一个简单的iPhone项目及代码

iphone NIB文件  -> android xml布局文件

 

iphone delegate class + controller class -> android Activity

 

main方法 -> android的中AndroidManifest.xml要启动的Activity

 

 

步骤:

1. 使用XCODE创建项目

2. 打开nib文件,将需要的组件拖放至view中

3. 在Controller类中声明组件变量 \ 事件接收方法,注意需要 IBOutlet关键字,

4. 使用InterfaceBuilder链接Controller类中的变量\事件接收方法 至 每个组件上

5. 实现事件接收方法

 

(不用InterfaceBuilder依然可以实现UI界面,使用纯Code编写.)

 

main:

//
//  main.m
//  HelloUser
//
//  Created by sin francis on 10-8-26.

//

#import <UIKit/UIKit.h>

int main(int argc, char *argv[]) {
    
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
    int retVal = UIApplicationMain(argc, argv, nil, nil);
    [pool release];
    return retVal;
}

 

Delegate声明:

 

HelloUserAppDelegate.h

 

//
//  HelloUserAppDelegate.h
//  HelloUser
//
//  Created by sin francis on 10-8-26.
//  Copyright __MyCompanyName__ 2010. All rights reserved.
//

#import <UIKit/UIKit.h>

@class HelloUserViewController;


@interface HelloUserAppDelegate : NSObject <UIApplicationDelegate> {
    UIWindow *window;
    HelloUserViewController *viewController;
	
}

@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet HelloUserViewController *viewController;



@end

 

 

Delegata的实现:

HelloUserAppDelegate.m

//
//  HelloUserAppDelegate.m
//  HelloUser
//
//  Created by sin francis on 10-8-26.
//  Copyright __MyCompanyName__ 2010. All rights reserved.
//

#import "HelloUserAppDelegate.h"
#import "HelloUserViewController.h"
#import "MyNewsViewController.h"

@implementation HelloUserAppDelegate

@synthesize window;
@synthesize viewController;


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
    
    // Override point for customization after app launch    
    [window addSubview:viewController.view];
    [window makeKeyAndVisible];
	
	return YES;
}


- (void)dealloc {
    [viewController release];
    [window release];
    [super dealloc];
}


@end

 

 

Controller的声明:

 

//
//  HelloUserViewController.h
//  HelloUser
//
//  Created by sin francis on 10-8-26.
//  Copyright __MyCompanyName__ 2010. All rights reserved.
//

#import <UIKit/UIKit.h>

@interface HelloUserViewController : UIViewController {

	//链接到HelloUserViewController.xib 界面中的display label组件
	IBOutlet UILabel *displayLable;
		//链接到HelloUserViewController.xib 界面中的name Field组件
	IBOutlet UITextField *nameField;
		//链接到HelloUserViewController.xib 界面中的Button组件
	IBOutlet UIButton *sayButton;
	
	//注意:以上的只是引用,并未真实的链接到组件上去,那么就需要我们使用Interface Builder进行链接
	//1. 使用Interface Builder打开HelloUserViewController.xib,打开HelloUserViewController.xib中View
	//2. 右键单击 或者CTRL+左键单击 "File's Owner",可以在弹出的Outlet一栏中看见  
	//displayLable nameField sayButton三个变量名称
	//3. 分别拖动变量右边的空心圈连接至View界面上的组件即可
	
}
//定义一个按钮事件接收器
//如何链接此接收器到button上呢
//1. 使用Interface Builder打开HelloUserViewController.xib,打开HelloUserViewController.xib中View
//2. 右键单击 或者CTRL+左键单击 "File's Owner",在Received Actions一栏中可以看到sayHello的动作
//3. 拖动sayHello右边的空心圈至View界面上的按钮即可
//4. 实现你的sayHello方法吧
-(IBAction) sayHello : (id) sender;

@end

 

 

Contoller的实现:

 

//
//  HelloUserViewController.m
//  HelloUser
//
//  Created by sin francis on 10-8-26.
//  Copyright __MyCompanyName__ 2010. All rights reserved.
//

#import "HelloUserViewController.h"

@implementation HelloUserViewController



/*
// The designated initializer. Override to perform setup that is required before the view is loaded.
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) {
        // Custom initialization
    }
    return self;
}
*/

/*
// Implement loadView to create a view hierarchy programmatically, without using a nib.
- (void)loadView {
}
*/


/*
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    [super viewDidLoad];
}
*/


/*
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
*/

//sayHello的实现方法
-(void) sayHello:(id)sender{

	NSString *userName = nameField.text;
	NSString *helomessage = [[NSString alloc] initWithFormat:@"Hello,%@",userName];
	displayLable.text=helomessage;
	[helomessage release];
	nameField.text=NULL;
}

- (void)didReceiveMemoryWarning {
	// Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];
	
	// Release any cached data, images, etc that aren't in use.
}

- (void)viewDidUnload {
	// Release any retained subviews of the main view.
	// e.g. self.myOutlet = nil;
}


- (void)dealloc {
    [super dealloc];
}

@end
