iPad编程教学(2):使用浏览器组件访问web内容

在Xcode中新建一个View-Based应用程序，名叫UsingViews2；
在Interface Builder中放置一个Web view；
UsingViews2ViewController.h的代码如下：

// // UsingViews2ViewController.h // UsingViews2 // // Created by Jiangxd on 10-9-29. // Copyright __MyCompanyName__ 2010. All rights reserved. // #import <UIKit/UIKit.h> @interface UsingViews2ViewController : UIViewController { IBOutlet UIWebView *webView; } @property(nonatomic,retain) UIWebView *webView; @end

在Interface Builder中，将webView outlet和Web view组件连接起来；

UsingViews2ViewController.m代码的内容时：

// // UsingViews2ViewController.m // UsingViews2 // // Created by Jiangxd on 10-9-29. // Copyright __MyCompanyName__ 2010. All rights reserved. // #import "UsingViews2ViewController.h" @implementation UsingViews2ViewController @synthesize webView; /* // 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 { NSURL *url=[NSURL URLWithString:@"http://www.nod6.net"]; NSURLRequest *req=[NSURLRequest requestWithURL:url]; [webView loadRequest:req]; [super viewDidLoad]; } // Override to allow orientations other than the default portrait orientation. - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } - (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 { [webView release]; [super dealloc]; } @end

按Command＋R，运行结果如下：
