i have array month , year.for ex array {jan 2015,feb 2015, june 2015, september 2015}. want index of current month , getting it. if there no current month, want upcoming recent month.in above example want index of september 2015.

help appreciated.

below code index of current month.

   if ([titlemonth isequaltostring:currentmonth])      {      indexnumber=[[self.databymonth valueforkey:@"title"]indexofobject:currentmonth];      } 

here getting current month nsdate.

create nsdatacomponents

first, need fill array nsdatecomponents objects. @ this method in particular.

for example. create nsdatecomponents current month.

nsdatecomponents *datecomponents = [[nscalendar currentcalendar]components:(nscalendarunitmonth | nscalendarunityear) fromdate:[nsdate date]];  

then fill array these components.

loop through array until current month , year equal or lesser looping month , year. if equal, have current month. if lesser, item in array next month/year.

would work?
here rough sample code

for(nsdatecomponents *components in arrayofmonths) {     if(currentmonth.date == components.date)         nslog(@"current month on list");     else if(currentmonth.date < components.date)     {         nslog(@"this next month on list");         break;     } }
