  • 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

        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: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

    复制代码
    //webview显示简介内容
        UIWebView * webviewinfomationDetails = [[UIWebView alloc] initWithFrame:GRAPH_SIZE_INTRODUCETEXT];
        webviewinfomationDetails.backgroundColor = [UIColor clearColor];
        [webviewinfomationDetails loadHTMLString:remark baseURL:nil];

        [(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;
    }
