UIWebView是一个能够显示网页的IOS视图控件，我们可以用它来访问一个网站。下面是具体的实例：
操作步骤：
1.首先在xib文件中拖放一个UIWebView控件到view中
2.将下载的页面以及页面资源加载到项目中，但必须选择Create folder references for any added folders，然后知道文件在项目中是蓝色显示，而不是黄色显示
3.将webView的Delegate拖到File's Owner，继承UIWebView的Delegate协议，并且实现他的协议
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];
//加载本地资源,html页面
NSString *str = [[NSBundle mainBundle] pathForResource:@"百度图片—全球最大中文图片库" 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];
}
@end
