ios - How to navigate to viewcontrollers from expanded / nested UITableViewCells -
using alex di mango's popdownmenutable-master setup expanding nested uitableviewcell , functioning in project...but issue how navigate other view controllers menu , nested / expanding submenu uitableviewcells...using didselectrowatindexpth programatically created..please refer below code...
