I have the following code:\r\n\r\n```objc\r\n[self rz_addTarget:self action:@selector(senderDidChange:) forKeyPathChange:RZDB_KP_SELF(sender)];\r\n```\r\n\r\nIt compiles, but when it tries to run it throws an error of unrecognised selector being sent to the instance. The `self`object is a direct subclass of NSObject.\r\n\r\nAny idea what is going wrong here?"}}
