iOS开发中各种正则匹配

正则匹配

做项目的时候避免不了要用各种的正则匹配，抽空整理了一下，话不多说了，直接上代码

1. 正则匹配手机号

 1. (BOOL)checkTelNumber:(NSString *) telNumber
{
    NSString *pattern = @"^1+[0123456789]+\\d{9}";
    NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", pattern];
    BOOL isMatch = [pred evaluateWithObject:telNumber];
    return isMatch;
}

2. 正则匹配手机号/电话

 1. (BOOL)checkPhoneNumber:(NSString *) telNumber
{
    NSString *pattern = @"^[1-9]+[0123456789]+\\d{9}";
    NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", pattern];
    BOOL isMatch = [pred evaluateWithObject:telNumber];
    return isMatch;
}

3. 正则匹配邮箱

 1. (BOOL) checkEmail:(NSString *)email
{
    NSString *emailRegex = @"[A-Z0-9a-z._%+-][email protected][A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";
    NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
    return [emailTest evaluateWithObject:email];
}

4. 正则匹配用户密码6-16位数字和字母组合

+ (BOOL)checkPassword:(NSString *) password
{
    NSString *pattern = @"^[0-9a-zA-Z_#@]{6,16}";
//    NSString *pattern = @"^(?![0-9]+$)(?![a-zA-Z]+$)[a-zA-Z0-9]{6,16}";
    NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", pattern];
    BOOL isMatch = [pred evaluateWithObject:password];
    return isMatch;
    
}

5. 正则匹配验证码

+ (BOOL)checkVerCode:(NSString *) verCode
{
    NSString *pattern = @"^\\d{4,6}";
    NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", pattern];
    BOOL isMatch = [pred evaluateWithObject:verCode];
    return isMatch;
}

6. 正则匹配用户姓名,20位的中文或英文

 + (BOOL)checkUserName : (NSString *) userName
{
    NSString *pattern = @"^[0-9a-zA-Z\u4E00-\u9FA5]{1,20}";
    NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", pattern];
    BOOL isMatch = [pred evaluateWithObject:userName];
    return isMatch;
    
}

7. 正则匹配标签：中文或英文

 + (BOOL)checkTag : (NSString *) tag
{
    NSString *pattern = @"^[a-zA-Z\u4E00-\u9FA5]{1,10}";
    NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", pattern];
    BOOL isMatch = [pred evaluateWithObject:tag];
    return isMatch;
}

8. 正则匹配用户身份证号15或18位

 + (BOOL)checkUserIdCard: (NSString *) idCard
{
    NSString *pattern = @"(^[0-9]{15}$)|([0-9]{17}([0-9]|X)$)";
    NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", pattern];
    BOOL isMatch = [pred evaluateWithObject:idCard];
    return isMatch;
}

9. 正则匹员工号,12位的数字

+ (BOOL)checkEmployeeNumber : (NSString *) number
{
    NSString *pattern = @"^[0-9]{12}";
    
    NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", pattern];
    BOOL isMatch = [pred evaluateWithObject:number];
    return isMatch;
    
} 

10. 正则匹配URL

+ (BOOL)checkURL : (NSString *) url
{
    NSString *pattern = @"^[0-9A-Za-z]{1,50}";
    NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", pattern];
    BOOL isMatch = [pred evaluateWithObject:url];
    return isMatch;
}
