Can anyone help me understand this objective-c code?

UISwitch *whichSwitch = (UISwitch *) sender;
BOOL setting = whichSwitch.isOn;
[leftswitch setOn:setting animated:YES];
[rightswitch SetOn:setting animating:YES];

The last two lines especially leave me clueless.

 

It looks like whatever class leftswitch and rightswitch belong to has a method called setOn:animating: that takes two BOOL values. In this case it's passing the value of setting, which will be YES or NO for setOn, and YES for animating.

Thanks Lee!

I get it now.

 

Objective C is case sensitive so setOn and SetOn are different. In this code it looks like its probably a typo, but watch out for this.
