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,我在我的trailingActions方法中返回nil,我仍然可以在我的tableview中完全滑动删除。如何防止完全滑动? (我希望用户必须滑动然后按“删除”按钮。
@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。即使在我实现了trailingSwipeActionsConfigurationForRowAt之前,也启用了完全滑动。

实施如下:
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
如果您实施editingStyle
和editActionsForRowAt
之类的其他功能,请删除其他功能。

我可以按照以下答案为特定单元格禁用滑动操作: https://stackoverflow.com/a/50597672/1072262
您可以返回以下内容,而不是返回nil:
return UISwipeActionsConfiguration.init()
