Traverse all access points in Symbian and dynamically display them in popupsettingitem)

In network connection selection, we usually traverse existing access points in the user's mobile phone, and then select an appropriate access point to connect to the network. Because the number of existing access points in each mobile phone is different, dynamic reading and existing access points are required. Therefore, you can inherit caknenumeratedtextpopupsettingitem, overload the completeconstructionl () method, and implement it in caknsettingitemlist,
