Apple audit rejects any app using DDL. I think there is security issue with DDL by which one process/app may intrude other processes/apps' address space at run time. SNS implementation in iOS provides a uniform interface - UIActivityViewController+UIActivity which implemented most common parts, each SN just needs add a thin layer with their own logic, graphics, etc. I do not know why Apple has not provided an Ads interface/API as SNS, hope they will.
