正则表达式
**身份证验证：
方式一：只能判断18位身份证：但是方法优于方法二**

+ (BOOL)checkIdentityCardNo:(NSString*)cardNo{    if (cardNo.length != 18) {        return  NO;    }    NSArray* codeArray = [NSArray arrayWithObjects:@"7",@"9",@"10",@"5",@"8",@"4",@"2",@"1",@"6",@"3",@"7",@"9",@"10",@"5",@"8",@"4",@"2", nil];    NSDictionary* checkCodeDic = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:@"1",@"0",@"X",@"9",@"8",@"7",@"6",@"5",@"4",@"3",@"2", nil]  forKeys:[NSArray arrayWithObjects:@"0",@"1",@"2",@"3",@"4",@"5",@"6",@"7",@"8",@"9",@"10", nil]];    NSScanner* scan = [NSScanner scannerWithString:[cardNo substringToIndex:17]];    int val;    BOOL isNum = [scan scanInt:&val] && [scan isAtEnd];    if (!isNum) {        return NO;    }    int sumValue = 0;    for (int i =0; i<17; i++) {        sumValue+=[[cardNo substringWithRange:NSMakeRange(i , 1) ] intValue]* [[codeArray objectAtIndex:i] intValue];    }    NSString* strlast = [checkCodeDic objectForKey:[NSString stringWithFormat:@"%d",sumValue%11]];    if ([strlast isEqualToString: [[cardNo substringWithRange:NSMakeRange(17, 1)]uppercaseString]]) {        return YES;    }    return  NO;}

方式二：判断18位15位身份证

+ (BOOL)PINpersonalIdentificationNumber:(NSString *) textString{    NSString* number=@"(\\d{14}[0-9a-zA-Z])|(\\d{17}[0-9a-zA-Z])";    NSPredicate *numberPre = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",number];    if ([numberPre evaluateWithObject:textString]) {        NSRange range1 = NSMakeRange(0, 1);        NSInteger one = [[textString substringWithRange:range1] integerValue];        if (one < 9 && one > 0) {            NSRange range2 = NSMakeRange(1, 1);            NSInteger two = [[textString substringWithRange:range2] integerValue];            if (two < 8 && two >= 0) {                NSRange range3 = NSMakeRange(6, 4);                NSString *year = [textString substringWithRange:range3];                NSRange range4 = NSMakeRange(10, 2);                NSString *month = [textString substringWithRange:range4];                NSRange range5 = NSMakeRange(12, 2);                NSString *day = [textString substringWithRange:range5];                NSString *DateText = [NSString stringWithFormat:@"%@-%@-%@",year,month,day];                NSString *Date = @"(([0-9]{3}[1-9]|[0-9]{2}[1-9][0-9]{1}|[0-9]{1}[1-9][0-9]{2}|[1-9][0-9]{3})-(((0[13578]|1[02])-(0[1-9]|[12][0-9]|3[01]))|((0[469]|11)-(0[1-9]|[12][0-9]|30))|(02-(0[1-9]|[1][0-9]|2[0-8]))))|((([0-9]{2})(0[48]|[2468][048]|[13579][26])|((0[48]|[2468][048]|[3579][26])00))-02-29)";                NSPredicate *numberPre1 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",Date];                if ([numberPre1 evaluateWithObject:DateText]) {                    return YES;                }else{                    return NO;                }            }else{                return NO;            }        }else{            return NO;        }    }else{        return NO;    }}

日期验证：
闰年的2月份有29天，因此匹配闰年日期格式为YYYY-MM-DD的正则表达式为：

(([0-9]{2})(0[48]|[2468][048]|[13579][26])|((0[48]|[2468][048]|[3579][26])00))-02-29

最后，将平年和闰年的日期验证表达式合并，我们得到最终的验证日期格式为YYYY-MM-DD的正则表达式为：

(([0-9]{3}[1-9]|[0-9]{2}[1-9][0-9]{1}|[0-9]{1}[1-9][0-9]{2}|[1-9][0-9]{3})-(((0[13578]|1[02])-(0[1-9]|[12][0-9]|3[01]))|((0[469]|11)-(0[1-9]|[12][0-9]|30))|(02-(0[1-9]|[1][0-9]|2[0-8]))))|((([0-9]{2})(0[48]|[2468][048]|[13579][26])|((0[48]|[2468][048]|[3579][26])00))-02-29)

DD/MM/YYYY格式的正则验证表达式为：

(((0[1-9]|[12][0-9]|3[01])/((0[13578]|1[02]))|((0[1-9]|[12][0-9]|30)/(0[469]|11))|(0[1-9]|[1][0-9]|2[0-8])/(02))/([0-9]{3}[1-9]|[0-9]{2}[1-9][0-9]{1}|[0-9]{1}[1-9][0-9]{2}|[1-9][0-9]{3}))|(29/02/(([0-9]{2})(0[48]|[2468][048]|[13579][26])|((0[48]|[2468][048]|[3579][26])00)))

电话号码验证：

+ (BOOL) isMobile:(NSString *)mobileNumbel{    /**     * 手机号码     * 移动：134[0-8],135,136,137,138,139,150,151,157,158,159,182,187,188     * 联通：130,131,132,152,155,156,185,186     * 电信：133,1349,153,180,189,181(增加)     */    NSString * MOBIL = @"^1(3[0-9]|5[0-35-9]|8[025-9])\\d{8}$";    /**     10         * 中国移动：China Mobile     11         * 134[0-8],135,136,137,138,139,150,151,157,158,159,182,187,188     12         */    NSString * CM = @"^1(34[0-8]|(3[5-9]|5[017-9]|8[2378])\\d)\\d{7}$";    /**     15         * 中国联通：China Unicom     16         * 130,131,132,152,155,156,185,186     17         */    NSString * CU = @"^1(3[0-2]|5[256]|8[56])\\d{8}$";    /**     20         * 中国电信：China Telecom     21         * 133,1349,153,180,189,181(增加)     22         */    NSString * CT = @"^1((33|53|8[019])[0-9]|349)\\d{7}$";    NSPredicate *regextestmobile = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", MOBIL];    NSPredicate *regextestcm = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CM];    NSPredicate *regextestcu = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CU];    NSPredicate *regextestct = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CT];    if (([regextestmobile evaluateWithObject:mobileNumbel]         || [regextestcm evaluateWithObject:mobileNumbel]         || [regextestct evaluateWithObject:mobileNumbel]         || [regextestcu evaluateWithObject:mobileNumbel])) {        return YES;    }    return NO;}
