ios 正則表達式之驗證手機號、郵箱、身份證、銀行卡

1、手機號

123456 + (BOOL) IsPhoneNumber:(NSString *)number{ NSString *phoneRegex1=@"1[34578]([0-9]){9}"; NSPRedicate *phoneTest1 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",phoneRegex1]; return [phoneTest1 evaluateWithObject:number];}

2、郵箱

123456 + (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、身份證

123456789 + (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、銀行卡

123456789101112131415161718192021222324252627282930313233343536373839 + (BOOL) IsBankCard:(NSString *)cardNumber{ if(cardNumber.length==0) { return NO; } NSString *digitsOnly = @""; char c; for (int i = 0; i < cardNumber.length; i++) { c = [cardNumber characterAtIndex:i]; if (isdigit(c)) { digitsOnly =[digitsOnly stringByAppendingFormat:@"%c",c]; } } int sum = 0; int digit = 0; int addend = 0; BOOL timesTwo = false; for (NSInteger i = digitsOnly.length - 1; i >= 0; i--) { digit = [digitsOnly characterAtIndex:i] - '0'; if (timesTwo) { addend = digit * 2; if (addend > 9) { addend -= 9; } } else { addend = digit; } sum += addend; timesTwo = !timesTwo; } int modulus = sum % 10; return modulus == 0;}
