Replacing @selector with direct code

Question

Possible Duplicate:
Can I pass a block as a @selector with Objective-C?

I have this code:

[myButton addTarget:self action:@selector(doSomething:) forControlEvents:UIControlEventTouchUpInside];

But since doSomething contains so little code, I was wondering if it is possible to put the code straight in here rather than making it run doSomething.

I have tried this already:

[myButton addTarget:self action:^ { /* code here */ } forControlEvents:UIControlEventTouchUpInside];

But it just gives an error of "sending (void)^(void) to incompatible type SEL".

Is there a way to do this? If so what is the correct syntax?

Thanks!

How have you even considered that this would work at all? – Oct 17 '12 at 18:14 — , Oct 17 '12 at 18:14

Well, all of your answers use a lot of unnecessary code which is horribly outdated and no longer works.

I found one answer myself though which I adapted and got this:

[myButton addTarget:[^{NSLog(@"Pressed the button");} copy] action:@selector(invoke) forControlEvents:UIControlEventTouchUpInside];

Which works fine.
