正则表达式验证用户名、密码、手机号码、身份证(推荐)

废话不多说了,下面给大家介绍使用正则表达式验证用户名、密码、手机号码、身份证的写法,需要的的朋友参考下吧

//用户名

+ (BOOL) validateUserName:(NSString *)name

{

NSString *userNameRegex = @"^[A-Za-z0-9]{3,20}+$";

NSPredicate *userNamePredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",userNameRegex];

BOOL B = [userNamePredicate evaluateWithObject:name];

return B;

}

//密码

+ (BOOL) validatePassword:(NSString *)passWord

{

NSString *passWordRegex = @"^[a-zA-Z0-9]{6,20}+$";

NSPredicate *passWordPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",passWordRegex];

return [passWordPredicate evaluateWithObject:passWord];

}

//判断手机号码格式是否正确

+ (BOOL)valiMobile:(NSString *)mobile

{

mobile = [mobile stringByReplacingOccurrencesOfString:@" " withString:@""];

if (mobile.length != 11)

{

return NO;

}else{

/**

* 移动号段正则表达式

*/

NSString *CM_NUM = @"^((13[4-9])|(147)|(15[0-2,7-9])|(178)|(18[2-4,7-8]))\\d{8}|(1705)\\d{7}$";

/**

* 联通号段正则表达式

*/

NSString *CU_NUM = @"^((13[0-2])|(145)|(15[5-6])|(176)|(18[5,6]))\\d{8}|(1709)\\d{7}$";

/**

* 电信号段正则表达式

*/

NSString *CT_NUM = @"^((133)|(153)|(177)|(18[0,1,9]))\\d{8}$";

NSPredicate *pred1 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CM_NUM];

BOOL isMatch1 = [pred1 evaluateWithObject:mobile];

NSPredicate *pred2 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CU_NUM];

BOOL isMatch2 = [pred2 evaluateWithObject:mobile];

NSPredicate *pred3 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CT_NUM];

BOOL isMatch3 = [pred3 evaluateWithObject:mobile];

if (isMatch1 || isMatch2 || isMatch3) {

return YES;

}else{

return NO;

}

}

}

/**

* 验证身份证号码是否正确的方法

*

* @param IDNumber 传进身份证号码字符串

*

* @return 返回YES或NO表示该身份证号码是否符合国家标准

*/

+ (BOOL)isCorrect:(NSString *)IDNumber

{

NSMutableArray *IDArray = [NSMutableArray array];

// 遍历身份证字符串,存入数组中

if (IDNumber.length == 18) {

for (int i = 0; i < 18; i++) {

NSRange range = NSMakeRange(i, 1);

NSString *subString = [IDNumber substringWithRange:range];

[IDArray addObject:subString];

}

}else{

for (int i = 0; i < 15; i++) {

NSRange range = NSMakeRange(i, 1);

NSString *subString = [IDNumber substringWithRange:range];

[IDArray addObject:subString];

}

}

// 系数数组

NSArray *coefficientArray = [NSArray arrayWithObjects:@"7", @"9", @"10", @"5", @"8", @"4", @"2", @"1", @"6", @"3", @"7", @"9", @"10", @"5", @"8", @"4", @"2", nil];

// 余数数组

NSArray *remainderArray = [NSArray arrayWithObjects:@"1", @"0", @"X", @"9", @"8", @"7", @"6", @"5", @"4", @"3", @"2", nil];

// 每一位身份证号码和对应系数相乘之后相加所得的和

int sum = 0;

if (IDNumber.length == 18) {

for (int i = 0; i < 17; i++) {

int coefficient = [coefficientArray[i] intValue];

int ID = [IDArray[i] intValue];

sum += coefficient * ID;

}

}else{

for (int i = 0; i < 14; i++) {

int coefficient = [coefficientArray[i] intValue];

int ID = [IDArray[i] intValue];

sum += coefficient * ID;

}

}

// 这个和除以11的余数对应的数

NSString *str = remainderArray[(sum % 11)];

// 身份证号码最后一位

NSString *string;

if (IDNumber.length == 18) {

string = [IDNumber substringFromIndex:17];

}else{

string = [IDNumber substringFromIndex:14];

}

// 如果这个数字和身份证最后一位相同,则符合国家标准,返回YES

if ([str isEqualToString:string]) {

return YES;

} else {

return NO;

}

}
