The use of the nspredicate of Objective-c grammar

Regular expressions determine the phone number and phone number method:

The regular expression determines the name (only the Chinese or English letters are allowed, within 10 characters) of the method:

1 + (BOOL) Isvalidatename: (NSString *) name {2     @ "^[\u4e00-\u9fa5a-za-z]{ 1,10}"; 3     Nspredicate *namepredicate = [nspredicate predicatewithformat:@ "selfMATCHES%@" , Nameregex]; 4     return [Namepredicate evaluatewithobject:name]; 5 }
