NSCalendar calendarWithIdentifier throwing error on ios 7

I am creating my app with Xcode 6 and it works fine on ios8. I just tested the app on ios7 and i get this error:

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[NSCalendar calendarWithIdentifier:]: unrecognized selector sent to class 0x3a78418c

This is the code i am using as part of converting dates from Gregorian calendar to Persian Calendar:

NSCalendar *calendar = [NSCalendar calendarWithIdentifier:@"persian"];
Solution

  • The +[NSCalendar calendarWithIdentifier] class method is only available on iOS 8/OS X 10.9 and later.

    But you can use the designated initializer method instead, this works on all iOS releases:

    NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:@"persian"];
