ios使用常用正则表达式验证密码身份证手机号

#pragma 正则匹配手机号
+ (BOOL)checkTelNumber:(NSString *) telNumber
{
    NSString *pattern = @^1+[3578]+d{9};
    NSPredicate *pred = [NSPredicate predicateWithFormat:@SELF MATCHES %@, pattern];
    BOOL isMatch = [pred evaluateWithObject:telNumber];
    return isMatch;
}
 
 
#pragma 正则匹配用户密码6-18位数字和字母组合
+ (BOOL)checkPassword:(NSString *) password
{
    NSString *pattern = @^(?![0-9]+$)(?![a-zA-Z]+$)[a-zA-Z0-9]{6,18};
    NSPredicate *pred = [NSPredicate predicateWithFormat:@SELF MATCHES %@, pattern];
    BOOL isMatch = [pred evaluateWithObject:password];
    return isMatch;
     
}
 
#pragma 正则匹配用户姓名,20位的中文或英文
+ (BOOL)checkUserName : (NSString *) userName
{
    NSString *pattern = @^[a-zA-Z一-龥]{1,20};
    NSPredicate *pred = [NSPredicate predicateWithFormat:@SELF MATCHES %@, pattern];
    BOOL isMatch = [pred evaluateWithObject:userName];
    return isMatch;
     
}
 
 
#pragma 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;

#pragma 正则匹员工号,12位的数字
+ (BOOL)checkEmployeeNumber : (NSString *) number

    NSPredicate *pred = [NSPredicate predicateWithFormat:@SELF MATCHES %@, pattern];
    BOOL isMatch = [pred evaluateWithObject:number];
    return isMatch;

#pragma 正则匹配URL
+ (BOOL)checkURL : (NSString *) url
{

    NSPredicate *pred = [NSPredicate predicateWithFormat:@SELF MATCHES %@, pattern];
