60*60 is 3600 seconds from now, so logically:
notification.fireDate = [NSDate dateWithTimeIntervalSinceNow:60 * 120];
Which will fire every two hours, for more information on dateWithTimeIntervalSinceNow
see the NSDate Class Reference
Frage
I need to make a NSDate
to set a local notification so it fires every 2 hours or well at every specific time.
I don't know how to do this though, so it will be greatly appreciated if someone can show me how...
I saw something like this but I don't know how it works:
notification.fireDate = [NSDate dateWithTimeIntervalSinceNow:60 * 60];
