Question

I am trying to convert a NSString into a double using the following:

double lastSynced;
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
               [dateFormatter setDateFormat:@"YYYY-MM-DD HH:MM:SS"];
               NSDate *dateFromString = [[NSDate alloc] init];
               dateFromString = [dateFormatter dateFromString:@"2012-03-28 18:41:25"];
               lastSynced = [dateFromString timeIntervalSince1970];

However when printing lastSynced it always gives me 0. Why is this?

Answer 1

Your date format is wrong. Should be:

[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
