Re: Checking a method for parameter types via SEL

What you are doing looks bizarre to me.
 
  How about
 
  @implementation NSCoder (ConditionalCoding)

-(void)encodeObject:(id)obj onCondition:(SEL)cond withOwner:(id)owner
{
    SEL      encodeSelector = @selector(encodeObject:);
 
    if([obj respondsToSelector:cond])
    {
        if(![obj performSelector:cond withObject:owner])
        {
          encodeSelector = @selector(encodeConditionalObject:);
        }
    }
 
    [self performSelector:encodeSelector withObject:obj];
}
 
@end
