正则表达式判断姓名（只允许包含中文或英文字母，10个字符以内）的方法：

1 + (BOOL)isValidateName:(NSString *)name {
2     NSString *nameRegex = @"^[\u4E00-\u9FA5A-Za-z]{1,10}";
3     NSPredicate *namePredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", nameRegex];
4     return [namePredicate evaluateWithObject:name];
5 }
