This question already asked by some people several time. Once again I am asking this question means in iphone any one can't able to implement this feature. 1. If any one can able to implement this pls share your approach with sample code view otherwise write "I cant able to implement this feature in iphone".
If any blog have you enter here but that can't be able to answer properly please clarify with sample code, other wise write "It is not a proper way to implement this feature in iphone". Because your wrong/improper blog creating problem others.
If any one have implemented this feature in IPHONE please tell me the way of approach. This is my request. If you have implemented this feature in iphone then you suggest me the way of approach.
Any help will be accepted greatly.
Thanking you, Andy
