I'm making a little banking type app, for instructional purposes.
All transactions are stored as Core Data entities, fetched and sorted using Magical Record helper methods. The transactions are displayed in a UITableView
, fed by a fetchedObjects
array.
I want to be able to use editActionsForRowAtIndexPath
like so:
The first action segues to another uiviewController
, the second and third to a UIPopoverPresentationController
. The fourth button deletes the transaction.
EDIT
Here's the code to create the buttons:
- (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 *)myArray:(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
}
Here's my question:
How do I tell which button to trigger which segue? I can't figure how to make the connections.
Here's a representative chunk of code from my prepareForSegue
. One point of my confusion is indicated by the ??? in the argument for the sourceRect
:
else if ([[segue identifier] isEqualToString:@"AmountPopSegue"])
{
UIViewController *controller = segue.destinationViewController;
controller.popoverPresentationController.delegate = self;
controller.preferredContentSize = CGSizeMake(320, 186);
UIPopoverPresentationController *thisPPC = controller.popoverPresentationController;
thisNavController = (UINavigationController *)segue.destinationViewController;
AmountChangePopVC *acVC = (AmountChangePopVC *)thisNavController.topViewController;
acVC.delegate = self;
thisPPC.sourceRect = ???;
}
All insights appreciated. I'm writing in Objective C because I started this project before Swift became all the rage.
