//手機號碼的正則表達式
- (BOOL)isValidateMobile:(NSString *)mobile{
//手機號以13、15、18開頭，八個\d數字字符
NSString *phoneRegex = @"^((13[0-9])|(15[^4,\\D])|(18[0,0-9]))\\d{8}$";
NSPredicate *phoneTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",phoneRegex];
return [phoneTest evaluateWithObject:mobile];
}

//郵箱地址的正則表達式
- (BOOL)isValidateEmail:(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];
}
