Swift protocol prototypes

[dhoerl]

If anyone is interested:

func swipeTableCell(cell: MGSwipeTableCell!, canSwipe direction: MGSwipeDirection) -> Bool {
}

func swipeTableCell(cell: MGSwipeTableCell!, didChangeSwipeState state: MGSwipeState, gestureIsActive: Bool) {
}

func swipeTableCell(cell: MGSwipeTableCell!, tappedButtonAtIndex index: Int, direction: MGSwipeDirection, fromExpansion: Bool) -> Bool {
}

I'll add a demo using Swift soon, so I close this 'issue'.

May I ask you where is that Swift demo? I would really appreciate it!

Really, with the delegate prototypes I posted, you can get this framework supported in Swift easily.

I can't seem to implement the delegate methods in swift. They never seem to get called. Can you please post the demo / example?

here's a working example: (Swift 2.0, Xcode 7 beta 5)

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! MGSwipeTableCell        
    var recipe:Recipe = myRecipes[indexPath.row]

.
.
.
cell.delegate = self
let delButton = MGSwipeButton(title: "", icon:UIImage(named:"trashcan",inBundle:NSBundle.mainBundle(),compatibleWithTraitCollection:nil), backgroundColor: UIColor.redColor())

return cell

}

// MARK: - MGSwipeTableCellDelegate

func swipeTableCell(cell: MGSwipeTableCell!, canSwipe direction: MGSwipeDirection) -> Bool {
    return true
}

func swipeTableCell(cell: MGSwipeTableCell!, didChangeSwipeState state: MGSwipeState, gestureIsActive: Bool) {
}

func swipeTableCell(cell: MGSwipeTableCell!, tappedButtonAtIndex index: Int, direction: MGSwipeDirection, fromExpansion: Bool) -> Bool {
let indexPath = tableView.indexPathForCell(cell)
var recipe:Recipe = myRecipes[indexPath!.row]
let recipeToRemove = recipe as Recipe
self.myRecipes.removeAtIndex(indexPath!.row)
let managedContext = self.appDelegate.managedObjectContext
managedContext.deleteObject(recipeToRemove)
do {
try managedContext.save()
} catch {
let nserror = error as NSError
NSLog("Unresolved error (nserror), (nserror.userInfo)")
abort()
}
tableView.deleteRowsAtIndexPaths([indexPath!], withRowAnimation: UITableViewRowAnimation.Fade)
return true
}

@mhauss If your delegate methods are not being called you most likely are not setting the delegate for the cell:

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! MGSwipeTableCell
        cell.delegate = self
        ...
        return cell
    }

Where do I put these swift delegate method ?
