IOS native UIButton Click events are not allowed with multiple parameters, the only one parameter is the default UIButton itself so how do we implement a click event that passes multiple parameters?

2. UIButton *btn = //Create the button
4. Objc_setassociatedobject (BTN, "Firstobject", Someobject, objc_association_retain_nonatomic); //actually is KVC
6. Objc_setassociatedobject (BTN, "Secondobject", Otherobject, objc_association_retain_nonatomic);
10. [Btn addTarget:self Action:@selector (click:) forcontrolevents:uicontroleventtouchupinside];
14. -(void) Click: (UIButton *) Sender
16. {
18. ID first = Objc_getassociatedobject (BTN, "Firstobject"); //Take reference
20. ID second = Objc_setassociatedobject (btn, "Secondobject");
22. //etc.
24. }
