上面的正则表达式实际书写时需把一个反斜杠替换成两个反斜杠，如匹配E-Mail时要写成

NSString
*regex = @
"\\b([a-zA-Z0-9%_.+\\-]+)@([a-zA-Z0-9.\\-]+?\\.[a-zA-Z]{2,6})\\b"
;
NSLog
(@
"Regex: %@"
,regex);
if
([@
"unmi@scalau.com"
isMatchedByRegex:regex]){
"Valid email address"
);
}

Regex: \b([a-zA-Z0-9%_.+\-]+)@([a-zA-Z0-9.\-]+?\.[a-zA-Z]{2,6})\b
Valid email address
这和Java的正则表达式一样，也就是要写成NSLog输出的样子，也就是转义的转义，如果是 \-或 \.编译时会提示：
Lexical or Preprocessor Issue Unknown escape sequence "\."
Lexical or Preprocessor Issue Unknown escape sequence "\-"
但执行时不会报错，只是匹配不成功.
