IOS 常用正则表达式整理（邮箱、身份证号、固化、手机号、纯数字、纯文字等）

前言：常用正则表达式整理，包括邮箱、身份证号、固化、手机号、纯数字、纯文字等

一、对邮箱进行校验

+ (BOOL)checkEmail:(NSString *)email
{
NSString *emailReg = @"^([a-z0-9A-Z]+[-|\\.]?)+[a-z0-9A-Z]@([a-z0-9A-Z]+(-[a-z0-9A-Z]+)?\\.)+[a-zA-Z]{2,}$";
NSPredicate *regextestmobile = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",emailReg];
if ([regextestmobile evaluateWithObject:email] == YES){
return YES;
}
return NO;
}

二、对身份证号进行校验

+ (BOOL)checkPersonID:(NSString *)personID
{
NSString *person = @"(\\d{14}[0-9a-zA-Z])|(\\d{17}[0-9a-zA-Z])";
NSPredicate *regextestmobile = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",person];
if ([regextestmobile evaluateWithObject:personID] == YES){
return YES;
}
return NO;
}

三、对固话进行校验

#pragma mark 检验是否是固定电话
+ (BOOL)checkLandlinePhone:(NSString *)landlinePhone
{
NSString *mobile = @"0\\d{2,3}-\\d{5,9}|0\\d{2,3}-\\d{5,9}";
NSPredicate *regextestmobile = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",mobile];
if ([regextestmobile evaluateWithObject:landlinePhone] == YES){
return YES;
}
return NO;
}

四、对手机号进行校验

#pragma mark 检测手机号码是否正确
+ (BOOL)checkMobileNumber:(NSString *)mobileNum{
mobileNum = [mobileNum stringByReplacingOccurrencesOfString:@"-" withString:@""];
mobileNum = [mobileNum stringByReplacingOccurrencesOfString:@" " withString:@""];
if ([mobileNum hasPrefix:@"00"])
return NO;

if ([mobileNum hasPrefix:@" "]){
mobileNum = [mobileNum stringByReplacingOccurrencesOfString:@" " withString:@""];
}

NSString * MOBILE = @"^1(3[0-9]|4[0-9]|5[0-9]|7[67]|8[0-9])\\d{8}$";

28         */

NSString *telNum = @"^0\\d[1-9]{1}(\\d[0-9]{1,2}\\d[1-9]{1})\\d{4,6}";
NSPredicate *regextestmobile = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", MOBILE];
NSPredicate *regextestcm = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CM];
NSPredicate *regextestcu = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CU];
NSPredicate *regextestct = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CT];
NSPredicate *regextestTel = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", telNum];
if ([regextestTel evaluateWithObject:mobileNum]){
MyLog(@"pass");
}
if (([regextestmobile evaluateWithObject:mobileNum] == YES)
|| ([regextestcm evaluateWithObject:mobileNum] == YES)
|| ([regextestct evaluateWithObject:mobileNum] == YES)
|| ([regextestcu evaluateWithObject:mobileNum] == YES)
|| ([regextestTel evaluateWithObject:mobileNum] == YES)){
return YES;
}
return NO;
}

五、纯数字

NSString *reg = @"^\\d*$";六、纯字母
NSString *reg = @"^[A-Za-z]*$";七、首字母为字母，其它为A-Za-z_0-9

NSString *reg = @"^[a-zA-Z]\\w{1,}$";
