionsForRowAt 。

And remove the other functions if you implement any like editingStyle and editActionsForRowAt.
