Re: Providing replicable views in IB

You can implement copying of a view by archiving and immediately 
unarchiving the root view.

Something like this (written on the phone, don't expect this to parse 
correctly immediately):

-(id)copyWithZone:(NSZone *)zone {
      return [NSKeyedUnarchiver unarchiveObjectWithData:
[NSKeyedArchiver archiveDataWithRootObject:self]];
}
