ios 7.1 Crash when tap on More button on tab bar -


i got crash bug on when tap on more button on tabbar. happened on ios 7.1.

i created class (moretableviewdelegate) override uitableviewdelegate of more table view

morenavigationcontroller uiviewcontroller *moreviewcontroller =       tabbarcontroller.morenavigationcontroller.topviewcontroller;  uitableview *moretableview = (uitableview*)moreviewcontroller.view;  moretableviewdelegate *objmoredelegate=[[moretableviewdelegate alloc]initwithdelegate:moretableview.delegate];  moretableview.delegate=objmoredelegate;

this detail of moretableviewdelegate:

-(moretableviewdelegate *) initwithdelegate:(id<uitableviewdelegate>) delegate {  originaldelegate=delegate; [super init];       return self; }  - (cgfloat)tableview:(uitableview *)tableview heightforrowatindexpath:(nsindexpath *)indexpath  {        if(ispoweredbymobicart==yes)    {         return 50;     } else  {        return 60;      }  }      - (void)tableview:(uitableview *)tableview didselectrowatindexpath:(nsindexpath *)indexpath  { return [originaldelegate tableview:tableview didselectrowatindexpath:indexpath]; }

but when tap on more button @ tab bar, it's crashed , log:
