UIWebView是一個能夠顯示網頁的IOS檢視控制元件，我們可以用它來訪問一個網站。下面是具體的例項：

操作步驟：

1.首先在xib檔案中拖放一個UIWebView控制元件到view中

2.將下載的頁面以及頁面資源載入到專案中，但必須選擇Create folder references for any added folders，然後知道檔案在專案中是藍色顯示，而不是黃色顯示

3.將webView的Delegate拖到File's Owner，繼承UIWebView的Delegate協議，並且實現他的協議

ViewController.h:

#import <UIKit/UIKit.h>

@interface DXWViewController : UIViewController<UIWebViewDelegate>
@property (retain, nonatomic) IBOutlet UIWebView *webview;
@property(nonatomic,retain) UIAlertView *alert;
@end
 

ViewController.m:

#import "DXWViewController.h"

@interface DXWViewController ()

@end

@implementation DXWViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
	NSURL *url = [NSURL URLWithString:@"http://www.baidu.com"];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    //[self.webview loadRequest:request];
    
    //載入本地資源,html頁面
    NSString *str = [[NSBundle mainBundle] pathForResource:@"百度圖片—全球最大中文圖片庫" ofType:@"html"];
    
    str = [NSString stringWithContentsOfFile:str encoding:NSUTF8StringEncoding error:nil];
    NSLog(@"%@",str);
    [self.webview loadHTMLString:str baseURL:[[NSBundle mainBundle] bundleURL]];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (void)dealloc {
    [_webview release];
    [_alert release];
    [super dealloc];
}

-(void)webViewDidFinishLoad:(UIWebView *)webView
{
    [self.alert dismissWithClickedButtonIndex:0 animated:YES];
}

-(void)webViewDidStartLoad:(UIWebView *)webView
{
    self.alert = [[UIAlertView alloc] initWithTitle:@"Loading..." message:nil delegate:nil cancelButtonTitle:nil otherButtonTitles:nil];
    [self.alert show];
    
    UIActivityIndicatorView *aiv = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
    aiv.center = CGPointMake(self.alert.bounds.size.width/2, self.alert.bounds.size.height/2);
    [aiv startAnimating];
    [self.alert addSubview:aiv];
}
