Disappearing editActionsForRowAtIndexPath actions - ios

Question

I want to implement editActionsForRowAtIndexPath to display several options when I left-swipe a cell in my UITableview. So I used this code:
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
//Obviously, if this returns no, the edit option won't even populate
return YES;
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
//Nothing gets called here if you invoke `tableView:editActionsForRowAtIndexPath:` according to Apple docs so just leave this method blank
}
-(NSArray *)tableview:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewRowAction *delete = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Delete" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// Delete code here
}];
UITableViewRowAction *changeAmt = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Amt" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// popover amount change code
}];
changeAmt.backgroundColor = [UIColor colorWithRed:0.022 green:0.541 blue:0.001 alpha:1.00];
UITableViewRowAction *changeAcct = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Acct" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// popover account change code
}];
changeAcct.backgroundColor = [UIColor colorWithRed:1.000 green:0.492 blue:0.000 alpha:1.00];
UITableViewRowAction *viewTrans = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"View" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// Push to view
}];
viewTrans.backgroundColor = [UIColor colorWithRed:0.002 green:0.342 blue:0.710 alpha:1.00];
return #[delete,changeAmt,changeAcct,viewTrans]; //array with the buttons delete, changeAmt, changeAcct, viewTrans
}
Yesterday, this code produced this result:
Today, I decided to eliminate the viewTrans action by modifying the editActionsForRowAtIndexPath method like this:
-(NSArray *)tableview:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewRowAction *delete = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Delete" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// Delete code here
}];
UITableViewRowAction *changeAmt = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Amt" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// popover amount change code
}];
changeAmt.backgroundColor = [UIColor colorWithRed:0.022 green:0.541 blue:0.001 alpha:1.00];
UITableViewRowAction *changeAcct = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Acct" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// popover account change code
}];
changeAcct.backgroundColor = [UIColor colorWithRed:1.000 green:0.492 blue:0.000 alpha:1.00];
// UITableViewRowAction *viewTrans = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"View" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
// {
// // Push to view
// }];
// viewTrans.backgroundColor = [UIColor colorWithRed:0.002 green:0.342 blue:0.710 alpha:1.00];
return #[delete,changeAmt,changeAcct]; //array with the buttons delete, changeAmt, changeAcct, viewTrans
}
This modified code had the effect, somehow, of removing all the actions except the default Delete action:
So I uncommented the code, and replaced the reference to the viewTrans action in the return line. The extra actions do not reappear.
This is the only code I modified. Anybody have any idea what I did wrong?

Answer 1

I had been working on your question and initially, I can't get editActionsForRowAtIndexPath method called but later I found a little problem and maybe is the same for you, the declaration for the method
-(NSArray *)tableview:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
is not right, the correct is
- (nullable NSArray<UITableViewRowAction *> *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
so my method stay like this
- (nullable NSArray<UITableViewRowAction *> *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewRowAction *delete = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Delete" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// Delete code here
}];
UITableViewRowAction *changeAmt = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Amt" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// popover amount change code
}];
changeAmt.backgroundColor = [UIColor colorWithRed:0.022 green:0.541 blue:0.001 alpha:1.00];
UITableViewRowAction *changeAcct = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Acct" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// popover account change code
}];
changeAcct.backgroundColor = [UIColor colorWithRed:1.000 green:0.492 blue:0.000 alpha:1.00];
//UITableViewRowAction *viewTrans = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"View" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
// {
// Push to view
// }];
//viewTrans.backgroundColor = [UIColor colorWithRed:0.002 green:0.342 blue:0.710 alpha:1.00];
return #[delete,changeAmt,changeAcct]; //array with the buttons delete, changeAmt, changeAcct, viewTrans
}
And this is how it looks
I hope this helps you
