1、手机号

1 2 3 4 5 6

+ (BOOL) IsPhoneNumber:(NSString *)number {     NSString *phoneRegex1=@"1[34578]([0-9]){9}";     NSPredicate *phoneTest1 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",phoneRegex1];     return  [phoneTest1 evaluateWithObject:number]; }

 2、邮箱

1 2 3 4 5 6

+ (BOOL) IsEmailAdress:(NSString *)Email {     NSString *emailCheck = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";     NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES%@",emailCheck];     return [emailTest evaluateWithObject:Email]; }

 3、身份证

1 2 3 4 5 6 7 8 9

+ (BOOL) IsIdentityCard:(NSString *)IDCardNumber {     if (IDCardNumber.length <= 0) {         return NO;     }     NSString *regex2 = @"^(\\d{14}|\\d{17})(\\d|[xX])$";     NSPredicate *identityCardPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regex2];     return [identityCardPredicate evaluateWithObject:IDCardNumber]; }

 4、银行卡
