本文提供了使用正则表达式进行电子邮件地址、手机号码及车牌号验证的Objective-C代码示例。通过NSPredicate实现验证功能，适用于iOS应用开发。

    /*邮箱验证 MODIFIED BY HELENSONG*/  
    -(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];  
    }  
      
    /*手机号码验证 MODIFIED BY HELENSONG*/  
    -(BOOL) isValidateMobile:(NSString *)mobile  
    {  
        //手机号以13， 15，18开头，八个 \d 数字字符  
        NSString *phoneRegex = @"^((13[0-9])|(15[^4,\\D])|(18[0,0-9]))\\d{8}$";  
        NSPredicate *phoneTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",phoneRegex];  
    //    NSLog(@"phoneTest is %@",phoneTest);  
        return [phoneTest evaluateWithObject:mobile];  
    }  
      
    /*车牌号验证 MODIFIED BY HELENSONG*/   
    BOOL validateCarNo(NSString* carNo)   
    {   
        NSString *carRegex = @"^[A-Za-z]{1}[A-Za-z_0-9]{5}$";   
        NSPredicate *carTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",carRegex];   
        NSLog(@"carTest is %@",carTest);   
        return [carTest evaluateWithObject:carNo];   
    }
