SKAction launch method with argument?

I am trying to run SKAction *action = [SKAction performSelector:(SEL) onTarget:(id)];

and pass in a selector, which is a method that takes one argument. However, Xcode will allow me to insert performSelector:@selector(placeCoin:)

, but it will not allow me to pass the CGPoint argument to the selector. How am I supposed to do this? Should I seriously run it with the SKAction runBlock statement? It looks like there must be a way to do this.

As far as I know, you cannot pass any arguments using performSelector:onTarget:

in SpriteKit. Using blocks is the best way to go.

This question is a little outdated, but I found an easy way to do it.

First create your action (in my case, I need an action that repeats forever):

-(void)MyAction
{
   SKAction *wait = [SKAction waitForDuration: 0.01];
   SKAction *performSelector = [SKAction performSelector:@selector(myMethod1) onTarget:self];
   SKAction *sequence = [SKAction sequence:@[performSelector, wait]];
   SKAction *repeat = [SKAction repeatActionForever: sequence];
}


Then create myMethod1 and run the required method with arguments:

-(void)myMethod1
{
  [self myMethod2Arg1:something1 Arg2:something2 Arg3:something3];
}

Now all you have to do is launch an action on anything, and the method with arguments will be launched.
