在Ubuntu上iPhone开发教程-1

想开发iPhone应用，没有Mac Book也没有Mac Mini，怎么办？

想尝试在Linux上开发iPhone吗，那就请接着往下看。

 

 

 

1.  前提条件：

在Ubuntu上编译好toolchain，参见我前面的文章。

因为不能跑模拟器，需要一部iPhone手机来测试程序，iPhone3或iPhone4都可以

（目前支持到iPhone 3.1SDK，程序可以在iPhone4上运行）

 

2.  从UIApplication派生你的应用程序类：

 

头文件MyScylla.h

 

#import <CoreFoundation/CoreFoundation.h> #import <UIKit/UIKit.h> @class MyMainView; @interface MyScylla : UIApplication { UIWindow *window; MyMainView *mainView; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet MyMainView *mainView; - (void)applicationDidFinishLaunching:(UIApplication *)application; - (void)dealloc; - (void) redirectConsoleLogToDocumentFolder; @end

 

m文件MyScylla.m

#import <Foundation/Foundation.h> #import <UIKit/UIKit.h> #import <UIKit/UIAlert.h> #import "MyMainView.h" #import "MyScylla.h" int main(int argc, char* argv[]) { NSAutoreleasePool *autoreleasePool = [ [ NSAutoreleasePool alloc ] init ]; int returnCode = UIApplicationMain(argc, argv, @"MyScylla", @"MyScylla"); [ autoreleasePool release ]; return returnCode; } @implementation MyScylla @synthesize window; @synthesize mainView; - (void)applicationDidFinishLaunching:(UIApplication *)application { NSLog(@"applicationDidFinishLaunching"); [self redirectConsoleLogToDocumentFolder]; // 可以用bounds方法会得到整个屏幕区域,包括状态栏 CGRect screenBounds = [ [ UIScreen mainScreen ] bounds ]; // 然后用initWithFrame创建UIWindow对象 window = [ [ UIWindow alloc ] initWithFrame: screenBounds ]; // 用applicationFrame方法返回可显示区域,不包括状态栏 CGRect rect = [ [ UIScreen mainScreen ] applicationFrame ]; rect.origin.x = rect.origin.y = 0.0f; mainView = [[MyMainView alloc]init]; [window addSubview: mainView]; [window makeKeyAndVisible]; } - (void)dealloc { [window release]; [mainView release]; [super dealloc]; } - (void) redirectConsoleLogToDocumentFolder { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *logPath = [documentsDirectory stringByAppendingPathComponent:@"myscylla_log.txt"]; freopen([logPath cStringUsingEncoding:NSASCIIStringEncoding],"a+",stderr); } @end

 

 

3. 定义自己的ViewController

 

CustomViewController.h

#import <UIKit/UIKit.h> @class MyMainView; @interface CustomViewController: UIViewController { UITextView *textView; MyMainView *mainView; } - (void)viewDidLoad; - (void)dealloc; @end

 

CustomViewController.m

 

#import <UIKit/UIKit.h> #import "MyMainView.h" #import "CustomViewController.h" @implementation CustomViewController - (void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor = [UIColor blueColor]; CGRect rect = [ [ UIScreen mainScreen ] applicationFrame ]; mainView = [ [ MyMainView alloc ] initWithFrame: rect ]; [self.view addSubview: mainView]; } - (void)dealloc { [super dealloc ]; } @end

 

4.  定义View

 

MyMainView.h

 

#import <UIKit/UIKit.h> #import <UIKit/UINavigationBar.h> @interface MyMainView : UIView { UINavigationBar *navBar; UINavigationItem *navItem; BOOL isMuted; UITextView *textView; UIButton *button; int count; } @property (nonatomic, retain) IBOutlet UINavigationBar *navBar; @property (nonatomic, retain) IBOutlet UINavigationItem *navItem; @property (nonatomic, retain) IBOutlet UITextView *textView; @property (nonatomic, retain) IBOutlet UIButton *button; -(IBAction) clickButton: (id) sender; - (void)AlertWindow:(NSString *)transValue; - (id)initWithFrame:(CGRect)rect; - (void)dealloc; - (UINavigationBar *)createNavBar: (CGRect) rect; - (void)setNavBar; - (void)clickButton:(id)inSender; - (void)clickButton:(id)inSender forEvent:(UIEvent *)event; //- (void)navigationBar: (UINavigationBar *)navbar buttonClicked:(int) button; @end

 

MyMainView.m

#import <UIKit/UIKit.h>
#import <UIKit/UIAlert.h>

#import "MyMainView.h"

@implementation MyMainView

@synthesize navBar;
@synthesize navItem;
@synthesize textView;
@synthesize button;

- (id)initWithFrame:(CGRect)rect {
    self = [ super initWithFrame: rect ];
      if (self != nil) {
        NSLog(@"start initWithFrame");
       
        isMuted = NO;
        count = 0;
        //navBar = [ self createNavBar: rect];
        //[ self setNavBar ];
        //[ self addSubView: [navBar view] ];
        //NSLog(@"after add navBar");
       
        CGRect rectText = CGRectMake(100,100,300,100);
        textView = [ [ UITextView alloc] initWithFrame: rectText ];
        //[ textView setTextSize: 12 ];
        [ textView setText: @"Hello, world!" ];
        [ self addSubview: textView ];

        button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
        CGRect rect = CGRectMake(120,400,100,50);
        //[sendButton setFrame:rect];
        //sendButton = [ [ UIButton alloc] initWithFrame: rect];
        button.frame = rect;
        [button setTitle:@"Test" forState:UIControlStateNormal];
        [button addTarget:self action:@selector(clickButton:)
        forControlEvents:UIControlEventTouchUpInside];
        //[button addTarget:self action:@selector(clickButton:forEvent:)
        //forControlEvents:UIControlEventTouchUpInside];

        [self addSubview:button];

              
    }
    NSLog(@"end initWithFrame in MyMainView");
    return self;
}

-(void)AlertWindow:(NSString *)transValue{

    UIAlertView *alertView= [[UIAlertView alloc] initWithTitle:transValue message:transValue delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alertView show];
    [alertView release];
}

- (UINavigationBar *)createNavBar: (CGRect) rect {
    NSLog(@"start createNavBar");
    UINavigationBar *newNav = [ [ UINavigationBar alloc]
        initWithFrame: CGRectMake(0.0f, 0.0f, 320.0f, 48.0f)
    ];

    [ newNav setDelegate: self ];
   
    // add our title
    navItem = [ [UINavigationItem alloc] initWithTitle: @"My Navigation" ];
    [ newNav pushNavigationItem: navItem];
    [ navItem setTitle: @"Another Example" ];

    NSLog(@"end createNavBar");
    return newNav;
}
- (void)setNavBar {

    if(isMuted == YES) {
        [ navItem setTitle: @"Spouse (Muted)"];
        [ navBar showLeftButton:nil withStyle: 0 rightButton:@"Mute" withStyle: 1];
    } else {
        [ navItem setTitle: @"Spouse"];
        [ navBar showLeftButton:nil withStyle: 0 rightButton:@"Mute" withStyle: 0];
    }
    NSLog(@"end setNavBar");
}


-(IBAction) clickButton :(id)inSender {
    count++;
    NSLog(@"clickButton");

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Action invoked!" message:@"Button clicked!"
        delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alert show];
    [alert release];
}

-(IBAction) clickButton:(id)inSender forEvent:(UIEvent *)event {
    NSLog(@"clickButton forEvent");
    count++;
    [inSender setTitle:[NSString stringWithFormat:@"count:%d", count]
        forState:UIControlStateNormal];
}


/*
- (void)navigationBar: (UINavigationBar *)navbar buttonClicked:(int) button {
    switch(button) {
    case 1: // left
        [ self AlertWindow: @"Left Button"];
        break;
    case 0: // right
        [ self AlertWindow: @"Right Button"];
        break;
    }
}
*/

- (void)dealloc {
    [textView release];
    [navBar release];
    [navItem release];
    [super dealloc ];
}
@end

5.  Makefile

6. 编译

 

ldid.sh:

export CODESIGN_ALLOCATE=/home/jack/iPhone/toolchain/toolchain/pre/bin/arm-apple-darwin9-codesign_allocate
ldid -S MyScylla
