修改webview圖片適配的代碼，是使用js去修改圖片適配屏幕寬度：
// 網絡請求加載的數據,進行字典轉模型 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"--->就是設置圖片的寬度的 * 100%代表正好為屏幕的寬度 */ NSString *htmlString = [NSString stringWithFormat:@"<html> \n" "<head> \n" "<style type=\"text/css\"> \n" "body {font-size:15px;}\n" "</style> \n" "</head> \n" "<body>" "<script type='text/javascript'>" "window.onload = function(){\n" "var $img = document.getElementsByTagName('img');\n" "for(var p in $img){\n" " $img[p].style.width = '100%%';\n" "$img[p].style.height ='auto'\n" "}\n" "}" "</script>%@" "</body>" "</html>",model.details]; // webView直接加載HTMLString [self.webView loadHTMLString:htmlString baseURL:nil];
