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.//  Copyright __MyCompanyName__ 2010. All rights reserved.//#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
