Question

Answer 1

Not fully verified this, but he has to do the trick.

NSDateFormatter *formatter = [[NSDateFormatter alloc] initWithDateFormat:@"EEE, dd MMM yyyy HH:mm:ss ZZZ" allowNaturalLanguage:NO];
NSDate *date = [formatter dateWithString:@"Mon, 01 Feb 2010 20:25:37 +0000"];

Answer 2

Use +[NSDate dateWithString:]if format is " 2001-03-24 10:45:32 +0600".

If not, you need to build NSDateFormatterand then use -[NSDateFormatter dateFromString:].
