Change Swipe Button Title After Completion - swift

Question

I have the following code:
cell.rightButtons = [MGSwipeButton(title: "Save", backgroundColor:UIColor.redColor(),callback: {
(sender: MGSwipeTableCell!) -> Bool in
print("Saved")
return true
}))]
cell.rightSwipeSettings.transition = MGSwipeTransition.Rotate3D
return cell
This works fine but I want to change the title from "Save" to remove afterward. Tried it many different ways but doesn't seem to be working.

As explained in the official project: MGSwipeTableCell
you can obtain the button pressed by calling the delegate method:
-(BOOL) swipeTableCell:(MGSwipeTableCell*) cell tappedButtonAtIndex:(NSInteger) index direction:(MGSwipeDirection)direction fromExpansion:(BOOL) fromExpansion;
/**
* Delegate method to setup the swipe buttons and swipe/expansion settings
* Buttons can be any kind of UIView but it's recommended to use the convenience MGSwipeButton class
* Setting up buttons with this delegate instead of using cell properties improves memory usage because buttons are only created in demand
* #param swipeTableCell the UITableVieCel to configure. You can get the indexPath using [tableView indexPathForCell:cell]
* #param direction The swipe direction (left to right or right to left)
* #param swipeSettings instance to configure the swipe transition and setting (optional)
* #param expansionSettings instance to configure button expansions (optional)
* #return Buttons array
**/
In Swift you can write:
func swipeTableCell(cell: MGSwipeTableCell!, tappedButtonAtIndex index: Int, direction: MGSwipeDirection, fromExpansion: Bool) -> Bool {
if let button = cell.rightbuttons[index] {
print(button.titleLabel.text)
button.setTitle("Button Title", forState: UIControlState.Normal)
... (do whatever you want with your tapped button..)
}
}
To help you can launch the MGSwipeDemo project included in the bundle source, and add these lines in objective c like in this screenshots:
-(BOOL) swipeTableCell:(MGSwipeTableCell*) cell tappedButtonAtIndex:(NSInteger) index direction:(MGSwipeDirection)direction fromExpansion:(BOOL) fromExpansion
{
...
if (direction == MGSwipeDirectionRightToLeft && index == 1) {
NSLog(#"more pressed");
id button = cell.rightButtons[index];
UIButton *pressedBtn = button;
[pressedBtn setTitle:#"Less" forState:UIControlStateNormal];
NSLog(#"pressedBtn title: %#",pressedBtn.titleLabel.text);
}
...
}
P.S.: update: this part was added to help during comments:
About your personal project you must add to your datasource any boolean var, i make an example (in Swift code):
Class rowData{
var title: String! = String()
var subTitle:String! = String()
var button1Title : String! = String()
var button2Title : String! = String()
var isSaved : Bool! = false
}
var myDataSource : [rowData]! = [rowData]()
So, when you had populate your datasource you can use the delegate:
func swipeTableCell(cell: MGSwipeTableCell!, tappedButtonAtIndex index: Int, direction: MGSwipeDirection, fromExpansion: Bool) -> Bool {
...
if (direction == MGSwipeDirection.RightToLeft && index == 2){
if let _= cell?.rightButtons[index]{
let cellData:rowData = myDataSource[index]
if cellData.isSaved {
cellData.buttonTitle1 = "Just saved"
cellData.isSaved = true
} else {
cellData.buttonTitle1 = "Save"
cellData.isSaved = false
}
myDataSource[index] = cellData
// datasource is modified so launch reload data to refresh layout and call cellForRow..
// There are other softly methods than reloadData to update tableView layout but I use it just for example..
self.tableView.reloadData()
}
}
...
}
