Using Swift Locking with an Objective-C Wireframe

Question

I am using the MCSwipeTableViewCell environment for use in pageview tables. One of the completion blocks inside the function is cellForRowAtIndexPathas follows:

[cell setSwipeGestureWithView:checkView color:greenColor mode:MCSwipeTableViewCellModeSwitch state:MCSwipeTableViewCellState1 completionBlock:^(MCSwipeTableViewCell *cell, MCSwipeTableViewCellState state, MCSwipeTableViewCellMode mode) {
      // run some function call
}];

I used the Bridging-Header file to import the framework into my Swift project and am trying to use the same completion block in Swift. This is what I have:

cell.setSwipeGestureWithView(crossView, color: UIColor.colorFromRGB(RED), mode: MCSwipeTableViewCellMode.Switch, state:MCSwipeTableViewCellState.State1, completionBlock: { (cell: MCSwipeTableViewCell!, state: MCSwipeTableViewCellState!, mode: MCSwipeTableViewCellMode!) -> Void in
    self.runSomeFunction();
});

The problem is that it fires every time I run self.runSomeFunction(), even though the function call is implemented. Error

unrecognized selector

sent to instance 0x165c7390
2014-07-07 16:23:14.809 pong[3950:60b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayM runSomeFunction]: unrecognized selector sent to instance 0x165c7390'

I know that the completion block works because I can use NSLog and it displays something, but trying to access myself always fails.

Any ideas? Should I not try to access myself?

=== Update ===

, self Swift. .

,

 func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell!
{
    var cell = tableView.dequeueReusableCellWithIdentifier("userCell") as MCSwipeTableViewCell!

    if !cell {
        cell = MCSwipeTableViewCell(style: UITableViewCellStyle.Value1, reuseIdentifier: "userCell")
     }
    cell.setSwipeGestureWithView(crossView, color: UIColor.colorFromRGB(RED), mode: MCSwipeTableViewCellMode.Switch, state:MCSwipeTableViewCellState.State1, completionBlock: { (cell: MCSwipeTableViewCell!, state: MCSwipeTableViewCellState!, mode: MCSwipeTableViewCellMode!) -> Void in
        self.runSomething();
    });
    return cell
}

 func runSomething()
{
    NSLog("hey there");
}

Answer 1

Capture List, self Closure :

cell.setSwipeGestureWithView(crossView, color: UIColor.colorFromRGB(RED), mode: MCSwipeTableViewCellMode.Switch, state:MCSwipeTableViewCellState.State1) {
    [unowned self]
    cell, state, mode in
    self.runSomething()
}

[unowned self] , [weak self] self, : self!.doSomething().

Answer 2

self : [weak self]. , self nil:

if let weakSelf = self {
   // do whatever you want with the self
}
