iOS 之常用的正则表达式
在平时的开发中,我们会经常会用到正则去判断,下面是一些我经常使用到的,如有不足,欢迎大家补充
1.创建一个公共的类
//数字
+ (BOOL) validateNumber:(NSString*)number;
//金额
+ (BOOL) validateMoney:(NSString*)money;
//邮箱
+ (BOOL) validateEmail:(NSString *)email;
//手机号码验证
+ (BOOL) validateMobile:(NSString *)mobile;
//车牌号验证
+ (BOOL) validateCarNo:(NSString *)carNo;
//车型
+ (BOOL) validateCarType:(NSString *)CarType;
//用户名
+ (BOOL) validateUserName:(NSString *)name;
//密码
+ (BOOL) validatePassword:(NSString *)passWord;
//昵称
+ (BOOL) validateNickname:(NSString *)nickname;
//身份证号
+ (BOOL) validateIdentityCard: (NSString *)identityCard;
实现方法
+ (BOOL) validateMoney:(NSString*)money{
NSString *moneyRegex = @"^[0-9]+(.[0-9]{2})?$";
NSPredicate *moneyTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", moneyRegex];
return [moneyTest evaluateWithObject:money];
}
//数字
+ (BOOL) validateNumber:(NSString*)number
{
BOOL res = YES;
NSCharacterSet* tmpSet = [NSCharacterSet characterSetWithCharactersInString:@"0123456789"];
int i = 0;
while (i < number.length) {
NSString * string = [number substringWithRange:NSMakeRange(i, 1)];
NSRange range = [string rangeOfCharacterFromSet:tmpSet];
if (range.length == 0) {
res = NO;
break;
}
i++;
}
return res;
}
//邮箱
+ (BOOL) validateEmail:(NSString *)email
{
NSString *emailRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
return [emailTest evaluateWithObject:email];
}
//手机号码验证
+ (BOOL) validateMobile:(NSString *)mobile
{
//手机号以13， 15，18开头，八个 \d 数字字符
//2015/08/25 添加14，17开头
/*

NSString *phoneRegex = @"^((13[0-9])|(14[0-9])|(15[^4,\\D])|(17[0,0-9])|(18[0,0-9]))\\d{8}$";
NSPredicate *phoneTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",phoneRegex];
return [phoneTest evaluateWithObject:mobile];
}
//车牌号验证
+ (BOOL) validateCarNo:(NSString *)carNo
{
NSString *carRegex = @"^[\u4e00-\u9fa5]{1}[a-zA-Z]{1}[a-zA-Z_0-9]{4}[a-zA-Z_0-9_\u4e00-\u9fa5]$";
NSPredicate *carTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",carRegex];

return [carTest evaluateWithObject:carNo];
}
//车型
+ (BOOL) validateCarType:(NSString *)CarType
{
NSString *CarTypeRegex = @"^[\u4E00-\u9FFF]+$";
NSPredicate *carTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",CarTypeRegex];
return [carTest evaluateWithObject:CarType];
}
//用户名
+ (BOOL) validateUserName:(NSString *)name
{
NSString *userNameRegex = @"^[A-Za-z0-9]{6,20}+$";
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}+$";
NSPredicate *passWordPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",passWordRegex];
return [passWordPredicate evaluateWithObject:passWord];
}
//昵称
+ (BOOL) validateNickname:(NSString *)nickname
{
NSString *nicknameRegex = @"^[\u4e00-\u9fa5]{4,8}$";
NSPredicate *passWordPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",nicknameRegex];
return [passWordPredicate evaluateWithObject:nickname];
}
//身份证号
+ (BOOL) validateIdentityCard: (NSString *)identityCard
{
BOOL flag;
if (identityCard.length <= 0) {
flag = NO;
return flag;
}
NSString *regex2 = @"^(\\d{14}|\\d{17})(\\d|[xX])$";
NSPredicate *identityCardPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regex2];
return [identityCardPredicate evaluateWithObject:identityCard];
}
