uiwebview 屏幕自适应 -- 根据 内容适应或者 webview适应

#import <UIKit/UIKit.h> @interface ViewController : UIViewController<UIWebViewDelegate,UISearchBarDelegate>{    UIWebView *webView;    UISearchBar *searchBar;} @end -(void)loadView{                [super loadView];        CGRect bounds = [[UIScreenmainScreen] applicationFrame];        //UISearchBar        searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0, 0.0, bounds.size.width, 48.0)];       searchBar.delegate = self;        searchBar.placeholder = @"Google";   //提示字符    [self.view addSubview:searchBar];        webView = [[UIWebViewalloc] initWithFrame:CGRectMake(0, 48, 320, 432 )];    [webView setScalesPageToFit:YES];                    //自动缩放页面以适应屏幕    [self.view addSubview:webView];                     //连接到一个现有的窗口上    } -(void)searchBarSearchButtonClicked:(UISearchBar *)activeSearchBar{    NSString *query = [searchBar.text stringByReplacingOccurrencesOfString:@" "withString:@"+"];//将“ ”空格替换成“+”    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://www.google.com/search?q=%@",query]];    NSURLRequest *request = [NSURLRequest requestWithURL:url];    [webView loadRequest:request];//链接网络地址}

 //2.用webview显示内容,高度自适应

//webview显示简介内容    UIWebView * webviewinfomationDetails = [[UIWebView alloc] initWithFrame:GRAPH_SIZE_INTRODUCETEXT];    webviewinfomationDetails.backgroundColor = [UIColor clearColor];    [webviewinfomationDetails loadHTMLString:remark baseURL:nil];    [webviewinfomationDetails setUserInteractionEnabled:NO];    [(UIScrollView *)[[webviewinfomationDetails subviews] objectAtIndex:0] setBounces:NO];      [webviewinfomationDetails setScalesPageToFit:NO];     //yes:根据webview自适应,NO:根据内容自适应[webviewinfomationDetails setDelegate:self];    [myScrollView addSubview:webviewinfomationDetails];    [webviewinfomationDetails release];//另一种显示方式//定义WebView显示内容    webviewinfomationDetails = [[UIWebView alloc] initWithFrame:GRAPH_SIZE_WEBVIEW];    [webviewinfomationDetails setScalesPageToFit:NO];  //大小自适应    NSString *path = [[NSBundle mainBundle] bundlePath];    NSURL *base = [NSURL fileURLWithPath:path];    [webviewinfomationDetails loadHTMLString:remark baseURL:base];//链接url    [webviewinfomationDetails setUserInteractionEnabled:NO];//设置用户不可修改    [informationDetailsScroll addSubview:webviewinfomationDetails];    webviewinfomationDetails.delegate=self;    [webviewinfomationDetails release];//webview委托   高度自适应-(void)webViewDidFinishLoad:(UIWebView *)webView{    CGSize actualSize = [webView sizeThatFits:CGSizeZero];    CGRect newFrame = webView.frame;    newFrame.size.height = actualSize.height;    webView.frame = newFrame;        CGSize newsize=CGSizeMake(320, 356+webView.frame.size.height);    myScrollView.contentSize=newsize;}
