How can I get UIButton to execute a class method while listening?

Question

How can I make UIButton execute my method of class +doSomething:(id)sender in class MyClass after any event, for example UIControlEventTouchDown ? Is it possible to use -addTarget:action:forControlEvents: like I, for example, methods?

Thanks in advance.

Answer 1

Since classes are also ObjC objects, you can use -addTarget:... , as usual:

 [button addTarget:[MyClass class] action:@selector(classMethod:) forControlEvents:UIControlEventTouchUpInside]; 

Answer 2

Add an intermediate method that will call the class method.

 [button addTarget:self action:@selector(callClassMethod:) forControlEvents: UIControlEventTouchDown]; - (void)callClassMethod:(id)sender { [MyClass classMethod:sender]; }
