Regex for email address

Question

Can someone show me a sample RegEx for an email address and how to use in in Objective-C?

Looking for something that fits: name@place.something

Answer 1

NSString *string= @"my@mail.com her@mail.com him@mail.com";
NSError *error = NULL;
NSRegularExpression *regex = nil;
regex = [NSRegularExpression regularExpressionWithPattern:@"\\w+@[a-zA-Z_]+?\\.[a-zA-Z]{2,6}"
                                                  options:NSRegularExpressionCaseInsensitive
                                                    error:&error];   
NSUInteger numberOfMatches = 0;
numberOfMatches = [regex numberOfMatchesInString:string
                                         options:0
                                           range:NSMakeRange(0, [string length])];
NSLog(@"numberOfMatches is: %lu", numberOfMatches);

There are more options of course. Read here.
