Date formatter is not working in iOS6, but working perfectly in iOS 7

Question

Processing a date string in the format: June 12, 2014 - 19:35:51 UTC.

NSString * dateStr = @"June 12, 2014 - 19:35:51 UTC";
NSDateFormatter * dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setTimeZone:[NSTimeZone timeZoneWithName:@"UTC"]];
[dateFormatter setDateFormat:@"MMMM dd, yyyy - HH:mm:ss Z"];
NSDate *startTime = [dateFormatter dateFromString: dateStr];

This works perfectly in iOS7, not in iOS6 getting nil.

Answer 1

Try setting the locale like this:

[dateFormatter setLocale:[[NSLocale alloc] initWithLocaleIdentifier:@"en_US"]];
