Question

I am having problems with NSDateFormatter‘s dateFromString method.

I have the following date: Tue, 12 Jul 2011 20:18:26 GMT , but NSDateFormatter doesn’t seem to recognize it and returns (null).

Here’s what I tried:

    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"dd/MM/yyyy HH:MM:SS"];
    NSDate *date = [dateFormatter dateFromString:@"Tue, 12 Jul 2011 20:18:26 GMT"];
    [dateFormatter release];

    NSLog(@"Date: %@",date);

What am I doing wrong?

Answer 1

In this case you need to set dateFormat to match the format of the date in the string. Try following:

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"ddd, dd MMM YYYY HH:MM:SS ZZZ"];
NSDate *date = [dateFormatter dateFromString:@"Tue, 12 Jul 2011 20:18:26 GMT"];
[dateFormatter setDateFormat:@"dd/MM/yyyy HH:MM:SS"];
NSString *newFormattedDate = [dateFormatter stringFromDate:date];

NSLog(@"Date: %@ || %@",datem newFormattedDate);
