Question

我试图证实代表地方名的扼杀。我正对这样的一套简单特性加以匹配。

NSString *regexName = @"[a-zA-Z][., a-zA-Z\t\-]*"
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", regexName];

I would like to know simple regular expression to use to match a broader international character set (principally western characters). I could just enumerate every character I can think of inside the regular expression, but I imagine there is another way. I m looking for ideas.

docs ,列出了一些选择。

您正在研究的是公文财产,其编号为p{Letter}。 (或简而言之,p{L})。

这里,任何想要在实践中看到这种习俗的人都有一些守则:

NSArray *strings = [NSArray arrayWithObjects:
                           @"Joe",
                           @"Chloë",
                           @"Søren",
                           @"Renée",
                           @"Se7en",
                           @"Zürich",
                           @"Genève",
                           @"Tromsø",
                           @"Jane",
                           nil];

NSString *regexName = @"\p{Letter}[., \p{Letter}\t\-]*";

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", regexName];

NSArray *filteredArray = [strings filteredArrayUsingPredicate:predicate];

它把所有名字与信件相匹配,但不是“Se7en”。

问题提到西方特征,但使用其他字母的语文的例子也是一样的。
