//正则匹配用户密码6-20位数字和字母组合
+ (BOOL)checkPassword:(NSString *) password
{
    NSString *pattern =@"(\\w|\\W){6,20}";
    NSPredicate *pred = [NSPredicatepredicateWithFormat:@"SELF MATCHES %@", pattern];
    BOOL isMatch = [predevaluateWithObject:password];
    return isMatch;
}

//正则匹配手机号码
+ (BOOL)isPhoneNumber:(NSString *)mobile
{
    NSString * regex =@"^0?(13[0-9]|15[012356789]|17[678]|18[0-9]|14[57])[0-9]{8}$";
    NSPredicate *pred = [NSPredicatepredicateWithFormat:@"SELF MATCHES %@", regex];
    BOOL isMatch = [predevaluateWithObject:mobile];
    
    return isMatch;
}


//正则匹配邮箱
+ (BOOL) isEmail:(NSString*) checkString {
    
    if([checkStringlength]==0){
        returnNO;
    }
    NSString *regExPattern =@"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";
    
    NSRegularExpression *regEx = [[NSRegularExpressionalloc] initWithPattern:regExPatternoptions:NSRegularExpressionCaseInsensitiveerror:nil];
    NSUInteger regExMatches = [regExnumberOfMatchesInString:checkStringoptions:0range:NSMakeRange(0, [checkStringlength])];
    
    if (regExMatches ==0) {
        returnNO;
