Question

I have issues with date parsing. It works on my devices and simulator, but not on client device (which is also iPhone iOS 5.1.1, but maybe a different configuration)

    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    NSDate          *date = nil;
    NSError         *error = nil; 

    [formatter setDateFormat:@"EEE, dd MMM y HH:mm:ss zzz"];
    if (![formatter getObjectValue:&date forString:@"Mon, 21 Jun 2012 21:21:21 GMT" range:nil error:&error])
    {
        NSLog(@"%@", error);
    }

which outputs

Error Domain=NSCocoaErrorDomain Code=2048 "The operation couldn’t be completed. (Cocoa error 2048.)" UserInfo=0x446f10 {NSInvalidValue=Mon, 21 Jun 2012 21:21:21 GMT}

You need to set the locale on the date formatter to en_US_POSIX.

formatter.locale = [[NSLocale alloc] initWithLocaleIdentifier:@"en_US_POSIX"];
