1. JailBreak your IPhone/ITouch
It's up to you.It's none of my business.
haha! but be careful,god bless you!
some tips:
- backup all your data
- make sure you know all the pre-requirements
some links & keywords:
Spirit is better.
2. Install JVM in cydia
start cydia
in java section
install all the packages in java section
if you are in China,you may encountered so-called GFW...
you can use a proxy or download and install the deb packages manually
install openssh,this is a must
so you can ssh to your iphone and transfer files
this is optional
3. Set up your development enviroment
first,download the binary here
it contains two jars: iswing.jar and emulator.jar
add them in the classpath,it is so simple.
4. Code
sample desktop hello world program:
------------------
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class HelloWorldApp extends JFrame implements ActionListener {
private JLabel label;
public HelloWorldApp() {
this.setLayout(null);
JButton button=new JButton("Click Me");
label=new JLabel();
this.add(button);
this.add(label);
button.addActionListener(this);
button.setBounds(110,100,100,40);
label.setBounds(50,200,220,50);
label.setBackground(Color.PINK);
label.setHorizontalAlignment(SwingConstants.CENTER);
}
public void actionPerformed(ActionEvent e) {
label.setText("Hello World!");
}
public static void main(String[] args) throws Exception {
HelloWorldApp frame=new HelloWorldApp();
frame.setBounds(100,100,320,480);
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
frame.setVisible(true);
}
}
------------------
it's a simple desktop swing program,and runs like
we change it slightly,like this:
------------------
import javax.iswing.JButton;
import javax.iswing.JFrame;
import javax.iswing.JLabel;
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class HelloWorldApp extends JFrame implements ActionListener {
private JLabel label;
public HelloWorldApp() {
this.setLayout(null);
this.setBackground(Color.WHITE);
JButton button=new JButton("Click Me");
label=new JLabel();
this.add(button);
this.add(label);
button.addActionListener(this);
button.setBounds(110,100,100,40);
label.setBounds(50,200,220,50);
label.setBackground(Color.PINK);
label.setHorizontalAlignment(SwingConstants.CENTER);
}
public void actionPerformed(ActionEvent e) {
label.setText("Hello World!");
}
public static void main(String[] args) throws Exception {
HelloWorldApp frame=new HelloWorldApp();
//frame.setBounds(100,100,320,460);
//frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
frame.setVisible(true);
}
}
------------------
5. Run/Test in the emulator
then it can runs in the emulator
the command line looks like:
java com.saurik.uicaboodle.Main SwingDelegate HelloWorldApp
the programs runs like
6. Package for deployment
launch the iSwing package tool
fill in all infos
add the content(files and folders)
the D:\temp\Hello\bin is my compile output path
then package
7. Deploy and test in real IPhone
remember your ip
sftp to it
upload your files(using sftp client,here winscp)
at the first time,you also upload and install iSwing-xx.deb
ssh to your iphone
here using putty
install iSwing-xx.deb if you has not installed
install the deb package
restart springboard
here using sbsettings
you can also restart your iphone
you will see the app icon
run it
8. Modify and Upgrade
update our program
------------------
import javax.iswing.*;
import javax.iswing.JButton;
import javax.iswing.JCheckBox;
import javax.iswing.JFrame;
import javax.iswing.JLabel;
import javax.iswing.JProgressBar;
import javax.iswing.JSlider;
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class HelloWorldApp extends JFrame implements ActionListener,ReadyListener {
private JLabel label;
public HelloWorldApp() {
this.setLayout(null);
this.setBackground(Color.WHITE);
JButton button=new JButton("Click Me");
label=new JLabel();
this.add(button);
this.add(label);
button.addActionListener(this);
button.setBounds(110,5,100,40);
label.setBounds(50,50,220,50);
label.setBackground(Color.PINK);
label.setHorizontalAlignment(SwingConstants.CENTER);
JDatePicker picker=new JDatePicker();
picker.setBounds(0,105,320,220);
this.add(picker);
JSlider slider=new JSlider();
this.add(slider);
slider.setBackground(Color.WHITE);
slider.setBounds(5,330,310,30);
JProgressBar progress=new JProgressBar(0,100);
this.add(progress);
progress.setBounds(5,365,310,15);
progress.setValue(50);
ActivityIndicator indicator=new ActivityIndicator();
this.add(indicator);
indicator.setBounds(1,1,45,45);
indicator.addReadyListener(this);
JCheckBox check=new JCheckBox();
this.add(check);
check.setBounds(220,5,90,30);
Browser browser=new Browser();
this.add(browser);
browser.setBounds(5,385,310,300);
browser.addReadyListener(this);
}
public void onReady(ReadyEvent e) {
Object source = e.getSource();
if(source instanceof Browser) {
((Browser)source).loadUrl("http://www.google.cn/");
} else if(source instanceof ActivityIndicator) {
((ActivityIndicator)source).startAnimating();
}
}
public void actionPerformed(ActionEvent e) {
label.setText("Hello World!");
}
public static void main(String[] args) throws Exception {
HelloWorldApp frame=new HelloWorldApp();
frame.setVisible(true);
}
}
------------------
test in the emulator
there is a browser control below
we need not pack the program again,
we just upload the classes to the phone directly.
the remote path is /Applications/HelloWorldApp.app/
run it
it is easy to start,isn't it?
any questions,please post in the forum,i'll look through the posts frequently.
:)
