阅读更多关于 Set custom font for UITableView swipe action (UIContextualAction)

问题 How do you set a custom font for the title in UIContextualAction ? I have tried UIAppearance but without any luck... Cheers! :) 回答1: I have found a way to do this by using the image property instead of the title...

UITableView: swiping RowAction cancels the selected rows

阅读更多关于 UITableView: swiping RowAction cancels the selected rows

问题 I can see this behavior in both deprecated UITableViewRowAction class and UISwipeActionsConfiguration class: If you have allowsMultipleSelection property set to true and, let's say, you have 3 rows selected: When you start swiping any row in the table for a RowAction the previously selected rows -- all 3 of them -- become unhighlighted, and the property indexPathsForSelectedRows drops to nil. Does this behavior make sense? Is there any 'deselecting' callback (because I'm displaying the number

tableView:editActionsForRowAt: on right-swipe?

阅读更多关于 tableView:editActionsForRowAt: on right-swipe?

问题 As I was using tableView:editActionsForRowAt: to provide some useful functionalities in an iOS app. func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? { print(#function) .... useful code ..... } I got to the point where some other API similar to the one above, but fired on a right swipe, rather than left swipe like tableView:editActionsForRowAt: would have been useful. Say something like: func tableView(_ tableView: UITableView,

Add strikethrough to tableview row with a swipe

阅读更多关于 Add strikethrough to tableview row with a swipe

问题 I've got a problem to strikethrough over the row text while swiping (E.G. left). I'm using the tableview method leadingSwipeActionsConfigurationForRowAt , but I can't find the solution to strikethrough text while swiping. As of now, the "swiped" row actually gets deleted. What I'm looking to do: Code: override func tableView(_ tableView: UITableView, leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? { let complete = completeAction(at: indexPath)

Why is the leading swipe action also duplicated as a trailing action?

阅读更多关于 Why is the leading swipe action also duplicated as a trailing action?

问题 I have implemented a leading swipe action ('Delete') on my tableView which for a reason I can't figure out is also appearing as a trailing swipe action. See code below: func tableView(_ tableView: UITableView, leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? { let delete1 = deleteAction(at: indexPath) return UISwipeActionsConfiguration(actions: [delete1]) } func deleteAction(at indexPath: IndexPath) -> UIContextualAction { let action =

Trailing swipe actions not dismissing

阅读更多关于 Trailing swipe actions not dismissing

问题 I have trailing swipe actions configured in my UITableView. The actions work correctly, but when an action removes the cell from the table, the swipe actions remain over the row that replaces the removed row. So it looks like the new current row is swiped. And I think the swipe actions may actually transfer their attachment to that new row, I can't tell. Is there some dismiss function I don't realize I need to call? 回答1: For your contextual action, don't forget to set your completion handler

Image in TableViewCell swipe action

I have a swipe action to 'complete' a task in my to-do list app. This is the image I have set: However when the cell is swiped, the image looks like this: Is there a way to make the background transparent/white and the image to have the green circle like the image above? If there is not, is there a way to make the green background 'wrap' to the purple of the cell so there is no whitespace? Thanks! In the second image, the green is the UIContextualAction's backgroundColor and the white is the tintColor . The image is treated as a template image — that is, its colors are ignored, and instead it
