webView

• webView--图片自适应屏幕

1. HTML修改
2. 代码修改

-(void)viewDidLoad {
    [super viewDidLoad];
//  设置webView
    UIWebView *webView=[[UIWebView alloc]initWithFrame:self.view.bounds];
//  1、本地html资源测试
//  NSString *path=[[NSBundle mainBundle]pathForResource:@"test" ofType:@"html"];
//  [webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:path]]];

//  2、URL网址资源测试
    [webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://gb.wallpapersking.com/top/class108/15041/14eec4d8b4bf1fe0.htm"]]];

    [self.view addSubview:webView];
    webView.delegate=self;
}

-(void)webViewDidFinishLoad:(UIWebView *)webView {
    NSString *js=@"var script = document.createElement('script');"
    "script.type = 'text/javascript';"
    "script.text = \"function ResizeImages() { "
    "var myimg,oldwidth;"
    "var maxwidth = %f;"
    "for(i=0;i  maxwidth){"
    "oldwidth = myimg.width;"
    "myimg.width = %f;"
    "}"
    "}"
    "}\";"
    "document.getElementsByTagName('head')[0].appendChild(script);";
    js=[NSString stringWithFormat:js,[UIScreen mainScreen].bounds.size.width,[UIScreen mainScreen].bounds.size.width-15];
    [webView stringByEvaluatingJavaScriptFromString:js];
    [webView stringByEvaluatingJavaScriptFromString:@"ResizeImages();"];
}

在请求内部设置

// 网络请求加载的数据,进行字典转模型
NSDictionary *dict = [result objectForKey:@"data"];
HQNewsDetailModel *model = [HQNewsDetailModel mj_objectWithKeyValues:dict];

/**
 * model.details就是后台返回的HTMLString
 * " $img[p].style.width = '100%%';\n"--->就是设置图片的宽度的
 * 100%代表正好为屏幕的宽度
 */
NSString *htmlString = [NSString stringWithFormat:@" \n"
                   " \n"
                   " \n"
                   " \n"
                   ""
                   "%@"
                   ""
                   "",model.details];

// webView直接加载HTMLString
[self.webView loadHTMLString:htmlString baseURL:nil];
