Can't convert from NSString to NSDate

Question

I can't convert my NSString to NSDate. here's the code:

+ (NSDate *) stringToNSDate: (NSString *) dateString{
[NSDateFormatter setDefaultFormatterBehavior:NSDateFormatterBehavior10_4];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss ZZZ"];

NSDate *dateFromString = [dateFormatter dateFromString:dateString];
NSLog(@"dateString: %@ datefromstring: %@", dateString, dateFromString);
return dateFromString;
}

//dateFromString is nil.

What should I do? Thanks!

btw, dateString will always contain a string-ed date in this format: "2012/02/10 08:01:25 +0000"

Answer 1

From the information you've given, the problem appears to be that your dateString separates the date components with slashes ( \\ ), but your date formatter is expecting dashes ( - ).

Edit

To answer your other question, you can use stringByReplacingOccurrencesOfString:withString: .

For example:

NSString *date1 = @"2012/12/10 ...";
NSString *date2 = [date1 stringByReplacingOccurrencesOfString:@"/" withString:@"-"];

Note that this will replace every / with - , so just be careful about timezones etc.

Answer 2

Try this instead:

[dateFormatter setTimeZone:[NSTimeZone timeZoneWithName:@"UTC"]];
[dateFormatter setDateFormat:@"yyyy/MM/dd HH:mm:ss ZZZ"];
