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http://www.linuxidc.com/Linux/2010-04/25542.htm。
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;
