There was a beautiful and peaceful planet in the other space which paralleled our space.

Everyone on this planet lived happily under super baby pig’s protection.

One day, an evil organization from other space intruded this planet and destroyed it.

Heroical super baby pig stood and fought for people’s happiness.

However, the devil had special power which could depress super baby pig’s super power.

Super baby pig cooperated with the scientists to send signals to our earth through special communicator and hope earthmen could assist super baby pig through smart phone.

Please turn on your smart phone and enter the world of super baby pig!

Super baby pig was waiting for the assistance from the friends of earth.

Super baby pig and scientists had found four bad guys currently but the bad guys used technology to seal off the area. Super baby pig and scientists tried their great effort to unlock an area and had to collect the blue energy money while chasing the bad guys in order to have enough power to destroy their protection cover and unlock more areas.

According to the scientists’ investigation, the bad guys were riding heavy –duty motorcycles and wreaking in the desert area. Please help super baby pig to arrest them, friends from earth!

Super baby pig’s planet had consumed the most of resources to defend the bad buys. Please supply resources to help super baby pig protect their planet if earthmen wanted.

There was a beautiful place called Taiwan on the earth. A beautiful girl was wakeful and wanted to play games.

Mira：『So boring and wakeful. Let’s play some games.』

Mira：『Mm……What to play?』

Mira：『What’s it? SOS?』

Mira：『Let me see what it is. How come there is SOS from my smart phone.』

BabyPig：『Hello, it’s super baby pig. Our planet was intruded and we need your help.』

Mira：『Hello, super baby pig. How can I help you?』

BabyPig：『Our scientist developed a game which is slotted on App Store and Google Play. You can use the game to help me.』

Mira：『Ok, let me download it.』

Mira：『I found it. That’s it.』

BabyPig：『Thank you. Please give me indications to help me fight the bad guys.』

Mira：『The bad guy is so formidable. What should I do?』

BabyPig：『You can get the blue energy money from the store and use it to make baby’s bottle which can recover my super power for short period.』

Mira：『Let me check. I found it. That’s it. Let’s try again.』

Mira：『Yeah! I passed it and arrested the bad buy. Super baby pig is so cute. Let’s play this cute game together!』

[C#] Generic Singleton Pattern

2011-06-08T20:55:00.000-07:00

C# singleton pattern with generic.
Why need using generic singleton?
If we use an interface named ISingleton, and provide an Instance property, we must implement in all derived class.
Or we need to provide Instance property in all singleton class.
That is a trouble, so we use generic to solute it
Because singleton need provide private or protected constructor, so we can't use new T() in generic singleton pattern.
So we need to use reflection to call constructor.

using System;
using System.Collections.Generic;
using System.Text;
using System.Reflection;

namespace DesignPattern
{
  public class TSingleton<T> where T : class
  {
      static object SyncRoot = new object();
      static T instance;
      public static readonly Type[] EmptyTypes = new Type[0];
      public static T Instance
      {
          get
          {
              if (instance == null)
              {
                  lock (SyncRoot)
                  {
                      if (instance == null)
                      {
                          ConstructorInfo ci = typeof(T).GetConstructor(BindingFlags.NonPublic | BindingFlags.Instance, null, EmptyTypes, null);
                          if (ci == null) { throw new InvalidOperationException("class must contain a private constructor"); }
                          instance = (T)ci.Invoke(null);
                          //instance = Activator.CreateInstance(typeof(T)) as T;
                      }
                  }
              }
              return instance;
          }
      }
  }

[IPhone] Send SMS sample with IPhone

2010-12-02T22:36:00.000-08:00

Introduction

I will demo some sample to present how to send SMS in iphone programming.

Sample 1

The easiest way is this demo.

[[UIApplication sharedApplication] openURL: @"sms:12345678"];

HTML links:  
<a href="sms:" mce_href="sms:">Launch Text Application</a>   
<a href="sms:1-408-555-1212" mce_href="sms:1-408-555-1212">New SMS Message</a>   
 
Native application URL strings:  
 
sms:   
sms:1-408-555-1212

Sample 2

We can use MessageUI Framework and MFMessageComposeViewController to send SMS.

-(IBAction) sendInAppSMS:(id) sender
{
    MFMessageComposeViewController *controller = [[[MFMessageComposeViewController alloc] init] autorelease];
    if([MFMessageComposeViewController canSendText])
    {
        controller.body = @"Hello from Mugunth";
        controller.recipients = [NSArray arrayWithObjects:@"12345678", @"87654321", nil];
        controller.messageComposeDelegate = self;
        [self presentModalViewController:controller animated:YES];
    }
}

You have to handle a callback method of MFMessageComposeViewControllerDelegate so as to dismiss the modal view controller.

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
    switch (result) {
        case MessageComposeResultCancelled:
            NSLog(@"Cancelled");
            break;
        case MessageComposeResultFailed:
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"MyApp" message:@"Unknown Error"
                                                           delegate:self cancelButtonTitle:@”OK” otherButtonTitles: nil];
            [alert show];
            [alert release];
            break;
        case MessageComposeResultSent:

            break;
        default:
            break;
    }

    [self dismissModalViewControllerAnimated:YES];
}

[IPhone] Remind to rank/review sample code

2010-11-28T04:40:00.000-08:00

Introduction

How can we remind user to review or rank in App?
We can show a alert box to remind user to review, I writed a sample code using singleton to remind user.

How to use

CloudReview.h

#import <Foundation/Foundation.h>

       _sharedReview = [super alloc];
       return _sharedReview;
   }
  
   return nil;
}

-(void)reviewFor:(int)appleID

   m_appleID = appleID;
   BOOL neverRate = [[NSUserDefaults standardUserDefaults] boolForKey:@"neverRate"];
   if(neverRate != YES) {
       //Show alert here
       UIAlertView *alert;
       alert = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"rate_title",@"Rate My Appication")

[Design Pattern] MVC pattern

2010-11-10T21:55:00.001-08:00

Model–View–Controller (MVC) is a software architecture,[1] currently considered an architectural pattern used in software engineering. The pattern isolates "domain logic" (the application logic for the user) from the user interface (input and presentation), permitting independent development, testing and maintenance of each (separation of concerns).

The model manages the behavior and data of the application domain, responds to requests for information about its state (usually from the view), and responds to instructions to change state (usually from the controller). In event-driven systems, the model notifies observers (usually views) when the information changes so that they can react.

The view renders the model into a form suitable for interaction, typically a user interface element. Multiple views can exist for a single model for different purposes. A viewport typically has a one to one correspondence with a display surface and knows how to render to it.

The controller receives input and initiates a response by making calls on model objects. A controller accepts input from the user and instructs the model and viewport to perform actions based on that input.

An MVC application may be a collection of model/view/controller triads, each responsible for a different UI element. The Swing GUI system, for example, models almost all interface components as individual MVC systems.

MVC is often seen in web applications where the view is the HTML or XHTML generated by the app. The controller receives GET or POST input and decides what to do with it, handing over to domain objects (i.e. the model) which contain the business rules and know how to carry out specific tasks such as processing a new subscription, and which hand control to (X)HTML-generating components such as templating engines, XML pipelines, AJAX callbacks, etc.

The model is not a database: the 'model' in MVC is both the data and the business/domain logic needed to manipulate the data in the application. Many applications use a persistent storage mechanism such as a database to store data. MVC does not specifically mention the data access layer because it is understood to be underneath or encapsulated by the model. Models are not data access objects; however, in very simple apps that have little domain logic there is no real distinction to be made. Active Record is an accepted design pattern which merges domain logic and data access code - a model which knows how to persist itself.

[Design Pattern] Facade Pattern

2010-11-10T21:51:00.000-08:00

The facade pattern is a software engineering design pattern commonly used with Object-oriented programming. (The name is by analogy to an architectural facade.)

A facade is an object that provides a simplified interface to a larger body of code, such as a class library. A facade can:

make a software library easier to use, understand and test, since the facade has convenient methods for common tasks;
make code that uses the library more readable, for the same reason;
reduce dependencies of outside code on the inner workings of a library, since most code uses the facade, thus allowing more flexibility in developing the system;
wrap a poorly-designed collection of APIs with a single well-designed API (as per task needs).

[C++] Hex string convert to integer with stringstream

2010-09-07T09:00:00.000-07:00

Sometimes we need to convert hex string to integer.
Usually we will use this alrorithm.

char xtod(char c) {
 if (c>='0' && c<='9') return c-'0';
 if (c>='A' && c<='F') return c-'A'+10;
 if (c>='a' && c<='f') return c-'a'+10;
 return c=0;        // not Hex digit
}

This is a conventional usage.
Tonight I found a question in CSDN, then I try to found a better solution.
In stackoverflow, I found this answer.
It is very nice.

#include <sstream>
#include <iostream>

int main() {
  unsigned int x; 
  std::stringstream ss;
  ss << std::hex << "FF";
  ss >> x;
  // output it as a signed type
  std::cout << static_cast<int>(x) << std::endl;
}

[C] OOP in C sample

2010-08-20T10:39:00.000-07:00

Because I got a job, it was a C project.
So I am learning how to implement OOP in C now.
This is a example searched form google.
I use Xcode 3.2.3 with gcc4.2 to implement and test it.

#include <stdio.h>
#include <stdlib.h>

typedef void (*Walk_Fun)(struct Animal *a_This);
typedef struct Animal * (*Dtor_Fun)(struct Animal *a_This);

typedef struct _Animal_Vtable{
   Walk_Fun Walk;
   Dtor_Fun Dtor;
}Animal_Vtable;

typedef struct _Animal{
   Animal_Vtable vtable;
  
   char *Name;
}Animal;

typedef struct _Dog{
   Animal_Vtable vtable;
  
   char *Name; // mirror member variables for easy access
   char *Type;
}Dog;

void Animal_Walk(Animal *a_This){
   printf("Animal (%s) walking\n", a_This->Name);
}

struct Animal* Animal_Dtor(struct Animal *a_This){
   printf("animal::dtor\n");
   return a_This;
}

Animal *Animal_Alloc(){
   return (Animal*)malloc(sizeof(Animal));
}

Animal *Animal_New(Animal *a_Animal){
   a_Animal->vtable.Walk = Animal_Walk;
   a_Animal->vtable.Dtor = Animal_Dtor;
   a_Animal->Name = "Anonymous";
   return a_Animal;
}

void Animal_Free(Animal *a_This){
   a_This->vtable.Dtor(a_This);
  
   free(a_This);
}

void Dog_Walk(Dog *a_This){
   printf("Dog walking %s (%s)\n", a_This->Type, a_This->Name);
}

Dog* Dog_Dtor(Dog *a_This){
   // explicit call to parent destructor
   Animal_Dtor((Animal*)a_This);
  
   printf("dog::dtor\n");
  
   return a_This;
}

Dog *Dog_Alloc(){
   return (Dog*)malloc(sizeof(Dog));
}

Dog *Dog_New(Dog *a_Dog){
   // explict call to parent constructor
   Animal_New((Animal*)a_Dog);
  
   a_Dog->Type = "Dog type";
   a_Dog->vtable.Walk = (Walk_Fun) Dog_Walk;
   a_Dog->vtable.Dtor = (Dtor_Fun) Dog_Dtor;
  
   return a_Dog;
}


int main (int argc, const char * argv[]) {
   /*

[C++] Poker with OOP

2010-07-26T23:34:00.000-07:00

Introduction
I found a OOP question from CSND.
That is how to design a OO with Poker.

Source Code

#include <iostream>
#include <vector>
using namespace std;

enum Suit
{
    Spade = 0,
    Heart,
    Diamond,
    Club
};

class Poker
{
private:
    Suit m_suit;
    int m_number;
public:
    Poker(Suit suit,int number)
    {
        m_suit = suit;
        m_number = number;
    }

    string GetSuit()
    {
        string suit = "Spade";
        if(m_suit == Heart)
            suit = "Heart";
        if(m_suit == Diamond)
            suit = "Diamond";
        if(m_suit == Club)
            suit = "Club";
        return suit;
    }
   
    friend ostream& operator <<(ostream& os, Poker* pk)
    {
        string suit = pk->GetSuit();
        os << "[" << suit.c_str() << ":" << pk->m_number << "]";
        return os;
    }
};

class Cards
{
private:
    vector<Poker*> m_cards;
public:
    Cards()
    {
        for(int i = 0 ; i < 52 ; i++)
        {
            m_cards.push_back(new Poker((Suit)(i / 13), (i % 13)+1));
        }
    }
    void Output()
    {
        vector<Poker*>::iterator iter = m_cards.begin();
        for(; iter != m_cards.end() ; iter++)
        {
            cout<<(Poker*)(*iter)<<endl;
        }
    }
};

int _tmain(int argc, _TCHAR* argv[])
{
    Cards *cards  = new Cards();
    cards->Output();
    int a = 0;
    a = cin.get();
    return 0;
}
