Add/Delete UITableViewCell with animation?
I know this might sound like a dumb question, but I have looked every where. How can I do this?
I know how to do this with a swype-to-delete method, but how cam I do it outside that function?
Please post some code samples.
Thanks开发者_运维问答!
Coulton[self.tableView beginUpdates];
[self.tableView insertRowsAtIndexPaths:insertIndexPaths withRowAnimation:UITableViewRowAnimationFade];
[self.tableView deleteRowsAtIndexPaths:deleteIndexPaths withRowAnimation:UITableViewRowAnimationFade];
[self.tableView endUpdates];
insertIndexPaths
is an array of NSIndexPaths to be inserted to your table.
deleteIndexPaths
is a array of NSIndexPaths to be deleted from your table.
Example array format for index paths :
NSArray *insertIndexPaths = [[NSArray alloc] initWithObjects:
[NSIndexPath indexPathForRow:0 inSection:0],
[NSIndexPath indexPathForRow:1 inSection:0],
[NSIndexPath indexPathForRow:2 inSection:0],
nil];
In Swift 2.1+
tableView.beginUpdates()
tableView.deleteRowsAtIndexPaths([YourIndexPathYouWantToDeleteFrom], withRowAnimation: .Fade)
tableView.insertRowsAtIndexPaths([YourIndexPathYouWantToInsertTo], withRowAnimation: .Fade)
tableView.endUpdates()
And you can create an NSIndexPath easily like so:
NSIndexPath(forRow: 0, inSection: 0)
You want these two methods: insertRowsAtIndexPaths:withRowAnimation:
and deleteSections:withRowAnimation:
They are both detailed in the UITableView documentation.
Swift 4.0
tableView.beginUpdates()
tableView.deleteRows(at: [YourIndexPathYouWantToDeleteFrom], with: .fade)
tableView.insertRows(at: [YourIndexPathYouWantToInsertTo], with: .fade)
tableView.endUpdates()
For creating IndexPath use this:
IndexPath(row: 0, section: 0)
