Question

I’m trying to create an NSDate with dateWithTimeIntervalSince1970 but I keep getting an NSInvalidArgumentException. I can’t figure out what’s wrong with my syntax:

// [mutableItem valueForKey:@"date"] is a string which represents an integer of milliseconds

NSDate *dateObject = [NSDate dateWithTimeIntervalSince1970:([[mutableItem valueForKey:@"date"] longLongValue]/1000)];

Can anyone see what’s wrong with this?

Answer 1

Can you check your mutableItem value?

Here’s my working example:

NSString *mutableItem = @"1344981600000";

NSDate *dateObject = [NSDate dateWithTimeIntervalSince1970:([mutableItem longLongValue]/1000)];

//dateObject = 2012-08-14 22:00:00 +0000
